[libvirt] [PATCHv2 1/9] virNodeGetCPUMapFlags: Define public API.



Adding a new API to obtain information about the
host node's present, online and offline CPUs.

int virNodeGetCPUMapFlags(virConnectPtr conn,
                          unsigned char **cpumap,
    			  unsigned int *online,
                          unsigned int flags);

The function will return the number of CPUs present on the host
or -1 on failure;
If cpumap is non-NULL virNodeGetCPUMapFlags will allocate an array
containing a bit map representation of the online CPUs. It's
the callers responsibility to deallocate cpumap using free().
If online is non-NULL, the variable pointed to will contain
the number of online host node CPUs.
The variable flags has been added to support future extensions
and must be set to 0.

Note: the name virNodeGetCPUMapFlags has been chosen to avoid
confusion with the nodeinfo function nodeGetCPUmap.
