Lluís Vilanova 1dad2ce973 trace: [tracetool] Minimize the amount of per-backend code
Backends now only contain the essential backend-specific code, and most of the work is moved to frontend code.

Mohamad Gebai 9530570fa5 Modified the tracetool framework for LTTng 2.x
* A new format is required to generate definitions for ust tracepoints.
  Files ust_events_h.py and ust_events_c.py define common macros, while
  new function ust_events_h in events.py does the actual definition of
  each tracepoint.
* ust.py generates the new interface for calling userspace tracepoints
  with LTTng 2.x, replacing trace_name(args) to tracepoint(name, args).
* As explained in ust_events_c.py, -Wredundant-decls gives a warning
  when compiling with gcc 4.7 or older. This is specific to lttng-ust so
  for now use a pragma clause to avoid getting a warning.

Lluís Vilanova 93fba1618d trace: [tracetool] Explicitly identify public backends
Public backends are those printed by "--list-backends" and thus considered valid
by the configure script.
