cpp-common/bt2c: add `DataLen` class (general-purpose data length)
This patch adds the `bt2c::DataLen` class so that you can make sure your
function accepts an expected data length instead of specifying that you
need bits or bytes:
Something buildSomething(bt2c::DataLen len, ...)
{
using namespace bt2c::literals::datalen;
if (...) {
len += 16_MiBytes;
} else {
len *= 2;
}
// ...
}
// ...
const auto something = buildSomething(DataLen::fromBytes(sz), ...);
As you can see above, you can use the `bt2c::literals::datalen`
namespace to access handy data length user literals.
The `bt2c::DataLen` constructor is private: you need to use the
bt2c::DataLen::fromBits() and bt2c::DataLen::fromBytes()
static methods to build an instance.
Because a `bt2c::DataLen` instance is just an `unsigned long long`
value in memory, the intention of this API is to copy data length
instances as much as possible. Therefore, I suppose it's cheaper to
accept a `const bt2c::DataLen` parameter than
`const bt2c::DataLen&` which would add an indirection.
The constructor and many methods are `constexpr` to make this useable in
constant context.

- clock offset (seconds)
- clock offset (nanoseconds)
- force origin to be Unix epoch
Gather these three values in a new structure, `ClkClsConfig`, so that
these they can easily be passed around. This replaces the existing
ctf_fs_metadata_config structure, which contained the exact same thing,
but was specific to the fs component class.

src.ctf.fs: remove uneeded check in create_streams_for_trace
At this point, we certainly have a stream class.
The ir_sc field is set in ctf_stream_class_to_ir.
ctf_stream_class_to_ir is called by ctf_trace_class_translate, which is
called by ctf_visitor_generate_ir_visit_node if ctx->trace_class is set.
That trace_class field is set if a self_comp was passed to
ctf_visitor_generate_ir_create, in the decoder_config object. Going up
the stack, we get to ctf_fs_metadata_set_trace_class, called by
ctf_fs_trace_create, called by ctf_fs_component_create_ctf_fs_trace.
create_streams_for_trace is called by ctf_fs_trace_create, which always
passes a self_comp to ctf_fs_component_create_ctf_fs_trace, ensuring we
always end up with a stream class.
ctf_fs_component_create_ctf_fs_trace is also used in the context of
queries, where no self_comp if passed, and therefore no stream class is
created.. But in that context, create_streams_for_trace is not called.

ctf: use `bt2c::Logger` throughout `src.ctf.fs`, `src.ctf.lttng-live`
A lot of functions and structures have parameters or fields of type
`bt_self_component`, `bt_self_component_class` and `bt_logging_level`
for the sole purpose of logging. This becomes quite verbose, especially
when a function can be used in both self component and self component
class context, then it will have both of these parameters.
The `bt2c::Logger` class exists to encapsulate this context in a single
value that can be passed around. Use it as much as practically possible
(as well as the corresponding logging macros) throughout the sources of
the ctf plugin, as well as in the common directory that they depend on.
Update all format strings to use {fmt}'s format string syntax.
Change all "enum to string" functions to be `format_as()` functions
understood by {fmt}. Move these functions near the type they format,
for convenience.
Remove all the macros that appear at the beginning of source files that
influence the logging (such as `BT_COMP_LOG_SELF_COMP` and `BT_LOG_TAG`).
The log tags were previously defined per-source file, whereas they are
now defined per `Logger` object. I tried to re-use the existing log
tags when it made sense, but in some places the log tags are now a bit
more granular.
Remove the `ctf_plugin_metadata_log_level` variable, controlled by the
`BABELTRACE_PLUGIN_CTF_METADATA_LOG_LEVEL` environment variable. This
variable controlled the logging level in the lexer and parser (generated
by flex and bison). It existed because the generated lexer and parser
don't provide an easy way to pass user data around.
Work around this by define the following variable:
thread_local const ctf_scanner *currentCtfScanner;
and making the logging in the lexer and parser code use
`currentCtfScanner->logger`. Set `currentCtfScanner` when entering the
parser in `ctf_scanner_append_ast()` and install an RAII cleanup to
reset it.

Change naming convention for enum class enumerators
Change the naming convention for enum class enumerators to not use
`ALL_CAPS`, as suggested by the C++ Core Guidelines [1]. Instead, use
camel case starting with a capital letter.
Update `CONTRIBUTING.adoc` to reflect this change.
gcc emits warnings like this:
/home/smarchi/src/babeltrace/src/cpp-common/bt2/trace-ir.hpp:880:9: error: declaration of 'bt2::CommonEventClass<LibObjT>::LogLevel::Error' shadows a global declaration [-Werror=shadow]

Whether or not this is a compiler bug is not clear [2], but in our case
we know it's fine. Add and use `BT_DIAG_IGNORE_SHADOW` in some places
to silence these warnings.

For 'in-tree' builds all the paths are relative and thus compatible with
native windows binaries while in an 'out-of-tree' build some of the
paths are absolute and thus incompatible. The MSYS2 shell does a lot of
'magic' conversion [1] on paths passed as arguments and through environment
variables but the heuristics are limited and it doesn't apply when
binaries are called directly without using the shell.
The first issue is the include paths in the CFLAGS and CPPFLAGS
environment variables which don't get converted because they start with
'-I'.
The second issue is that the path to 'logging.c' in the generated
'setup.py is absolute:
sources=["bt2/native_bt.c", "/home/smarchi/src/babeltrace/src/bindings/python/bt2/bt2/logging.c"],
When distutils invokes gcc to compile this file, it spawns it directly,
not through a shell, so no automatic Unix -> Windows path conversion
takes place.
Fix both of those issues by modifying 'setup.py' to detect the MSYS2
environment and convert absolute path to Windows style using the
'cygpath' command.

As of this patch, everything which was part of

be shared with CTF 2 sources eventually and move back to
`src/plugins/ctf/common/src/metadata`.
`print.hpp` isn't needed anymore.

cpp-common/bt2: use universal reference for `Graph::addComponent()` initialization data
I noticed it was not possible to pass data to `Graph::addComponent`
using a temporary object:
graph->addComponent(*srcCompCls, "source-1", TestSourceData {});
My understanding of it is that the compiler does not consider the
overload with the `InitDataT&` parameter for this, because the temporary
object can't bind to the lvalue reference.
Change these methods to take forwarding references instead.

Fix: flt.utils.muxer: reject two different clock classes with unknown origin and no UUID
When getting a message with a clock class whose origin is unknown and
that has no UUID, the expectation of a `flt.utils.muxer` component
should be that all subsequent messages with an associated clock class
will have the exact same clock class instance. Currently, it accepts
any other clock class instance that has an unknown origin and no UUID.
This is a change that is equivalent to what was done in commit
29e191fceb61 ("Fix: lib: strengthen clock expectation check for no Unix
epoch / no UUID case") in the library iterator code.
When first seeing a clock class with unknown origin and no UUID, make
the muxer message iterator save the clock class instance, holding a
strong reference, and ensure that all clock classes seen after are the
same instance.

Add C++ bindings to access the error on the current thread.
- Take the current thread error with takeCurrentThreadError(),
returning a `UniqueConstError`.
- Move the current thread error back with moveErrorToCurrentThread().
- Access the error cause by iterating or subscripting
`UniqueConstError`, which yields objects of type `ConstErrorCause` (a
borrowed object type).
- Access the common error cause information using methods of
`ConstErrorCause`, including the error cause actor type.
- Obtain a more specific error cause object with
`ConstErrorCause::as*()`.

lib/graph/iterator: use clock correlation validator util
Make `graph/iterator.{c,h}` use the clock correlation validator
convenience library.
- Replace the fields of `struct bt_message_iterator` that track the
clock expectation state with a single `struct
bt_clock_correlation_validator` field, only present if babeltrace is
built in dev mode.
- Initialize `bt_message_iterator::correlation_validator` in
create_self_component_input_port_message_iterator. Finalize it in
`bt_message_iterator_destroy`.
- Replace the bulk of
`assert_post_dev_clock_classes_are_compatible_one` with one call to
`bt_clock_correlation_validator_validate_message`. If the latter
returns an error, trigger an assertion failure based on the return
error type and associated information.
The modifications in the Makefiles (adding `dummy.cpp`) are to force
linking with the C++ compiler driver. This is necessary, since the
`libbabeltrace2.so` library now requires some symbols from the C++
standard library (e.g. `libstdc++.so`). The `dummy.cpp` does not
actually need to exist. This trick is described in the automake doc
[1].

Since the lib is written in C and the muxer component in C++, we need
both interfaces. I chose to write the core of the library with a proper
C++ interface (since that's the future!) and make a small C wrapper
around it. If/when we migrate some parts of the lib to C++, we will be
able to drop this C wrapper.
