Turn the cache module into first class citizens (well the disk_cache
and file cache that is).

This makes the delta between 'all' and 'most'

mod_cern_meta.c
mod_log_forensic.c
mod_mime_magic.c
mod_unique_id.c
mod_usertrack.c
mod_version.c
mod_mem_cache.c

And keeps disabled in all and most the modules for:

authnz_ldap
bucketeer
echo
example_hooks
case_filter
case_filter_in
example_ipc
charset_lite
cgid
ldap
optional_hook_export
optional_hook_import
optional_fn_import
optional_fn_export

As well as mod_ssl which is intentionally not part of MOST and All.
