tracers: set MAY_BE_LEAKED on tracer records
...
The records are static and so appear as false positives when using those
tracers with the leaks tracer as well.
The leaks tracer was already setting this flag on its record so let's
set it on the other ones as well.

tracers: Allow setting a name for all tracer objects
...
This will be useful in combination with the next commit when we add
API to get a list of active tracers so that consumers of the API can
easily distinguish tracer objects.

gstrusage: explicitly register to hooks

We were attaching to any probe point to take rusage samples. The new refcount

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.

rusage: properly free the queue memory

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.

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.

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.
