[Xen-devel][PATCH] libxc bitmap utils and vcpu-affinity

[Dulloor <dulloor@xxxxxxxxx>]

This patch adds :

* A byte-based cpumask type(xenctl_cpumask) for setting vcpu-affinity
as well as numa-node-affinity, etc in libxc.

* Add common bitmap utils to libxc, which can be used both for
xenctl_cpumask (and with small changes for xenctl_cpumap, if desired),
so that we can do common operations on cpumask easily.

As opposed to xenctl_cpumap, xenctl_cpumask is a static structure
(just 4 bytes larger for 128 cpus), but keeps the interface/code
cleaner. The domctl_interface version keeps the size of xenctl_cpumask
consistent between xen and xen-tools.
