d010b68962 make NUMA-initialization code more portable and more robust
qemudCapsInitNUMA and umlCapsInitNUMA were identical, so this change
factors them into a new function, virCapsInitNUMA, and puts it in
nodeinfo.c.

In addition to factoring out the duplicates, this change also
adjusts that function definition (along with its macros) so
that it works with Fedora 9's numactl version 1, and makes it
so the code will work even if someone builds the kernel with
CONFIG_NR_CPUS > 4096.

Finally, also perform this NUMA initialization for the lxc
and openvz drivers.

* src/nodeinfo.c: Include <stdint.h>, <numa.h> and "memory.h".
(virCapsInitNUMA): Rename from qemudCapsInitNUMA and umlCapsInitNUMA.
(NUMA_MAX_N_CPUS): Define depending on NUMA API version.
(n_bits, MASK_CPU_ISSET): Define, adjust, use uint64 rather than long.
* src/nodeinfo.h: Include "capabilities.h".
(virCapsInitNUMA): Declare it.
* examples/domain-events/events-c/Makefile.am:
* src/Makefile.am: Add $(NUMACTL_CFLAGS) and $(NUMACTL_LIBS) to various
compile/link-related variables.
* src/qemu_conf.c: Include "nodeinfo.h".
(qemudCapsInitNUMA): Remove duplicate code.  Adjust caller.
* src/uml_conf.c (umlCapsInitNUMA): Likewise.
Include "nodeinfo.h".
* src/lxc_conf.c: Include "nodeinfo.h".
(lxcCapsInit): Perform NUMA initialization here, too.
* src/openvz_conf.c (openvzCapsInit): And here.
Include "nodeinfo.h".
* src/libvirt_sym.version.in: Add virCapsInitNUMA so that libvirtd
can link to this function.

7e6a06aeae fix numa-related (and kernel-dependent) test failures
This change is required on some kernels due to the way a change in
the kernel's CONFIG_NR_CPUS propagates through the numa library.
* src/qemu_conf.c (qemudCapsInitNUMA): Pass numa_all_cpus_ptr->size/8
as the buffer-length-in-bytes in the call to numa_node_to_cpus, since
that's what is required on second and subseqent calls.
* src/uml_conf.c (umlCapsInitNUMA): Likewise.
