Add new non-default debugging module mod_log_debug It allows to log custom debug messages at various phases in the request processing and is the first consumer of the new string-valued ap_expr API.

Add to modules' help text (displayed by ./configure -h) more information that will be useful in deciding whether to enable them or not.

Always make mod_*.h files available where they exist, modpath by modpath

* modules/loggers/config.m4: Fix --enable-mods-shared=all case where $enable_log_forensic gets set to the empty string.

* modules/loggers/config.m4: Add 'server' directory to include path if mod_log_forensic is enabled.

Add forensic logging.

Let mod_logio be mostly included. Submitted by: Astrid Ke�ler

Rename the module structures so that the exported symbol matches the file name, and it is easier to automate the installation process (generating LoadModule directives from the module filenames). Next step is to remove the 4th argument to the APACHE_MODULE macro completely and require people to use the matching names, and to reduce the LoadModule directive to 1 argument.... Objections?

*) remove STANDARD_LIBS line; it is unused/unneeded *) simplify by removing the extra AC_DEFUN() in each file

Get Apache to configure completely again. This still doesn't build, but now we are getting very close.

Get the modules configuration stuff working correctly. This just deals with STANDARD modules and Protocol, not MPMs.
