Subject: Completely rewrote apache.mk and apachever.mk. The latter is now an
 alias for apache.mk, since I don't see a reason why a package should query
 the apache version without also adding a dependency on apache.

Fixed the documentation to match the code. Made the code simpler. Added
sanity checks for both package-settable and user-settable variables.
