34d63dd750 Include GNULIB mkdtemp module
The mkdtemp function is missing on mingw platforms. It is
used in various Linux specific places in libvirt, but
recently became used in fdstreamtest.c which is cross
platform. Thus the GNULIB mkdtemp module should be used
to provide mkdtemp.

3e5752747c Set PKG_CONFIG_LIBDIR in autobuild.sh
If PKG_CONFIG_LIBDIR is not set when doing mingw32/64 builds,
then pkg-config may silently fallback to native versions of
libraries, with predictably bad results. Setting PKG_CONFIG_LIBDIR
forces it to only consider the mingw32/64 libraries.

6459af6a43 qemu: report useful error failling to destroy domain gracefully
Resolves:https://bugzilla.redhat.com/show_bug.cgi?id=927620

 #kill -STOP `pidof qemu-kvm`
 #virsh destroy $guest --graceful
 error: Failed to destroy domain testVM
 error: An error occurred, but the cause is unknown

With --graceful, SIGTERM always is emitted to kill driver
process, but it won't success till burning out waiting time
in case of process being stopped.
But domain destroy without --graceful can work, SIGKILL will
be emitted to the stopped process after 10 secs which always
kills a process even one that is currently stopped.
So report an error after burning out waiting time in this case.

c2cf5f1c2a Fix failure to detect missing cgroup partitions
Change bbe97ae968 caused the
QEMU driver to ignore ENOENT errors from cgroups, in order
to cope with missing /proc/cgroups. This is not good though
because many other things can cause ENOENT and should not
be ignored. The callers expect to see ENXIO when cgroups
are not present, so adjust the code to report that errno
when /proc/cgroups is missing

9049d6a8c7 qemu: Change values of disk discard
QEMU might support more values for "-drive discard", so using Bi-state
values (on/off) for it doesn't make sense.

"on" maps to "unmap", "off" maps to "ignore":

<...>
@var{discard} is one of "ignore" (or "off") or "unmap" (or "on") and
controls whether @dfn{discard} (also known as @dfn{trim} or @dfn{unmap})
requests are ignored or passed to the filesystem.  Some machine types
may not support discard requests.

aeda1ff12d qemu: Refactor the helpers to track shared scsi host device
This changes the helpers qemu{Add,Remove}SharedDisk into
qemu{Add,Remove}SharedDevice, as most of the code in the helpers
can be reused for scsi host device.

To track the shared scsi host device, first it finds out the
device path (e.g. /dev/s[dr]*) which is mapped to the sg device,
and use device ID of the found device path (/dev/s[dr]*) as the
hash key. This is because of the device ID is not unique between
between /dev/s[dr]* and /dev/sg*, e.g.

% sg_map
/dev/sg0  /dev/sda
/dev/sg1  /dev/sr0

% ls -l /dev/sda
brw-rw----. 1 root disk 8, 0 May  2 19:26 /dev/sda

%ls -l /dev/sg0
crw-rw----. 1 root disk 21, 0 May  2 19:26 /dev/sg0

539d0e19fd qemu: Rename qemu_driver->sharedDisks to qemu_driver->sharedDevices
"Shared disk" is not only the thing we should care about after "scsi

one domain, and as "scsi hostdev" for another domain at the same time.
That's why this patch renames qemu_driver->sharedDisks. Related functions
and structs are also renamed.

ba5f3c7c8e Move VirtualBox driver into libvirtd
Change the build process & driver initialization so that the
VirtualBox driver is built into libvirtd, instead of libvirt.so
This change avoids the VirtualBox GPLv2-only license causing
compatibility problems with libvirt.so which is under the
GPLv2-or-later license.

NB this change prevents use of the VirtualBox driver on the
Windows platform, until such time as libvirtd can be made
to work there.

d7d7581b03 Fix LXC startup when /var/run is an absolute symlink
During startup, the LXC driver uses paths such as

  /.oldroot/var/run/libvirt/lxc/...

to access directories from the previous root filesystem
after doing a pivot_root(). Unfortunately if /var/run
is an absolute symlink to /run, instead of a relative
symlink to ../run, these paths break.

At least one Linux distro is known to use an absolute
symlink for /var/run, so workaround this, by resolving
all symlinks before doing the pivot_root().

a6a04ea47a nwfilter: check for inverted ctdir
Linux netfilter at some point (Linux 2.6.39) inverted the meaning of the
'--ctdir reply' and newer netfilter implementations now expect
'--ctdir original' instead and vice-versa.
We check for the kernel version and assume that all Linux kernels with version
2.6.39 have the newer inverted logic.

Any distro backporting the Linux kernel patch that inverts the --ctdir logic
(Linux commit 96120d86f) must also backport this patch for Linux and
adapt the kernel version being tested for.

a2c37618d3 Adjust improperly formatted <sysinfo> uuid
If the <sysinfo> system table 'uuid' field is improperly formatted,
then qemu will fail to start the guest with the error:

virsh start dom
error: Failed to start domain dom
error: internal error process exited while connecting to monitor: Invalid SMBIOS UUID string

This was because the parsing rules were lax with respect to allowing extraneous
spaces and dashes in the provided UUID.  As long as there were 32 hexavalues
that matched the UUID for the domain the string was accepted. However startup
failed because the string format wasn't correct. This patch will adjust the
string format so that when it's presented to the driver it's in the expected
format.

Added a test for uuid comparison within sysinfo.
