Ingo suggested that I factor out the perf subcommand functionality
(originally copied from git) into tools/lib so that it can be used by
stacktool[*] and possibly others.

All the subcommand option handling files have been moved into a new
library named libsubcmd.a, including parse-options.c, run-command.c,
exec_cmd.c, help.c, usage.c, and pager.c.

Patch 1 is a cleanup I discovered in the process of making the patch
set. It's completely separate from the rest of the patches and can be
merged independently.

Patches 2-7 are some cleanups and splitting up of the code related to
the creation of the new library.

Patch 8 does the actual moving of the files and creation of the new
libsubcmd.a library in tools/lib/subcmd.

Patch 9 updates the names of the ifdef include guards for the moved .h
files.

Based on acme/perf/core.

These patches can also be found in the 'perf-subcmd-v4' branch in the
following repo:

https://github.com/jpoimboe/linux

[*] https://lkml.kernel.org/r/cover.1445443144.git.jpoimboe@xxxxxxxxxx

v4:
- Rebase onto latest acme/perf/core
- Reuse FILES variable instead of creating OUTPUT_FILES in feature
Makefile
- Make changelogs more verbose
- Move strlcpy() to tools/lib/string.c
- Create shared subcmd_config struct in subcmd-config.c

v3:
- Remove dependencies on util.h, cache.h, abspath, ctype, strbuf, term,
usage, wrapper
- Move to a new 'libsubcmd' library in tools/lib/subcmd
- Rebase onto Namhyung's patches which remove the browser dependency
from parse-options.c
- Get rid of the util_cfg struct in favor of file-specific init
functions
- Split up the patches better
- Document the fact that parse_options*() can exit
- Convert parse-options.c internal functions to static
- Rename exec_cmd.* to exec-cmd.*
- Add new astrcat() and astrcatf() functions to replace strbuf
- Add some more fixes related to 'make O=' and 'make clean' (though
a 'make clean' is no longer required and these patches are now
unrelated to libsubcmd)

v2:
- Fix 'make clean' to remove tests/llvm-src-*.c and other leftover
files
- Fix description for second-to-last patch
