First attempt at unifying WITH_* options

I want to voice my support for adding this type of facility to the port
system for FreeBSD. This is sorely needed.
I haven't tried the patch yet. But from a brief glance, it apppears to
be exactly what we need.
We also need a place for the port maintainer to record a summary of the
options, as well as any comment that is specific to that option and
port. For instance, if each port had a file "pkg-options", this could
WITH_TCL - Add tcl support. Currently experimental.
WITH_TK - Add tk support. Currently broken.
WITH_FOO - Add support for foo. Developers only.
