Add an allocator-passing mechanism throughout the bucket brigades API.
From Apache's standpoint, the apr_bucket_alloc_t* used throughout a given
connection is stored in the conn_rec by the create_connection hook. That
means it's the MPM's job to optimize recycling of apr_bucket_alloc_t's --
the MPM must ensure that no two threads can ever use the same one at the
same time, for instance.

reference counting. Enabled by default via the USE_ATOMICS preproc directive.
This compiles cleanly and serves pages on Windows. Not compiled or tested on
any other OS.

obj was set before the mutex so someone could have came and updated h->cache_obj
between us setting obj, and useing it.
running now for 10 minutes without core (a record!)

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.

add remove_entity function to type on mem_cache (so we can remove items from the cache)

is common across any cache implementation, the other part is private to
the particular implementation (eg, mem_cache_object_t/mod_mem_cache).
Use a cache_handle_t allocated out of the request pool to hold references
to the callback functions and common cache object.
The cache_handle_t contains implementation specific callback functions and
a reference to a common cache_object_t. The cache_object_t contains
a reference to an implementation specific cache object extension (mem_cache_object_t
for example).
All this simplifies managing the callback function pointers (don't want to
save them in each cache entry) and collections of cache_object_t keyed
to a single url.

1. Change CACHE_TYPE_MALLOC to CACHE_TYPE_HEAP
2. Enable cacheing content contained in multiple brigades
3. Don't cache an entry more than once.

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 :-)
