Only minor adjustments were required to support 2.4.x too, so
look at AP_SERVER_MINORVERSION_NUMBER and adjust the lists of
available modules and libhttpd sources.

The build already worked with apr/aprutil 1.x, so adjust the
doc, defaults, and todo list.

The --with-module equivalent is already done, so zap the todo.
