This patch improves the error checking in the LOCAL_PEERCRED version
of virNetSocketGetUNIXIdentity, used by FreeBSD and Mac OSX.

1. The error return paths now correctly unlock the socket. This is
implemented in exactly the same way as the SO_PEERCRED version,
using "goto cleanup"

2. cr.cr_ngroups is initialised to -1, and cr.cr_ngroups is checked
for negative and overlarge values.

This means that if the getsockopt() call returns success but doesn't
actually update the xucred structure, this is now caught. This
happened previously when getsockopt was called with SOL_SOCKET
instead of SOL_LOCAL, prior to commit 5a468b38, and resulted in
random uids being accepted.

prevent aclocal from preferring .m4 files under m4/ over the version
provided by gnulib, by using only one directory.

I have noticed this after './configure --help' gave me two different
versions of "--enable-threads".  This was caused by aclocal that
preferred the version of lock.m4 provided by autopoint instead of
using the newer version distributed with gnulib.

Having two different directories made sense back when we checked
gnulib files into libvirt.git, but that was ages ago.

The recent patch series proposing the addition of PPC little endian
arch support to Linux defines new arch names 'ppcle' and 'ppc64le':

https://lists.ozlabs.org/pipermail/linuxppc-dev/2013-August/109908.html

This just makes libvirt know about these arch names, so it doesn't
immediately trip up if it seems these new names from uname.

This should resolve:

  https://bugzilla.redhat.com/show_bug.cgi?id=924672

For BZ 924672 the problem stems from the fact that thin pool logical
volume devices show up in /sbin/lvs output just like normal logical
volumes do. Libvirt incorrectly assumes they are just normal logical
volumes and that they will have a corresponding /dev/vgname/lvname
device that has been created by udev and tries to use this device.

To illustrate here is an example of the /dev/vgname/ directory and
the lvs output for a normal lv, thin lv, and thin pool:

    LV     VG       Attr      LSize  Pool Origin Data%  Move Log Copy%  Convert
    lv     vgguests -wi-a----  1.00g
    pool   vgguests twi-a-tz- 11.00g               0.00
    thinlv vgguests Vwi-a-tz-  1.00g pool          0.00
total 0
lrwxrwxrwx. 1 root root 7 Oct  8 19:35 lv -> ../dm-7
lrwxrwxrwx. 1 root root 7 Oct  8 19:37 thinlv -> ../dm-6

This patch modifies virStorageBackendLogicalMakeVol() to ignore thin pool
devices.

Some ancient gcc fails to see the variables are initialized in a
separate function and a false positive is produced:

Avoid a line exceeding 80 characters and change argument alignment in
two error messages.

These return boolean results.

Use virCPUx86DataIterator and virCPUx86DataIteratorInit.

This patch adds cpuDataFormat and cpuDataParse APIs to be used in unit
tests for testing APIs that deal with virCPUData. In the x86 world, this
means we can now store/load arbitrary CPUID data in the test suite to
check correctness of CPU related APIs that could not be tested before.

VirtualBox has 'saved' state for VMs saved by the hypervisor.
However, the state is treated as VIR_DOMAIN_NOSTATE by the vbox
driver, resulting that virsh shows 'no state' for saved VMs.
