56ecebf22d Re-factor qemu version parsing
This patch is purely re-factoring without any functional changes
to make way for the next patch.

The main thing achieved by the refactoring is that we now have
easier access to the parenthesised string that KVM folks seem
to delight in changing.

a331653dad Add pidfile argument to __virExec
virExec will write out the pid of the daemonized process only. Use this
in the QEMU driver, rather than QEMU's pidfile, so we can catch errors we
might miss if the emulator bails early.

9fa79000ec qemu -drive takes format= not fmt=
Seems like a simple typo - it has been "format=" since the flag
was introduced, but we added it as "fmt=".

b4f62abbf1 kvm/virtio: Set IFF_VNET_HDR when setting up tap fds
IFF_VNET_HDR is a tun/tap flag that allows you to send and receive
large (i.e. GSO) packets and packets with partial checksums. Setting
the flag means that every packet is proceeded by the same header which
virtio uses to communicate GSO/csum metadata.

By enabling this flag on the tap fds we create, we greatly increase
the achievable throughput with virtio_net.

However, we need to be careful to only set the flag when a) QEMU has
support for this ABI and b) the value of the flag is queryable using
the TUNGETIFF ioctl.

It's nearly five months since kvm-74 - the first KVM release with this
feature - was released. Up until now, we've not added libvirt support
because there is no clean way to detect support for this in QEMU at
runtime. A brief attempt to add a "info capabilities" monitor command
to QEMU floundered. Perfect is the enemy of good enough. Probing the
KVM version will suffice for now.

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.
