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.
