[ITP] libtre5

I'd like to package and maintain the TRE library for Cygwin. TRE is a regexp
matching library, which includes unique features including approxmiate
matching. It also includes agrep, a variant of grep that does approximate line
matching.

The Cygport file is below, and in the tre branch of
https://cygwin.com/git/cygwin-packages/playground.

libtre5 is in Debian: https://packages.debian.org/sid/libtre5 .

libtre5, utf8proc, and libuninum are all dependencies of msort, which I plan
to package once all of those are released.
