*) Add logging of failures for a provider's store_body function.

* modules/cache/mod_cache.c
(cache_save_filter): Instead of unconditionally returning a 304 when
the original request was conditional and we issued a cache revalidating
request, handle the request as if it came in while our cache was
still valid.
* modules/cache/cache_storage.c
(cache_select_url): Strip off the conditional headers from the original
request, prior to adding our own for the purpose of revalidating our
cached response.

* modules/cache/mod_cache.c: If we add a new Expires value, tell our client;
merge in headers properly (or better than before) so that we can update the
header fields on a revalidated but with updated header fields.
* modules/cache/mod_cache.h, modules/cache/cache_storage.c:
Add preserve_orig flag to ap_cache_accept_headers to allow updating of fields.

ap_cache_accept_headers.

Saves certain people a bit of time figuring out why their caching
doesn't work...
* modules/cache/mod_cache.c
(add_cache_enable): Throw an error when a provider starting with
a '/' is encountered. The user probably switched arguments.

CacheIgnoreCacheControl and add documentation for two new directives.

Also, take quick pass through docs files to remove experimental label for them.
