  Add layout and argument parsing macros

config.layout
  Create a skeleton set of layouts for APR

build/apr_common.m4
  APR_LAYOUT: New macro to parse layouts stored in config.layout

  APR_ENABLE_LAYOUT: New macro to enable layout parsing, takes one argument
  in configure, --enable-layout=<layout>

  APR_PARSE_ARGUMENTS: New macro to allow us to reparse location handling
  arguments after setting up a layout.

Concept Obtained From: Justin, Greg
