UTF-7 sample implementation

I now consider the definition of UTF-7 stable, and I've submitted the spec
to the RFC editor. I'm now posting a sample implementation that people can
use if they want to implement UTF-7. This code is based on code I added to
plan 9's tcs tool to support UTF-7.

I will also be posting this code to some Usenet newsgroups, and I would
like to place it on the unicode.org anonymous FTP server.
