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.

Add a tool to sort unordered events
...
The region of past events must be enclosed by the OU[ and OU] events and
all the events within the region must be sorted. The sorting mechanism
looks back up to 10000 events, so it may fail if they are too far away
in the past.

Remove ovni_clock_update()
...
The clock is now managed by the user, using the ovni_clock_now()
function to sample the current value and ovni_ev_set_clock() to set the
event clock timestamp. This change allows events with custom clock
values.

Early duplicate state detection in channels
...
These checks allows the emulator to abort at the moment in which two
consecutive states are going to be emitted by the channel, showing the
culpirit in the backtrace. Waiting for the check in chan_emit() hides
the source of the problem.
