apu_version mess

[Paul Querna]

To resolve the problems we have with calling apu_version from httpd, we 
have three main options:

[ ] Remove the new code that outputted the versions.
[ ] Make the code only present on systems that didn't have a broken build.
[ ] Wait for APR-Util 1.2.7 to be released.
Votes/Thoughts?

All of the options pretty much mean scraping the 2.2.1 release, and 
moving on to 2.2.2.

Thanks,

Paul
