- (bal) Reorder. Move all bsd-*, fake-*, next-*, and cygwin* stuff to

   openbsd-compat/.  And resolve all ./configure and Makefile.in issues
   assocated.

Logic:

* All OpenBSD functions should have the same filename as in the OpenBSD
  tree

* All 'home brew' functions have bsd-* infront of them.

* All 'not really implemented' functions have fake-* infront of them.
