When allocating a new buffer in the pool, both the do_alloc_buffer() and the
vmethod, alloc_buffer(), receive the parameter GstBufferPoolAcquireParams.
Nonetheless, when default_acquire_buffer() calls the do_alloc_buffer() it does
not pass the received GstBufferPoolAcquireParams, so when the user pass those
parameters they are ignored by alloc_buffer() vmethod.
This one-liner patch pass the received acquire params to do_alloc_buffer().

Fixes a race where an entry is set to BUSY in
gst_system_clock_id_wait_jitter() and is UNSCHEDULED before
gst_system_clock_id_wait_jitter_unlocked() starts processing it. The
wakeup added by gst_system_clock_id_unschedule() must be cleaned up.
Two stress tests are added. One test that triggers the specific issue
described above. The second stresses the code path where a wait is
rescheduled because the poll returned early.
https://bugzilla.gnome.org/show_bug.cgi?id=761586
If the clockentry is too late and is unscheduled before it gets
a change to detect its lateness the wakeup count and the poll are
used but never properly cleaned up. This leaves it in a dirty state
that is going to mess with the next clock entry waiting requests.

Change the gst_tracer_record_new() api to take the parameters the make the
spec structure directly. This allows us to own the top-level structure and
also collect the args so that we can take ownership of the sub-structures.

We're comparing a pointer type with '\0' here, which
probably isn't right, and the loop condition made sure
that classes[0] is != NULL already, so it's pointless.
Was probaby meant to check if the string pointed to is
not empty, so make it do that instead.
When choosing the first entry from the list, gst_system_clock_async_thread
must set the entry state to busy before releasing the clock lock. Otherwise
a new entry could be added to the beginning of the list and
gst_system_clock_async_thread will be unaware and keep waiting on the entry
it has already chosen.
Also improved messages about expected state and bumped them to ERROR level
to detect unexpected state changes.

self->spec is got using g_value_get_boxed(), which is a transfer none function.
So the same should not be freed, which is resulting in wrong behavior.
https://bugzilla.gnome.org/show_bug.cgi?id=760821
GstTracerValueFlags is not being initialized and the same could result in wrong
comparision and behavior. Hence initializing it to GST_TRACER_VALUE_FLAGS_NONE.

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.
We use this class to register tracer log entry metadata and build a log
template. With the log template we can serialize log data very efficiently.
This also simplifies the logging code, since that is now a simple varargs
function that is not exposing the implementation details.
Add docs for the new class and basic tests.
Remove the previous log handler.
Fixes#760267
If no providers for a particular class could be found, then removing unmatched
filters would cause all devices to be returned instead which is not at all what
the user intended. We still return 0 for unmatched filters.
Other gst libraries and/or elements may want to add some debug logging to an
external debug system or implement delayed debugging for performance reasons.
Exposes the internal __gst_vasprintf as gst_info_vasprintf which has a fallback
to g_vasprintf if the debug system is disabled.
API: gst_info_vasprintf
API: gst_info_strdup_vprintf
API: gst_info_strdup_printf

GstControlSourceGetValue() value paramater is a gdouble, not a GValue
and GstControlSourceGetValueArray doesn't return a GstValueArray but
an array of double.

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.
It's used by the debugging and tracer subsystem and in various files, make it
a central thing that is initialized independ of the existence of those
subsystems.
The parse-launch API automagically handles dynamic pads and performs delayed
linking as needed, without any feedback about whether the linking succeeded or
not however. If a delayed dynamic link can't be completed for whatever reason,
parse-launch will simply wait in case a suitable pad appears later. This may
never happen though, in which case the pipeline may just hang forever.
Try to improve this by connecting to the "no-more-pads" signal of any element
with dynamic pads and posting a warning message for the related outstanding
dynamic links when "no-more-pads" is emitted.
Fixes#760003
