These macros were hiding that the ops are not zero-initialized by the
toolstack. This is needlessly opaque for something so simple, so this patch
removes them and replaces them with explicit zero-initialising versions.
The patch also removes PHYSDEV_OP from there, as that seems to be an old
dead macro.

Currently it's hard to get CPU's microcode revision from Xen after late
loading without looking into Xen logs, which is not always convenient.
Add a new platform op in order to get the required data from Xen and
provide a wrapper for libxenctrl.

The first thing XEN_SYSCTL_physinfo does is zero op->u.physinfo.
Do not copy-in. It's pointless, and most callers don't initialise their
xc_physinfo_t buffer to begin with. Remove the redundant zeroing from the
remaining callers.

Today tools/libxc needs to be built after tools/libs as libxenctrl is
depending on some libraries in tools/libs. This in turn blocks moving
other libraries depending on libxenctrl below tools/libs.
So carve out libxenctrl from tools/libxc and move it into
tools/libs/ctrl.
