This change will support stage2 running LAR files. The initial example

Browse source 
is running the VSA in the geode lx northbridge.

It builds but is not tested.

lar.h: make LAR functions SHARED
lar.c: make process_file non-static (i.e. global)
vsmsetup.c: modify to use LAR functions.
stage1.c: new function, init_archive, which is SHARED and will set up
the initial archive struct.

Note that some work remains. The use of unsigned longs and unsigned
shorts should be changed to u32/u16 as Carl-Daniel has pointed out,
Because this change requires changes elsewhere I am not including them
in this patch.
