timechart needs to add a "callback" type command line argument that
does not take arguments.
This patch adds the parse-options.h infrastructure to make this
possible.

There is no predefined macro to create an option that can have
a custom value or a default one if none is given.
This patch provides a new helper OPT_CALLBACK_DEFAULT() which
defines such kind of option.
For example, considering an option -c, we want to get the
default value in the following cases:
perf command -c -d
perf command -d -c
And the foo value when it's given:
perf command -c foo -d
perf command -d -c foo
That's also why PARSE_OPT_LASTARG_DEFAULT is extended here to
support default values whatever the position of the option, not
only in the end.
Should it now be renamed to PARSE_OPT_ARG_DEFAULT ?

Enable -Wextra. This found a few real bugs plus a number
of signed/unsigned type mismatches/uncleanlinesses. It
also required a few annotations
All things considered it was still worth it so lets try with
this enabled for now.

Several people have suggested that 'perf' has become a full-fledged
tool that should be moved out of Documentation/. Move it to the
(new) tools/ directory.
