[v4,0/6] lib{xc,xl}: support for guest MSR features

Message

Hello,

The following series adds support for handling guest MSR features as
defined in arch-x86/cpufeatureset.h.

The end result is the user being able to use such features with the
xl.cfg(5) cpuid option.  This also involves adding support to all the
underlying layers, so both libxl and libxc also get new functionality in
order to properly parse those.

Thanks, Roger.
