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.

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.

 #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.

Just like previous patches, this changes qemuCheckSharedDisk
into qemuCheckSharedDevice, which takes a virDomainDeviceDefPtr
argument instead.

Running make check in a VPATH configured build directory fails
in fchosttest as the test data files are searched for relative to
the current working directory.

Change bbe97ae9 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

This reverts commit 940c6f10.

libxl expects the event handler to free the event passed to it.  From
libxl_event.h:

   event becomes owned by the application and must be freed, either
   by event_occurs or later

Xen 4.3 fixes a mistake in the libxl event handler signature where the
event owned by the application was defined as const.  Detect this and
define the libvirt libxl event handler signature appropriately.

We don't parse it anyway.

Make target path mandatory for pool types that require target,
since we refuse to parse a target without a path.

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.
</...>

The following XML configuration can be used to request all domain's
memory pages to be kept locked in host's memory (i.e., domain's memory
pages will not be swapped out):

      <memoryBacking>
        <locked/>
      </memoryBacking>

Commit ba5f3c7c moved vbox driver into libvirtd but forgot to adapt
daemon's Makefile.am.

Commit 632f78ca introduced a regression which causes schedinfo being
unable to set some parameters.  When migrating to priv->cgroup there
was missing variable left out and due to passed NULL to underlying
function, the setting failed.

Just like what previous patches do, it refactors qemuSetUnprivSGIO
to take the virDomainDeviceDefPtr as argument instead.

unpriv_sgio setting is tight with the shared device helpers, let's
put them together in qemu_conf.c

"sgio" is only valid for scsi host device.

SCSI host device will also support "sgio", and perhaps we could
use "sgio" in other places too in future, renaming the enum to
reuse.

This adds the shared device entry when starting domain (more
exactly, when preparing host devices), and remove the entry
when destroying domain (when reattaching host devices).

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

E.g.

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

What the helper gets for /dev/sg0 is /dev/sda, it will be used by
later patch.

"Shared disk" is not only the thing we should care about after "scsi
hostdev" is introduced. A same scsi device can be used as "disk" for
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.

Unlike disk device, the scsi-generic always writethrough the data,
so no need to introduce a "cache" tag, and set "cache=off".

use is_selinux_enabled() to check if the machine actually

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.

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().

The reason for it's not exposed for such long time is that the
enums for VirtioEventIdx and CopyOnReadType have same enum values
and Correspondingstrings. This fixes the bug and adds test.
