[PATCH] updates to httpd to work with the new APR thread API

[Aaron Bannert <aa...@ebuilt.com>]

And now the updates to httpd to get it working under httpd [cross posted
to new-httpd because I'll need someone with httpd commit access to update
this once the changes to APR have been commited].


This patch is just the bare minimum to get httpd working with the
new thread API. Changes affected the threaded and perchild MPMs. I'll
revisit both of these MPMs once I have a better idea what can change to
take advantage of the new API (it looks like we are using static/global
variables to pass the parent pool around to the threads...), but for
now this keeps up to date with APR and changes no real functionality.
