  Whoops - this patch is required by the last request.c change.

  Fulfills Brian Pane's suggestion that we always overallocate by one
  to make /foo/bar quickly convertable to /foo/bar/

  Shortcut where the resource has no language [discovered with no
  DefaultLanguage in cgi-bin, resolving Greg Ames' observations, we
  had a lurking segfault.]

  This begs the question, what exactly did the fn do with no language
  in terms of serving content back in 1.3.  Should be reviewed.

  Which PR?  I can't count them all.  Get QUERY_STRING and PATH_INFO
  working again.  Also rounds out our fix to work around negotiated
  directories which Greg Ames fixed; this addition in request.c simply
  shortcuts all further processing.

ap_rgetline()...

In the "folding" case, there was an ap_get_brigade() call after
the brigade had been destroyed.  I noticed this while debugging
a memory leak that showed up while testing the httpd with ab.

ap_add_output_filter_handle()

There are many places in the core modules where we do
ap_add_input_filter() or ap_add_output_filter() on a
hardcoded filter name (e.g., "CORE" or "BYTERANGE").
This requires a string-to-filter mapping that wastes
CPU time.  (Even though the string lookup uses a trie
for speed, it still ranks as a big consumer of CPU time
because of the large number of filters added per request.)

The new ap_add_*_filter_handle() functions will allow
us to skip the string-to-filter mapping in cases where
the module adding the filter happens to have the
ap_filter_rec_t* for the registered filter (e.g., because
it's the same module that registered the filter in the
first place).

               generally worked but with a memory debug build it could
               crash since some memory debuggers don't like an alloc of

subrequests

this function has been creating bogus subrequest URIs when there is
path_info for a long time.  They didn't matter until fixup_dir started
using them for URI subrequests, which led to a loop with ever growing
bogus internal URIs and filenames.

I haven't created the optional function to specify the cache_key yet,
That will come after this patch.

ok.. brief summary of whats changed

* new Optional Directives
	* CacheMemEntrySize -- max size of a individual entry in memory
		cache
	* CacheIgnoreNoLastMod - so we can cache mod-included files

* it tries to figure out the size of the request based on buckets if the
	content-length header isn't set

* mem_cache now caches the subprocess_env & notes tables
* the CACHE_IN/OUT/CONDITIONAL run at FTYPE_CONTENT+1, so that
	all other content filters run BEFORE the cache in.

note: the code is still experimental, and we need a bit more work
mainly...
* garbage collection
* cache stats/reporting
* manual removal of a key.

  No.  I don't like this patch.  I like what it does [shared scoreboard
  for Windows, finally] but not how it's implemented.

  However it works, and is equally crufty to what already exists for
  win32 listeners and other exposed data within scoreboard.c.

  To do this right, we need to drop all the external references to data
  within the scoreboard, and add an accessor for remaining bits (such as
  Win32's need for direct access to the apr_shm_t.)  And within Win32,
  we need to stack all this _within_ the pre-mpm hook.  But those are
  missions in and of themselves.
