Recursing into ignored dirs for diff and status

This implements working versions of GIT_DIFF_RECURSE_IGNORED_DIRS
and GIT_STATUS_OPT_RECURSE_IGNORED_DIRS along with some tests for
the newly available behaviors.  This is not turned on by default
for status, but can be accessed via the options to the extended
version of the command.
