*) mod_authz_core: Allow authz providers to check args while reading the
config and allow to cache parsed args. Move 'all' and 'env' authz
providers from mod_authz_host to mod_authz_core. Add 'method' authz
provider depending on the HTTP method. [Stefan Fritsch]
*) mod_include: Move the request_rec within mod_include to be
exposed within include_ctx_t. [Graham Leggett]
*) mod_include: Reinstate support for UTF-8 character sets by allowing a
variable being echoed or set to be decoded and then encoded as separate
steps. PR47686 [Graham Leggett]
*) mod_cache: Add a discrete commit_entity() provider function within the
mod_cache provider interface which is called to indicate to the
provider that caching is complete, giving the provider the opportunity
to commit temporary files permanently to the cache in an atomic
fashion. Replace the inconsistent use of error cleanups with a formal
set of pool cleanups attached to a subpool, which is destroyed on error.
[Graham Leggett]
*) mod_cache: Change the signature of the store_body() provider function
within the mod_cache provider interface to support an "in" brigade
and an "out" brigade instead of just a single input brigade. This
gives a cache provider the option to consume only part of the brigade
passed to it, rather than the whole brigade as was required before.
This fixes an out of memory and a request timeout condition that would
occur when the original document was a large file. Introduce
CacheReadSize and CacheReadTime directives to mod_disk_cache to control
the amount of data to attempt to cache at a time. [Graham Leggett]

attack when compiled against OpenSSL version 0.9.8m or later. Introduces
