Make git-clean a builtin

This replaces git-clean.sh with builtin-clean.c, and moves
git-clean.sh to the examples.

This also introduces a change in behavior when removing directories
explicitly specified as a path.  For example currently:

1. When dir has only untracked files, these two behave differently:

    $ git clean -n dir
    $ git clean -n dir/

the former says "Would not remove dir/", while the latter would say
"Would remove dir/untracked" for all paths under it, but not the
directory itself.

With -d, the former would stop refusing, however since the user
explicitly asked to remove the directory the -d is no longer required.

2. When there are more parameters:

    $ git clean -n dir foo
    $ git clean -n dir/ foo

both cases refuse to remove dir/ unless -d is specified.  Once again
since both cases requested to remove dir the -d is no longer required.

Thanks to Johannes Schindelin for the conversion to using the
parse-options API.
