[jo...@apache.org]

Author: jorton

New Revision: 1884208

URL: http://svn.apache.org/viewvc?rev=1884208&view=rev
Log:
Rearrange and clear global core config state allocated out of pconf
from a single cleanup:

* server/core.c (reset_config): Clear ap_runtime_dir here, rather than
  in register_hooks.
