A new trace-cmd subcommand is introduced:
 trace-cmd convert -i <input file> -o <output file>
The command converts trace file between different versions. There are two
parameters for controlling the type of the output file:
 --file-version < 6 / 7>
 --compression < none / any / name of the desired compression algorithm >

This patch-set depends on:
 "[PATCH v6 00/20] Trace file version 7 - compression"
 https://lore.kernel.org/linux-trace-devel/20211210105938.98250-1-tz.stoyanov@gmail.com/
 
v6 changes:
 - Rebased on top of the latest master.
