1685f38bb2 gsttracer: Add new API to fetch the list of active tracers
This will be useful in the next commit where we add action-signals on
the leaks tracer to get information about leaks and to manipulate
checkpoints as a replacement for the SIGUSR1 and SIGUSR2 signals for
doing the same.

6577f5e91e gsttraceutils: actually disable tracing system hooks if configured
`./configure --disable-gst-tracer-hooks` didn't do anything, hooks were
always enabled regardless of the option. It works correctly in the
Meson build though.

7e5a892f89 tracer: Initialize GstTracer _priv_tracers and quarks unconditionnally
Some people might use tracer hooks even if GST_TRACER_PLUGINS is not
set.

8b88fc487f gst.h: Don't spew warnings if GST_USE_UNSTABLE_API is not defined
Only hide GstTracer and GstTracerRecord API behind GST_USE_UNSTABLE_API,
but don't spew any warnings, otherwise everyone has to define this
to avoid compiler warnings.

This reverts parts of commit 89ee5d948d.

89ee5d948d tracer: add a GFlag for the tracer scope
Port all tracers. Add the GST_USE_UNSTABLE_API flag to the internal CFLAGS so
that we don't have to specify this for gir, docs, mkenum, ...

9d91ad0b85 tracer: Use GST_DISABLE_GST_TRACER_HOOKS instead of GST_DISABLE_GST_DEBUG everywhere
Previously we used the latter one still for the tracer utility code, causing
undefined references in the resulting binary if the debugging system was
disabled but the tracer system not.

5e40639be7 tracer: make gst_tracing_register_hook_id static
We don't need to expose this as public API. Change the only plugin that was
using it.

82c1ec4931 tracer: add element-change-state-pre/post hook
Helps catching when a state change is starting and ending.

It is also possible to track the end of state changes by checking the
async-done or state-change messages.
This is particularly important for elements that do async state changes.

660049bb38 tracing: rename the global api to gst_tracing
This makes it more obvious what is the api for tracer elements and what is api
for the global state.

5e2770566f tracers: eliminate var_args
Register tracer hooks as GCallback. Use macros for hook dispatch and cast the
hook functions back to the appropriate type.

4881d1c16c tracer: use GQuark or strings for the hook id
This way one can define new tracing probes without changing the core. We are
using our own quark table, as 1) we only want to initialize them if we're
tracing, 2) we want to share them with the tracers.

1a3e218b89 tracer: simplify hook api
Instead of a single invoke() function and a 'mask', register to individual
hooks. This avoids one level of indirection and allows us to remove the
hook enums. The message enms are now renamed to hook enums.

7b24d76260 tracer: drop the HookId hid from the invoke method

46ea9729df tracer: split into tracer and tracerutils
Keep tracer base class in tracer and move core support into the utils module.
Add a unstable-api guard to the tracer.h so that external modules would need to
acknowledge the status by setting GST_USE_UNSTABLE_API.
