tracer: add a GFlag for the tracer scope
...
Port all tracers. Add the GST_USE_UNSTABLE_API flag to the internal CFLAGS so

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

for the global state.

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.

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.

The MessageId is more detailed and anyway needed to interpret the varargs.
