Apache2 patch sanity check

This patch is to fix http://bugs.php.net/33690 which is caused by the
fact that php_handler() in sapi/apache2handler/sapi_apache.c calls
apply_config() well before it has allocated SG(server_context) and set
ctx->r to the current request_rec. Downstream from that any ini handler
that needs something from SG(server_context) is thus out of luck.
Following the chain up the backtrace in bug #33690 should make that very
clear if you didn't follow my bad explanation.

So, this patch simply moves the allocation of the context up before the
call to apply_config(). It's not my sapi, and I still don't run Apache2
in anger anywhere, so I'd appreciate a quick sanity check.
