If a request contains both a T-E and C-L, remove the C-L, stopping some HTTP Request Smuggling attacks exploited when using HTTPD as a forward or reverse proxy.

I will be adding documentation for the new directives hopefully in the next day or so.

* server/core.c: Added 'Protocol' to the core module config
                 Added ap_{set,get}_server_protocol API.
                 Added new directive: 'AcceptFilter'.
                 Enable 'httpready' by default on systems that support it.  Use dataready filters for others.

* server/listen.c: Attempt to inherit protocols from Listener Records to Server configs.
                   The 'Listen' directive can now optionally take a protocol arg
                   Move bits that determined which accept filter is applied to core.c.
                   Added bits to find the correct accept filter based on the core's configuration.

* include/{ap_listen.h,http_core.h}: Add Protocol to respective structures.

* include/http_core.h: Add the accf_map table to the core_server_config structure

* include/ap_mmn.h: Minor MMN Bump for the new interfacces.

* modules/ssl/ssl_engine_init.c: Use the new protocol framework to enable mod_ssl for 'https' websites.

- Bring htcacheclean into sync with mod_disk_cache.  It now has a very basic understanding of the Varied Headers file format, and will cleanup orphaned data files, or Vary Header Files that have expired.

* cache/mod_disk_cache.c: Make most members of disk_cache_object into const char*. This removes the need to cast the const out in several places.
* cache/mod_cache.h: Make cache_object.key a const.

These Vary headers are used to build a new hash for a URL, based on the 
client's headers.  This allows mod_disk_cache to store many variations of one 
URI, where previously it would only store a single variant.

htcacheclean needs to be updated to understand the new file format.  I plan on 
updating htcacheclean in the next couple days.

Don't use AC_PROG_INSTALL since any system "install" command is never
used anyway.

* build/rules.mk.in: Remove fixed reference to install.sh and mkdir.sh
in abs_srcdir.

* build/config_vars.sh: Munge definitions of MKINSTALLDIRS and INSTALL
to use installed scripts.

build and source directories, and to remove variables which are
internal to the httpd build system:

* build/config_vars.sh.in: New file.

* Makefile.in (build/config_vars.out): New target.
(install-build): Install build/config_vars.out as config_vars.mk.

* configure.in: Add include path for srclib/pcre to INCLUDES rather
than CPPFLAGS, and use a topdir-relative not absolute path name.
Generate build/config_vars.sh.
