Split definitions for md5.c out of crypt.h and into their own header

libpq/md5.h, so that there's a clear separation between backend-only
definitions and shared frontend/backend definitions.  (Turns out this
is reversing a bad decision from some years ago...)  Fix up references
to crypt.h as needed.  I looked into moving the code into src/port, but
the headers in src/include/libpq are sufficiently intertwined that it
seems more work than it's worth to do that.
