Add kernel support for context switch events
...
These events only show if a thread has been removed from the CPU, but
doesn't provide information about what other thread caused the context
switch. This type of information can be obtained even with strict
/proc/sys/kernel/perf_event_paranoid settings.

Use priority queue for streams and fast channels
...
A priority queue (in heap.h) is used to keep the next event ready in the
emulator loop. Additionally, a list of dirty channels is keept to
limit the complexity of the propagation and emit phases.
