cacheflush doesn't exist on LP64 any more, and gcc's
__builtin___clear_cache is better in every way.  Use it instead.

Wrap the call in a if (0) when verbose logging is disabled
to provide compile time checking.

Also add a printf format attribute to the function to warn
if parameters are incorrect.

Extend the libselinux restorecon implementation to allow reuse
by the toolbox restorecon command.  This simply requires adding
support for the nochange (-n) and verbose (-v) options to the
libselinux functions and rewriting the toolbox restorecon command
to use the libselinux functions.   Also add a force (-F) option to
support forcing a restorecon_recursive even if the restorecon_last
attribute matches the current file_contexts hash so that we can
continue to force a restorecon via the toolbox command for testing
or when we know something else has changed (e.g. for when we support
relabeling /data/data and package information has changed).
