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.

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.

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.

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.

Yes, and it continues to build on fedora 21.

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).

perf tools: Finalize subcmd independence
For the files that will be moved to the subcmd library, remove all their
perf-specific includes and duplicate any needed functionality.

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.

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.
