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@redhat.com

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

When building perf binaries outside the source tree with 'make O=<dir>',
the auto-detected features get re-tested for every build, which is
unnecessary and inconsistent with the behavior seen when building
directly in the source tree.

Another issue is that 'make O=<dir> clean' doesn't remove the feature
files from the object tree.

Fix these problems by looking for the binaries in the $(OUTPUT)
directory.

strlcpy() will be needed by the subcmd library.  Move it to the shared
tools/lib/string.c file which can be used by other tools.

Generally, calling exit() from a library is bad practice.  Eventually
these functions might be redesigned so that they don't exit.  For now,
just document the fact that they do.

Create init functions for exec_cmd.c and pager.c.  This allows their
configuration to be specified at runtime so they can be split out into a
separate library which can be used by other programs.  Their
configuration is stored in a shared subcmd_config struct.

Introduce and use new astrcat() and astrcatf() functions which replace
the strbuf functionality for subcmd.

For now they duplicate strbuf's die-on-allocation-error policy.

Move the subcommand-related files from perf to a new library named
libsubcmd.a.

Since we're moving files anyway, go ahead and rename 'exec_cmd.*' to
'exec-cmd.*' to be consistent with the naming of all the other files.

Here's the same patch but without the unnecessary addition of the
<linux/types.h> include.  Ideally it would be folded into

  "perf tools: Finalize subcmd independence"

but in case it's too late for that, I added a changelog.
 
---8<---

Subject: [PATCH] tools subcmd: Fix 'u64' build error with older compilers

Arnaldo reported the following error when building perf on RHEL 6.7:

  parse-options.c:15: error: redefinition of typedef ‘u64’
  /home/acme/git/linux/tools/include/linux/types.h:28: note: previous declaration of ‘u64’ was here

The parse-options.c file includes <linux/compiler.h>, which includes
<linux/types.h>, which has a u64 typedef.  So the u64 typedef in
parse-options.c is unnecessary (and seems to trigger the above error on
compilers which don't allow duplicate typedefs).

tools build: Fix feature Makefile issues with 'O='

When building perf binaries outside the source tree with 'make O=<dir>',
the auto-detected features get re-tested for every build, which is
unnecessary and inconsistent with the behavior seen when building
directly in the source tree.

Another issue is that 'make O=<dir> clean' doesn't remove the feature
files from the object tree.

Fix these problems by looking for the binaries in the $(OUTPUT)
directory.

perf tools: Move strlcpy() from perf to tools/lib/string.c

strlcpy() will be needed by the subcmd library.  Move it to the shared
tools/lib/string.c file which can be used by other tools.

perf tools: Document the fact that parse_options*() may exit

Generally, calling exit() from a library is bad practice.  Eventually
these functions might be redesigned so that they don't exit.  For now,
just document the fact that they do.

perf tools: Provide subcmd configuration at runtime

Create init functions for exec_cmd.c and pager.c.  This allows their
configuration to be specified at runtime so they can be split out into a
separate library which can be used by other programs.  Their
configuration is stored in a shared subcmd_config struct.

perf tools: Remove subcmd dependencies on strbuf

Introduce and use new astrcat() and astrcatf() functions which replace
the strbuf functionality for subcmd.

For now they duplicate strbuf's die-on-allocation-error policy.

perf subcmd: Create subcmd library

Move the subcommand-related files from perf to a new library named
libsubcmd.a.

Since we're moving files anyway, go ahead and rename 'exec_cmd.*' to
'exec-cmd.*' to be consistent with the naming of all the other files.
