[PATCH v1] Add build-id to XENVER hypercall.

[Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>]

Hey,

Attached are the four patches that will add XENVER_build_id and
add the proper bits in libxl/libxc.

However they also change the behavior of the existing hypercall
for XENVER_[compile_info|changeset|commandline] and make them
dom0 accessible. This is if XSM is built in or not (though with
XSM one can expose it to a guest if desired).

Please take a look and provide your feedback at your leisure.

Note:
 * Hadn't tried compiling it on ARM cross compiler lately. In
   the past I had to #ifdef CONFIG_ARM as the ARM code did not
   use any ELF code so none of the ELF parts made any sense.
 * The EFI build works kindof. It is missing an build_id.o stanza.
