This is the start of code to allow kernelshark to be used to capture data.
This patch also introduced threaded tasks in reading the trace-cmd output.

The internal filter dialogs currently pass around the tracecmd_handle,
but only uses the pevent to display the data. Pass pevent around
instead. This also allows us to add:
trace_filter_pevent_dialog()
This function will display a event dialog with a pevent being
passed to it instead of a tracecmd_input handle. Now we can
pop up the events local to the system that are not related to
any file.

The latency tracer plugins do not support network tracing. It crashes
when an attempt to do a latency tracer plugin with the -N option.
Simply prevent trace-cmd from performing a network trace with one
of the latency tracer plugins and update the man pages.

The change back to returning unreferenced records from tracecmd_peek_data
may have broken python applications using it, just like it would have
broken C applications.
In order to avoid issues with it, provide real python API for using it,
using a new tracecmd_peek_data_ref() API function.

Move the filters around so that the graph filters
are all together, and the list filters are all together.
This makes accessing the filters a bit easier when they

The clear_task_menu was being updated by the set_menu_label()
helper function. But that function expects a "comm" passed to it.
The clear_task_menu may be updated when comm is NULL, and this would
cause a strlen(comm) to crash the program.
