[Xen-devel] [PATCH v3 1/3] libxl/cpumap: Add xc_cpumap_[setcpu, clearcpu, testcpu] to complement xc_cpumap_alloc.

[Konrad Rzeszutek Wilk <konrad.wilk@xxxxxxxxxx>]

We export the xc_cpumap_alloc but not the bit operations.
One could include 'xc_bitops.h' but that is naughty - so instead
we just export the proper functions to do it on the xc_cpumap_t
typedef.
