[PATCH] work towards porting davautocheck.sh for httpd trunk

This is not at all a finished work, but sharing of a patch in
progress. Thought maxb or rooneg might be interested in the
interim...I'm not actively pursuing it ATM.

The wget request in davautocheck.sh which validates that httpd is
functional per the generated httpd.conf fails -- it downloads a zero
length file. I'm assuming that this is due to a mis-configuration of
httpd.conf. If you comment out the wget validation, the command-line
tests pass (all but one, last I checked).

[[[
Allow davautocheck.sh to work with httpd trunk (2.3.x) through 2.0.x.

* subversion/tests/cmdline/davautocheck.sh

  (cleanup): Renamed from trap_cleanup(), since we seem to need to
   call it explicitly from fail() too.

  (fail): Call cleanup() to assure the PID is reaped.

  (LOAD_MOD_*, ...): Find and load modules for latest revision of
   httpd's authn/authz implementation.

  (Directory $HTTP_ROOT): Add "Require all granted" directive.
]]]
