Begin to sanitize the MPM configuration directives. Now, all

MPMs use the same functions for all common MPM directives.  This
should make it easier to catch all bugs in these directives once.

Everybody should check their favorite MPM to ensure that it still
compiles, and that these directives work.  This is a big patch, and
although it looks good, and things compiled for me, that is no
garauntee that it will work on all platforms.  :-)
