Add a patch to make the pwlib library work with the new pthreads (libc_r)

library in FreeBSD 4.2 (and in -current)

Important Note: Existing binaries for OhPhone, GateKeeper, OpenGateKeeper,
SimpleH323 and OpenAM  WILL NOT WORK  with FreeBSD 4.2 or higher and will
report "User signal 2" and abort due to an unhandled signal in pwlib.
You must recompile all these applications.

Suggested fix by: Daniel M. Eischen <eischen@vigrid.com>
