Fix the configure process. This does a couple of things to allow APR and

Apache to share information.

1)  Move the calling of APR after Apache decides which MPM is run, but
    before Apache generates the Makefiles and related files.  This allows
    Apache to setup the threading cache values, while still allowing APR
    to generate APRVARS in time for Apache to use it.

2)  Setup the cache files correctly for RUN_NOW configured subdirectories.
