tools/libs/ctrl: rename and export do_memory_op as xc_memory_op
Make the do_memory_op function accessible to tools linking with libxc.
Similar functions are already available for both domctl and sysctl. As part
of this patch we also change the input 'cmd' to be unsigned int to
accurately
reflect what the hypervisor expects.
