Now that the struct record holds the cpu information, there's no need
to pass the cpu number to the pevent parsing routines.

Instead of passing in the data, size and timestamp to the
pevent parsing routines, pass in the record itself. This allows
the pevent parsing routines to have a bit more control and facilitates
the need of future work where we need to know more about the record
in the parser.

Calling the event format parser "struct event" may lead
to confusion about if the struct actually represents an instance
of an event instead of what it really is: a format descriptor.

Currently pevent uses global variables to store the event types.
This will eventually bite us since we may someday want to be able
to read multiple files with different formats. This patch adds
a handle to pevent, to keep it encapsulated.

Callbacks in plugins may need to know what the timestamp was when
the trace was occurred.
This patch gives the callback its timestamp in nanoseconds.

Callbacks in plugins may need to know what cpu the trace was recorded on.
This patch gives the callback the cpu it is on.

The current hrtimer plugin code is broken wrt.
the return values, but it can now ignore the
trace_seq_* return values completely and focus
on parsing the data. Also, the handler API
should return 0 (all OK) or negative numbers
on errors.

This should make the plugin able to read data
from both 32 and 64 bit platforms regardless
of the machine it is running on.

On my machine the field is called just "timer", not "hrtimer",
so handle that (silently).
