commands: support consuming stream clone bundles

For the same reasons that we don't produce stream clone bundles with `hg
bundle`, we don't support consuming stream clone bundles with `hg
unbundle`. We introduce a complementary debug command for applying
stream clone bundles. This command is mostly to facilitate testing.
Although it may be used to manually apply stream clone bundles until a
more formal mechanism is (possibly) adopted.

#!/usr/bin/env python

import errno, os, sys

for f in sys.argv[1:]:
    try:
        print f, '->', os.readlink(f)
    except OSError as err:
        if err.errno != errno.EINVAL:
            raise
        print f, 'not a symlink'

sys.exit(0)
