xen: arm: include public/xen.h in foreign interface checking
mkheader.py doesn't cope with
struct foo { };
so add a newline.
Define unsigned long and long to a non-existent type on ARM so as to catch
their use.
Teach mkheader.py to cope with structs which are ifdef'd. This cannot cope
with #defines between the #ifdef and the struct definitions, so move
MAX_GUEST_CMDLINE to be next to its only usage.
