Add two new OPTIONS to this port:

- The PCRE option allows one to link pound against libpcre for the regcomp()
  and regexec() functions instead of libc.  This can make a substantial
  difference in CPU consumption with some workloads.  Defaults to off.
- The LIBTHR option links pound against the libthr for threading, instead
  of libpthread.  This makes a *huge* difference when you deal with enough
  traffic.  Defaults to on.

Bump PORTREVISION.
