Set MaxMemFree 2048 by default

Fix assertion failure during very high load by preventing race condition
between appending to the timeout queues and adding to the pollset. We don't
add additional locking calls but only extend the present calls to include the
apr_pollset_add. Therefore this hopefully should not cause too much performance
regression.

Add some comments 

Replace two AP_DEBUG_ASSERTS with better error handling

1) Promoted from "most" to "yes/few"

- mod_headers

2) Demoted from "yes/few" to "most"

- mod_actions
- mod_allowmethods
- mod_auth_form
- mod_buffer
- mod_cgi(d)
- mod_include
- mod_negotiation
- mod_ratelimit
- mod_request
- mod_userdir

Remember: default module set is "most",
but only the LoadModule lines of all
modules except "yes/few" are commented out by default.

The following modules will now be loaded by default:

- mod_access_compat
- mod_alias
- mod_auth_basic
- mod_authn_core
- mod_authn_file
- mod_authz_core
- mod_authz_groupfile
- mod_authz_host
- mod_authz_user
- mod_autoindex
- mod_dir
- mod_env
- mod_filter
- mod_headers
- mod_log_config
- mod_mime
- mod_mpm_event
- mod_reqtimeout
- mod_setenvif
- mod_status

fix issue with incorrect munging of the lua package path -- LuaPackagePath directives were not working

Default to not allowing htaccess in /, instead of just the documentroot, which gets a nice 10% performance boost by default for me.

* modules/ssl/ssl_private.h, modules/ssl/ssl_engine_kernel.c
  (ssl_callback_tlsext_tickets): Use unsigned char * to fix gcc
  -Wpointer-sign warnings.


Only load the really imporant modules (i.e. those enabled by the 'few'
selection) by default. Don't handle modules enabled with --enable-foo
specially.

This fixes problems with module dependencies until someone implements a
mechanism for resolving module dependencies.


remove last traces of the code cache

* modules/proxy/mod_proxy_html.c (comp_urlmap): Fix const-ness warning.


* modules/lua/mod_lua.c (ap_lua_ssl_is_https): New function.
  (lua_post_config): Pick up ssl_is_https optional function.

* modules/lua/lua_request.c (req_ssl_is_https_field): New function.
  (ap_lua_load_request): Map is_https field to above.
