Create an initial 'automake' system - only tested on Linux so far!!
+ Add Makefile.am files for all the programs we want to compile.
+ Remove all Makefiles (including the linux variants)
+ Add a autogen.sh wrapper script
+ Create the config directory with M4 macro files.
+ Remove the commands*.cfg files - autogenerated.
+ If Linux, ZONENAME is simply 'echo global' (=> always 'global' zone in Linux).
