Request: mod_macro support.

[apenney]

This is a complicated one, I imagine, but we currently rely heavily on mod_macro for our configuration, and while I could mess around trying to write scripts to expand all the existing macros into real entries, it's really useful to be able to handle things this way. For example, we handle ldap auths on pages like:

<Location "/blah">
Use AuthBlockFilterPeople "(ou=ITS)"
</Location>

And that macro then expands to the AuthLDAPBindDN, password, options etc in the background. Without this our configuration would be enormously bloated, just for LDAP stuff.

I'd like to evaluate litespeed as a replacement, but there's no way I can easily replace all our horrible macros!
