82c1ec4931 tracer: add element-change-state-pre/post hook
Helps catching when a state change is starting and ending.

It is also possible to track the end of state changes by checking the
async-done or state-change messages.
This is particularly important for elements that do async state changes.

This makes it more obvious what is the api for tracer elements and what is api
for the global state.

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
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.
