Mathieu Desnoyers [Sat, 21 May 2011 01:33:54 +0000 (21:33 -0400)] 
LTTng performance monitoring counters integration (work in progress)
Integrate with Perf counters. Adds context fields to the events
recorded. Currently, cpu hotplug is still not supported, and the
callbacks are not called from the tracing code. It gives the rough idea
how to add context fields to events on either:
- per trace session
- per stream class
- per event type

Fix teardown deadlock
Don't wait on the readers from the session teardown anymore, because if
the only thread that can complete reading the buffer is the same waiting
on this condition, it deadlocks.
If the session daemon needs to wait on consumers, it can always do that
in user-space through some other mechanism.
