As part of this make the usual change to xen_ulong_t in place of unsigned long.
This change has no impact on x86.
The Linux definition of struct multicall_entry.result differs from the Xen
definition, I think for good reasons, and used a long rather than an unsigned
long. Therefore introduce a xen_long_t, which is a long on x86 architectures
and a signed 64-bit integer on ARM.
Use uint32_t nr_calls on x86 for consistency with the ARM definition.
Build tested on amd64 and i386 builds. Runtime tested on ARM.
