revrange: drop old-style parser in favor of revset (API)

Now revset can parse nullary ":" operator and existing "foo+bar" tags, we
don't need the old-style parser.

This means scmutil.revsingle(), revpair() and revrange() no longer accept
a binary nodeid. An integer revision is still allowed as it isn't ambiguous.

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)
