[PATCH 13/13] perf tools: Move subcommand framework and related utils to libapi

From: Josh Poimboeuf
Date: Fri Dec 04 2015 - 17:00:14 EST

The perf subcommand framework is needed for other tools. Move
parse-options.c and its dependencies over to libapi.

Any function names with 'perf' have been renamed to something more
generic.

Also created a util_cfg struct for passing perf-specific configuration
to the library. Specifying the configuration at runtime allows the same
binary to be shared by multiple tools without having to recompile it.
