Fix: ctf: notif-iter: do not call request_medium_bytes() when not needed
Do not systematically call request_medium_bytes(), that is, at the
beginning of read_dscope_begin_state(), because the scope field which is
about to be decoded might be empty, an already aligned structure
field or the equivalent (through a variant field for example, of which
the tag is outside this scope).
To do this we also need to make bt_btr_start() accept a size of 0. In
this case, if the field to decode is an empty structure which is already
aligned, then bt_btr_start() does not need to consume any bit and
returns BT_BTR_STATUS_OK with 0 consumed bits. In this case, the next
notif-iter state is not a continuing state, thus request_medium_bytes()
is not called yet.
Checking for a bad state when request_medium_bytes() receives
BT_NOTIF_ITER_MEDIUM_STATUS_EOF from the medium is easier. Good states
are:
* If the current packet size is set:
** Current packet offset is current packet size.
* Otherwise:
** Current packet offset is 0.
** Last event header offset is set and current offset is equal to it.
All other states are invalid.

ctf, ir: escape and unescape enumeration FT labels starting with `_`
This is a solution to work with TSDL 1.8 which asks identifiers starting
with `_` to be named without the `_` for viewing and analysis purposes.
Since a variant FT can refer to an enumeration FT tag which also has its
labels starting with `_`, we systematically remove leading `_` in
enumeration FT labels too.

enum {

__zoom,

variant <tag> {
A _salut;
B hello;

hello,
_zoom,

} tag;
variant <tag> {
A salut;
B hello;
C _zoom;
D integer;
} var;
Once back to TSDL (through CTF writer), it is:

Rename bt_ctf_X -> bt_X, maintain backward compat. for pre-2.0 CTF writer
This patch replaces the `bt_ctf_` prefix with `bt_` for all the
functions, types, and enumerations. It also replaces the `BT_CTF_`
prefix with `BT_` for all the preprocessor definitions and enumerators.
Since there is only one IR as of Babeltrace 2, there is no need for this
superfluous prefix: there's no confusion without it, and it might even
be more straightforward for the newcomer to see `bt_trace` instead of
`bt_ctf_trace`, for example.
Backward compatibility is maintained with the help of specific
preprocessor definitions placed in each relevant public header file to
create aliases for legacy function names, type names, enumerator names,
and preprocessor definition names. Because Babeltrace 2 asks current
applications to be rebuilt anyway (soname is bumped), it is okay to lose
some symbol names as long as the API is equivalent.
The only possible issue that I can see is if an application uses a new
API name as a variable name, for example:
struct bt_ctf_trace bt_ctf_trace;
struct something_else bt_trace;
This is an error after this patch is applied because, after the
preprocessor pass, it is the equivalent of:
struct bt_trace bt_trace;
struct something_else bt_trace;
because of (include/babeltrace/ctf-ir/trace.h):
#define bt_ctf_trace bt_trace
which affects both the type name and the variable name. This should not
be a problem in most cases, and it is easy to fix otherwise.

This reference cycle can make some tests fail because, with the

count must be "stable" and as deterministic as possible so as to avoid

Fix: remove underscores from CTF IR field names at the source
The CTF spec. states that if a structure field type's field name or a
variant field type's choice name starts with `_` in the TSDL metadata
stream, then this underscore should be removed from the effective
field/choice name.
This patch applies this at the source (src.ctf plugin), in the TSDL
metadata text to CTF IR objects visitor. To do so it must also remove
such underscore characters from the components of field references (tag
and length names).
The behaviour is removed from plugins/text/pretty/print.c which did it
at the output level.
A potential issue is that a variant field type can have its enumeration
tag field type contain mappings which still have the underscore
prefixes. To circumvent this, we add the field names and the field names
with underscores to the field types's hash tables of field names to
field indexes, so that `field_name` and `_field_name` refer to the same
index within the structure/variant field type, for example.
When serializing the structure/variant field types to TSDL (for the CTF
writer API), we prefix each field with `_` if it's a CTF identifier so
as to avoid conflicts. We also remove the check that structure/variant
field type field names must not be CTF identifiers since it is safe to
serialize them now.

* The `timestamp_begin()`, `timestamp_end()`, and `_has_intersection()`
methods of `babeltrace.TraceHandle` perform the `trace-info` query
with their path to retrieve the information.
* The `babeltrace.TraceHandle.events` property creates a `bt2` trace
collection notification iterator, gets the first notification of the
trace (which is expected to be a stream beginning notification), and
finds the CTF IR trace object to generate all the event declarations
from event classes using
`babeltrace.reader_event_declaration._create_event_declaration()`.
* The `babeltrace.TraceCollection.events` property creates a `bt2` trace
collection notification iterator, in stream intersection mode if
needed, and with a beginning and end time if needed, and generates
event objects using `babeltrace.reader_event._create_event()`.

bt2: values: remove public `value` getter
The public `value` getter (e.g., `my_int_value.value`) is redundant here
since the `bt2.values` object already act like their Python equivalent.
If you need an `int` value out of a `bt2.IntegerValue` object, for
example, you can just use `int(bt_value)` instead of `bt_value.value`.
We keep the `value` setter because this is used to set the underlying
raw value.
Internally, we keep the private `_value` getter to access the object's
raw value.
In the tests, we copy the value to modify instead of using the `value`
property with this pattern:
orig_value = copy.copy(value)
# modify value
self.assertEqual(value, orig_value)

Avoid unnecessary inclusions in public headers
Featured in this patch:
* In public headers, only include what is really needed by the
declarations of the header itself. Copy forward declarations when
possible instead of including just for the included file's forward
declaration. Also indicate above each included header why it is
included to justify it.
This should prevent future bugs where we could, for example, remove an
included header to replace it by a forward declaration, breaking some
builds which relied on indirect inclusion (e.g. my project does not
need to include <babeltrace/values.h> because it includes
<babeltrace/ctf-ir/event-class.h>).
* Make all the plugin C source/header files include
<babeltrace/babeltrace.h> instead of a bunch of public headers. This
does not significantly increase the build time while making the source
file much cleaner.

lib: add output port notification iterator
As of this patch, you can create an output port notification iterator
with a component's output port with
bt_output_port_notification_iterator_create(). This function, on
success:
1. Creates a notification iterator object, which contains a
notification pointer.
2. Adds (creates) a colander sink component, passing this notification
pointer's address to its initialization method data, along with
a list of notification types to subscribe to received as a
parameter.
3. Connects the passed output port to the colander component's input
port.
4. Makes the targeted graph nonconsumable. This means, at this point,
only bt_notification_iterator_next() can consume the graph, not the
user.
5. Returns the created notification iterator.
When you call bt_notification_iterator_next() with this new notification
iterator, it puts its current notification and consumes its specific
colander sink within the graph to make it store the next notification,
forwarding any exceptional graph status as a notification iterator
status.
More than one output port notification iterators on a single graph are
supported: multiple colander sinks are added to the graph and each one
makes its own colander sink consume.
To avoid immediate or eventual component name clashes,
bt_output_port_notification_iterator_create() accepts an optional
colander name parameter. If you use NULL, then `colander` is used.

Split notification iterator API into base and specialized functions
This patch splits the notification iterator API into base functions
(<babeltrace/graph/notification-iterator.h>) shared by all notification
iterators:
* bt_notification_iterator_next()
* bt_notification_iterator_get_notification()
and specialized functions
(<babeltrace/graph/private-connection-notification-iterator.h>):
* bt_private_connection_notification_iterator_get_component()
This allows the future creation of specialized notification iterators
which can use the common API for basic operations. A "private connection
notification iterator", the only type of notification iterator as of
this patch, is a notification iterator created from a private connection
with bt_private_connection_create_notification_iterator().
The bt2 Python package is updated accordingly.
_GenericNotificationIterator has only the __next__() method, while
_PrivateConnectionNotificationIterator extends
_GenericNotificationIterator with the `component` property.
The name "private connection" is excluded from component class type
definitions and functions, and also from plugin development macros,
because this is the only type of notification iterator which a user can
provide anyway, for example:
* bt_component_class_notification_iterator_init_method
* bt_component_class_source_set_notification_iterator_init_method()
`bt_notification_iterator_next_return` is renamed to
`bt_notification_iterator_next_method_return` to indicate that this is
the user notification iterator's "next" method return type.
`bt_component_class_query_return` is renamed to
`bt_component_class_query_method_return` to match this convention.
