  Rather than continuing to canonicalize within directory_walk (very time
  consuming on all but *nix systems) we temporarily canonicalize to compare
  the results of the many merges, and fail on a mismatch.

  The apr_filepath_merge and ap_server_root_relative calls now merge the
  file _by canonicalizing it_.  That includes resolving all /../, /./,
  and // misnomers.

  A minor effort is required to figure out who all munges the r->filename
  in an inappropriate manner.

  The final (return to optimized state) probably involves setting an
  r->goodname argument to r->filename, every time we properly merge
  through ap_server_root_relative or apr_filepath_merge().

  Overhauled ap_server_root_relative, so that it now changes any path
  to canonical form through apr.  Also assures that a change to the
  ServerRoot through a -C option takes effect before locating the

  Eliminated ap_os_[systemcase|[case_]canonical]_filename() and
  move ap_os_is_path_absolute() into util.c (now relies on apr.)

  Canonicalization will now occur on all sub_req_lookup_file() calls,
  and the ap_server_root_relative() will handle canonicalization as well.

  ap_server_root_relative will take care of this canonical_file call.

  Performance death notices.  Note that we shouldn't have EVER coded a
  module with a fixed path ... the config phase should take the proxy/
  path and ap_server_root_relative() it at startup.


git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@90564 13f79535-47bb-0310-9956-ffa450edef68

  Optimize out what is a very expensive in-request call to
  ap_server_root_relative (and is becoming more expensive).
  Now the call happens in the config phase where it belongs.
  Note someone can hop in and transpose the stat and open
  with an open and getfileinfo if you are a performance hound.

  This was copied as a test of the ap_r[put|putc|write|printf] family of
  functions.  Since those don't seem to be going anywhere, this test is
  redundant and a maintance headache.

Fix for mod_include. Ryan's patch to check error
codes put a return in the wrong place. Also, the
include handler return code wasn't being checked.
I don't like macros with returns, so I converted
SPLIT_AND_PASS_PRETAG_BUCKETS into a function.

implements a quick handler, and three filters. The filters are
CACHE_IN for loading the cache, CACHE_OUT for serving content out of the cache
and CACHE_CONDITIONAL, which handles stale entries in the cache.

mod_cache implements code that makes RFC compliant caching decisions. It
interfaces with the actual storage mechanism via calls to functions defined in
cache_storage.c.  This commit includes a simple in memory (malloc'ed memory)
cache implementation that demonstrates autoloading and serving files
keyed on URL.

This is not even close to production ready. You have been warned :-)
