add support to recognise uuencode file format and ingnore uu

[cnst]

In the source trees of *BSD projects, some binary files are sometimes present (e.g. font, firmware and architecture-specific files), and are often encoded with uuencode.

As it stands, this results in a lot of rubbish being indexed, and those files, once converted to xref/, contain a lot of links for random paths, as / is one of the characters of the uuencode encoding.

For bxr.su, I wrote a simple parser, that only indexes the top and the bottom portions of such files, skipping all the uuencode content.
