[PATCH v5 00/25] Trace file version 7 - sections

["Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>]

Introduce the next version of the trace-cmd trace file - 7. Major changes
since version 6 is more flexible extendable structure of the file, based on
independent sections.
Known issues:
 - Only trace-cmd record and report subcommands work with trace file v7.

This patch-set depends on:
 "trace-cmd fixes and clean-ups" patch set.
 "Refactor APIs for creating output handler" patch set.
 "Refactor the logic for writing trace data in the file" patch set.

v5 changes:
 - Rebased on top of the latest master.
v4 changes:
 - Rebased on top of the latest master.
v3 changes:
 - Fixed issues of split and convert commands with some corner cases.
v2 changes:
 - Code cleanups.
