Modified the cache code to be header-location agnostic. Also
  fixed a number of other cache code bugs related to PR 15852.
  Includes a patch submitted by Sushma Rai <rsushma@novell.com>.
  This fixes mod_mem_cache but not mod_disk_cache yet so I'm not
  closing the PR since that is what they are using. [Paul J. Reder]

  Simplify includes - we always (in HTTPD 2.1 forward) are looking
  for the openssl/foo.h headers explicitly.  Fix the abs.dsp build
  to define HAVE_OPENSSL instead of USE_SSL so the correct headers

- check more exactly whether the previous token is correct
- flip the tree from left-weighted to right-weighted, which is
  more natural and more efficient, since we don't need to loop
  up to the root, but just until the next and/or token.
- that way, flip the short circuit evaluation again to cut
  the right side now if possible...

result of the enclosed expression. Since this expression will never
touched again during the tree-building stage, we can safely strip
TOKEN_GROUP from the tree and later evaluate the child directly.

The only side effect of this change is, that grouped strings on the
left side of EQ/NE/etc are now allowed (was invalid before), which
is acceptable IMHO (e.g. (foo bar baz) = zzzip)

- the left side of such an operator can *only* be a string
- get a rid of the while-loop and re-organize the code
  to better reflect what we're actually doing there

is way more useful if we short circuit the left side. So evaluate
the right side first. This, however, reverses my statement about
regex optimization (you have to put them onto the right side of an
&& or || operator to get a chance that the left side will be cutted).
