parser: construct alias object by rule-set class

It was odd that the revsetalias did the whole parsing stuff in __init__().
Instead, this patch adds a factory function to the aliasrules class, and
makes the alias (= revsetalias) class a plain-old value object.

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)
