Add a port for 'tre', an LGPL'ed regex library. From the port's

description:

  TRE is a lightweight, robust, and efficient POSIX compliant regexp
  matching library supporting:
   - approximate (fuzzy) matching,
   - strict standards conformance,
   - predicable and modest memory consumption,
   - wide-character and multibyte character support,
   - binary pattern and data support,
   - thread-safe implementation.

  At the core of TRE is a new algorithm for regular expression matching
  with submatch addressing. The algorithm uses linear worst-case time
  in the length of the text being searched, and quadratic worst-case
  time in the length of the used regular expression.
