tracer: make gst_tracing_register_hook_id static
...
We don't need to expose this as public API. Change the only plugin that was
using it.

tracing: rename the global api to gst_tracing
...
This makes it more obvious what is the api for tracer elements and what is api
for the global state.

tracers: eliminate var_args
...
Register tracer hooks as GCallback. Use macros for hook dispatch and cast the
hook functions back to the appropriate type.

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.

tracer: drop the HookId hid from the invoke method
...
The MessageId is more detailed and anyway needed to interpret the varargs.

tracer: split into tracer and tracerutils
...
Keep tracer base class in tracer and move core support into the utils module.
Add a unstable-api guard to the tracer.h so that external modules would need to
acknowledge the status by setting GST_USE_UNSTABLE_API.

tracer: use macros for hooks
...
Wrap the hook with a pre and post macro. This looks less intrusive than the
previous version, although it is a little less optimized.
