This patch adds a library with a small collection of helper functions
to parse and load elf binaries.  The library handles endianess and
elfsize at runtime.

The patch also shuffles around the include files a bit.  Now there is
*one* include file holding all the elf structures
(xen/include/public/elfstructs.h) which is included by everyone who
needs them.

It's dead code with this patch only, putting the code into use happens
in followup patches.
