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 "[PATCH v3 00/21] trace-cmd fixes and clean-ups",
should be applied on top of it:
  https://lore.kernel.org/linux-trace-devel/20210914131232.3964615-1-tz.stoyanov@gmail.com/

v3 changes:
 - fixed issues of split and convert commands with some corner cases
v2 changes:
 - code cleanups
