ede686c39b tracer/rusage: fix format string args
The format string contains a process id, but we did not provice one. This
caused us to log garbage since all args got shifted.

714ea37282 tracers: leaks: update type filter later for unknown types
This allow us to filter using an object type which is implemented
by a plugin like, say, GstGtkGLSink.

1ed4140d00 leaks tracer: use G_OS_UNIX to check for signal support
Checking for signal.h is not good enough as it's present in Windows.
Those signals are UNIX specific anyway.

6446a1a45c tracers: leaks: some micro-optimisations
- we know number of filter items is not going to change,
  but compiler doesn't

- only do GST_IS_TRACER check for GObjects, not mini objects

- use non-type check cast macros in performance critical paths

ec75b68984 tracerrecord: don't leak the spec structures
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.

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

10b78d872b tracerrecord: add a log record class
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.

4881d1c16c tracer: use GQuark or strings for the hook id
This way one can define new tracing probes without changing the core. We are
