ctf plugin: add CTF metadata decoder API
The new plugins/ctf/common/metadata/decoder.h header exposes the CTF
metadata decoder API. This is a common API used by both the ctf.fs and
ctf.lttng-live component classes.
Once you create a CTF metadata decoder object with
ctf_metadata_decoder_create(), you can call
ctf_metadata_decoder_decode() as many times as needed to decode chunks
of metadata. Those chunks can be packetized or not, however the
resulting metadata text needs to be "complete", that is, zero or more
top-level TSDL blocks ("declarations"). If ctf_metadata_decoder_decode()
cannot decode because the metadata text is incomplete, the function
returns CTF_METADATA_DECODER_STATUS_INCOMPLETE. It is then the caller's
responsibility to keep the existing metadata and append more metadata
to it and then call ctf_metadata_decoder_decode() again with this,
until the function returns CTF_METADATA_DECODER_STATUS_OK or another
error.
At anytime you can get the CTF metadata decoder's associated CTF IR
trace object with ctf_metadata_decoder_get_trace(). The trace object is
initially empty: as you call ctf_metadata_decoder_decode(), the decoder
makes it grow by adding other CTF IR objects to it: stream classes,
event classes to new or existing stream classes, clock classes, etc.
The public ctf_metadata_decoder_is_packetized() and
ctf_metadata_decoder_packetized_file_stream_to_buf() functions exist
only for the `metadata-info` ctf.fs query for the moment.
Also in this patch:
* The identical btr/print.h and notif-iter/print.h is moved to
metadata/print.h.
* A fix is added to the AST-to-CTF IR visitor to pop the current
declaration scope at the end of visit_event_decl().

converter/babeltrace-log.c still exists, but it's not build as of this
patch because it uses the legacy API. We need to change this to use CTF
writer and add it to the Makefile again.
Some debug info files are gone because they also use the legacy API.
They are updated anyway as part of the upcoming debug info component
class.
The Python bindings are not covered by this patch: a subsequent patch
should fix them at once.
Some tests which used the legacy API are removed.
The legacy include files are removed, except for
include/babeltrace/ctf/event.h which could be included by CTF writer
users. The file simply includes all the CTF writer header files now.
The functions to serialize integer and floating point number fields
are moved to lib/ctf-writer/serialize.c where a light
`struct bt_ctf_stream_pos` exists along with a few helper functions
for this renamed legacy object. The serialization functions use BT 2
objects now so that the dependency on the legacy API can be dropped.
The serialization functions accept a native byte order parameter now.
When a field type has a "native" byte order, the real (passed) native
byte order must be used. This ensures that:
* CTF IR objects do not need to propagate the trace's native byte order
to all the contained field types.
* Two references to the same field type which are part of two different
trace objects can have a native byte order without causing byte order
overwriting bugs.
The CTF IR code is simplified with this change. Also the
bt_ctf_trace_set_byte_order() function refuses the
BT_CTF_BYTE_ORDER_NATIVE byte order.
I also added internal inline functions to quickly access the parent
of some CTF IR object without getting a new reference:
* bt_ctf_event_borrow_event_class()
* bt_ctf_event_class_borrow_stream_class()
* bt_ctf_stream_class_borrow_trace()
Since the CTF parser test in formats/ctf/metadata/ was a legacy tool,
it's removed in this patch. It's not used anymore by test_ctf_writer
(only the converter runs to validate the generated trace).
Leaks are fixed in test_ctf_ir_ref and test_trace_listener.

Visibility: split graph API into public and private interfaces
The goal here is to avoid that a component or a graph user calls methods
that do not logically apply to itself, but should according to the API's
intention. For example, a component should not be able to remove the
ports of another component, and a graph user should not be able to
create a notification iterator directly.
Therefore the existing bt_component, bt_port, bt_connection, and
bt_notification_iterator objects are considered "public": any user can
call their API.
The user-defined methods (callbacks) now accept private versions of
those objects:
* bt_private_component
* bt_private_port
* bt_private_connection
* bt_private_notification_iterator
This ensures that only the user which is called back with those private
objects can call specific, private methods, which start with the
`bt_private_` prefix.
For example, any user can get a sink component's input port by name with
bt_component_sink_get_input_port(). This function accepts a bt_component
object parameter and returns a bt_port object. However, only the called
back user can get its private version of the port with the equivalent
bt_private_component_sink_get_input_private_port(). This function
accepts a bt_private_component object parameter and returns a
bt_private_port object. The private port API has the
bt_private_port_remove_from_component() function: thus only the owner
component of a port can remove it from itself.
Each private API has a bt_OBJ_from_private_OBJ() function which
returns a _new reference_ to the equivalent public object of a private
object to be able to call public functions.
With all this, if a user calls a private function with a public object,
the compiler emits a warning similar to:
warning: assignment from incompatible pointer type
With GCC and Clang, you can make this warning an error with:
-Werror=incompatible-pointer-types

Allow a component to remove a port and any user to disconnect one
This patch allows a component to remove one of its own ports at anytime.
Removing a connected port has the side effect of also disconnecting it.
This patch also allows any user (graph's creator or component, for
example) to disconnect a component's port.
A component can remove one of its port with
bt_port_remove_from_component(). This function only needs the port
object because the removing component is its parent. Note that this
function does not check in any way that the removing component is the
parent of the port to remove from its parent, so any component or even
the graph's user could remove any component's port. This is prohibited
by the API's contract, but it's not enforced. It should be documented
accordingly.
You can disconnect a port with bt_port_disconnect(). When you call this
function, both upstream and downstream ports of the port's current
connection are disconnected, that is, they become available again for
bt_graph_connect().
When a port is disconnected with bt_port_remove_from_component(), the
parent component's of the connection's other port is called back ("port
disconnected" method) to notify it that one of its ports lost a
connection. Then the component is free to keep this port as an available
port, or to remove it too.
When a port is disconnected with bt_port_disconnect(), both
components are called back ("port disconnected method").
The existing iterators on a connection which is dropped (ports are
disconnected) are left as is: they still work.
The "new connection" optional method is renamed to "accept port
connection": this method can return
BT_COMPONENT_STATUS_REFUSE_PORT_CONNECTION to explicitly refuse the
new connection.
With this patch, only one connection per port is allowed. This
simplifies the model. One-to-many connections can be replaced with
a "tee" filter. Thus this patch removes the concept of a maximum number
of connections per port (it's always one).
With this patch, a component can add a new port at anytime, not just
during its initialization.
Also in this patch: the input and output ports are part of the
bt_component object. The public API is not changed. This avoids some
code duplication.

CLI: add `run` command and make `convert` command use it
This patch adds the babeltrace(1) command `run` which is essentially the
same as the current `convert` command without the magic stuff (legacy
options and their interesting constraints), plus this:
* You can set the name of a component by prefixing the --source,
--filter, or --sink option's argument with `NAME:`. You can escape
`.`, `:`, and `\` with `\`. Example:
--source=instance:ctf.fs --sink=my-text:text.text
--filter='my\.name:my\.plugin.my\.comp\.cls'
This is the equivalent of:
--source=ctf.fs --name=instance --sink=text.text --name=my-text
--filter='my\.plugin.my\.comp\.cls' --name my.name
The --name option still exists: it sets the current name of the
current component, so that, with this:
--sink=a:b.c --name=salut --name=bonjour
the effective name of this component is `bonjour`.
* You can use the new --key and --value options to add one string
initialization parameter to the current component. The name of this
parameter is given by the last --key option's argument, and its value
by the --value option's argument. Examples:
--source=ctf.fs --key=path --value ~/lttng-traces/...
--key=path --source=ctf.fs --value ~/lttng-traces/...
This is useful to not care about the specific escaping required by the
--params option format for a string parameter, to use any parameter
name, and to use shell expansion for the value (tilde expansion for
example, as --path is not a `run` command's option).
The `convert` command is now a specialization of the `run` command,
specific to a _conversion graph_ (whereas the terminology for what you
build with the `run` command is a _processing graph_). The conversion
graph that the `convert` command builds always has the following
topology:
sources -> utils.muxer -> [utils.trimmer] -> lttng-utils.debug-info -.
.-------------------------------------------------------------'
'-> [user filters] -> sinks
There's no more --connect option in the `convert` command. When you run
the `convert` command, it prepares the equivalent `run` command
arguments and invokes the latter directly. However if `-o ctf-metadata`
exists, a new "print CTF metadata" command configuration is created, and
if `-o lttng-live` exists with a URL missing a session name, a new
"print LTTng-live sessions" command configuration is created.
New `convert` options are:
--color=(always | auto | never)
Adds the `color` initialization parameter set to the corresponding
value to the implicit text.text sink component.
--no-debug-info
Do not add an implicit lttng-utils.debug-info filter component to
the filter chain. The lttng-utils.debug-info filter always exists
otherwise.
--run-args
Instead of invoking the `run` command, prints to the standard output
the equivalent `run` command arguments, formatted for a shell. This
means you can copy the whole output and use it as is to execute
`babeltrace run` without escaping, so that the two following
commands are equivalent:
babeltrace convert [...]
babeltrace run $(babeltrace convert --run-args [...])
You can also use this trick to augment the conversion graph with the
`run` command, for example:
babeltrace run --base-params common-to-each-convert-comp=23
$(babeltrace convert --run-args /path/to/trace
--source=src:my.source [...])
--reset-base-params
--sink=special-sink:my.sink
--connect=src.some-port:special-sink
--run-args-0
Like --run-args, but does not escape the individual arguments for a
shell, and uses the null character as the argument delimiter. This
is useful to get the list of equivalent raw arguments outside a
shell (in a user program), or to use `xargs -0`.
--url=URL
Set the `url` initialization parameter of the current user component
to URL.
Lost `convert` options are:
* --base-params
* --connect
* --reset-base-params
Note that --clock-force-correlate sets the boolean `force-correlate`
initialization parameter of the implicit utils.muxer filter to true.
The necessary conditions to instantiate implicit components are now:
* Implicit ctf.fs source: any of:
* Leftover argument and no --input-format
* Leftover argument and --input-format=ctf
* Leftover argument and --clock-offset
* Leftover argument and --clock-offset-ns
* Leftover argument and --stream-intersection
* Implicit ctf.lttng-live source: any of:
* Leftover argument and --input-format=lttng-live
* Implicit utils.muxer filter: always exists
* Implicit utils.trimmer filter: any of:
* --begin
* --end
* --timerange
* Implicit lttng-utils.debug-info filter:
* No --no-debug-info
* Implicit utils.dummy sink:
* --output-format=dummy
* Implicit text.text sink: any of:
* No --output-format and no --sink
* --output-format=text
* --clock-cycles
* --clock-date
* --clock-gmt
* --clock-seconds
* --color
* --fields
* --names
* --no-delta
* --output
The default names of the implicit components, given by the `convert`
command, to be used by the `run` command, are:
* Implicit ctf.fs source: `ctf`
* Implicit ctf.lttng-live source: `lttng-live`
* Implicit utils.muxer filter: always exists `mux`
* Implicit utils.trimmer filter: `trim`
* Implicit lttng-utils.debug-info filter: `debug-info`
* Implicit utils.dummy sink: `dummy`
* Implicit text.text sink: `text`
If any name is already taken by an explicit user component (--source,
--filter, and --sink), the rule is to try `NAME-0`, then `NAME-1`, then
`NAME-2`, etc. The same rule applies to unnamed user components.
Implicit components are always automatically named after automatically
naming the unnamed user components.
This patch also adds the following:
* Connection cycle detection in babeltrace-cfg-connect.c.
* bt_common_string_until() which returns a substring from a given point
to one of a set of terminating characters, possibly with escapable
characters.
* bt_common_shell_quote() which quotes a string (if necessary) for a
shell.
* bt_common_string_is_printable() which checks if a string contains
only printable characters, including whitespaces.
* bt_common_parse_lttng_live_url() to parse a LTTng-live URL. This is
needed in both the LTTng-live plugin itself and babeltrace-cfg.c to
know if the command is a `run` command or a "print LTTng-live
sessions" command.
* The --name, --source, --filter, --sink, and --connect arguments are
checked with bt_common_string_is_printable().
