A plugin may only need to translate part of the field, or if it fails to
translate, it may want the default to print.
Now if a plugin handler returns something other than 0, the default print
handler will take place.

With the new page ref counts, there's no need for the
tracecmd_refresh_record() call. We'll keep it around, but it is
now labeled as obsolete.

The function graph tracer looks forward in the trace to determine
if a function is a leaf or not. In doing so, it causes the mapping
of records to change. This produces a nasty side effect where the
caller can have the record stored, and it will suddenly invalidate
the record's mapping.
This refreshes the record passed in and does a trick by calling
the tracecmd_peek_data function that will cache the location
after the leaf function's return entry.
This unfortunately causes a side effect too where if the last
entry in the trace is a leaf function, we can't hide the exit entry
and it will print regardless. But this side effect wont crash the
application, but the previous side effect will.

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.

We will soon be adding write functionality to the tracecmd
library. This will require a new and separate handle than what
is used by the file reader.
"handle" is too generic. Rename it to "input" so we can make
the output handle called tracecmd_output.

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.

The data for the events in the output looks better if most of them
are lined up in a column.

The trace_read_data and trace_peek_data() required a global file
descriptor for reading. This was kept because the library libparsevent
had the function graph tracer implementation and required a callback
to read. This code has been moved out of parse_events.c and into a
special override function.
Now it still uses the global read, but since libtracecmd has a little more
scope than libparsevent, we added a thread variable
tracecmd_curr_thread_handle
This is unique per thread, and is set right after data is read.
Yes there are some races, but we can deal with it for now.

The function graph tracer is a special case in libparsevent.
It is also the reason for the work arounds in tracecmd with the
callback to trace_read_data() and trace_peek_data().
This patch moves the function graph tracer as a override and out
of the libparsevent.

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 libparsevent currently does special cases for the function tracer.
This patch replaces the special case with a event override. This is
loaded by libtracecmd.
