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.

Fixes #760267

2f41e7bc6a tracer: harmonize the query hooks 
In post hooks always pass the return value as the last param. Pass the query
also to post hooks since it is still alive.

5e40639be7 tracer: make gst_tracing_register_hook_id static

using it.

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.

46ea9729df tracer: split into tracer and tracerutils
