Mark Johnston 5d49283f88 pf: Make tag hashing more robust 
tagname2tag() hashes the tag name before truncating it to 63 characters.
tag_unref() removes the tag from the name hash by computing the hash
over the truncated name.  Ensure that both operations compute the same
hash for a given tag.

The larger issue is a lack of string validation in pf(4) ioctl handlers.
This is intended to be fixed with some future work, but an extra safety
belt in tagname2hashindex() is worthwhile regardless.
