Invoking virDomainSetMemory() on lxc driver results in libvirtd
segfault when cgroups has not been configured on the host.
Ensure driver->cgroup is non-null before invoking
virCgroupForDomain(). To prevent similar segfaults in the future,
ensure driver parameter to virCgroupForDomain() is non-null before
dereferencing.
"virsh dominfo <vm>" crashes if there's no primary security driver set
since we only intialize the secmodel.model and secmodel.doi if we have
one. Attached patch checks for securityPrimaryDriver instead of
securityDriver since the later is always set in qemudSecurityInit().

Attempt to turn on vhost-net mode for devices of type NETWORK, BRIDGE,
and DIRECT (macvtap).
* src/qemu/qemu_conf.h: add vhostfd to qemuBuildHostNetStr prototype
add qemudOpenVhostNet prototype new flag to set when :,vhost=" found in
qemu help
* src/qemu/qemu_conf.c: * set QEMUD_CMD_FLAG_VNET_HOST is ",vhost=" found
in qemu help
- qemudOpenVhostNet - opens /dev/vhost-net to pass to qemu if everything
is in place to use it.
- qemuBuildHostNetStr - add vhostfd to commandline if it's not empty
(higher levels decide whether or not to fill it in)
- qemudBuildCommandLine - if /dev/vhost-net is successfully opened, add
its fd to tapfds array so it isn't closed on qemu exec, and populate
vhostfd_name to be passed in to commandline builder.
* src/qemu/qemu_driver.c: add filler 0 for new arg to qemuBuildHostNetStr,
along with a note that this must be implemented in order for hot-plug of
vhost-net virtio devices to work properly (once qemu "netdev_add" monitor
command is implemented).
POSIX states that creation of a mutex with default attributes
is unspecified whether the mutex is recursive or non-recursive.
We specifically want non-recursive (deadlock is desirable in
flushing out coding bugs that used our mutex incorrectly).
* src/util/threads-pthread.c (virMutexInit): Specifically request
non-recursive mutex, rather than relying on unspecified default.

* daemon/libvirtd.init.in: daemon/libvirtd.init.in were not mentionned
in the usage message and if a missing or wrong argument is given it
should return 2, not 1
According to:
http://libvirt.org/html/libvirt-libvirt.html#virNetworkLookupByUUID
virNetworkLookupByUUID() expects a virConnectPtr as its first argument,
thus making it a method of the virConnect Python class.
Currently it's a method of libvirt.virNetwork.

Currently no command can be sent to a qemu process while another job is
active. This patch adds support for signaling long-running jobs (such as
migration) so that other threads may request predefined operations to be
done during such jobs. Two signals are defined so far:
- QEMU_JOB_SIGNAL_CANCEL
- QEMU_JOB_SIGNAL_SUSPEND
The first one is used by qemuDomainAbortJob.
The second one is used by qemudDomainSuspend for suspending a domain
during migration, which allows for changing live migration into offline
migration. However, there is a small issue in the way qemudDomainSuspend
is currently implemented for migrating domains. The API calls returns
immediately after signaling migration job which means it is asynchronous
in this specific case.

* autogen.sh (bootstrap_hash): New function.
Running bootstrap may update the gnulib SHA1, yet we were computing
t=$(git submodule status ...) *prior* to running bootstrap, and
then recording that sometimes-stale value in the stamp file upon
a successful bootstrap run. That would require two (lengthy!)
bootstrap runs to update the stamp file.
* src/qemu/qemu_driver.c (qemudDomainAttachSCSIDisk): The ".controller"
member is an index, and *may* be 0. As such, the commit that we're
reverting broke SCSI disk hot-plug on controller 0.
Reported by Wolfgang Mauerer.
We need to call PrepareHostdevs to determine the USB device path before
any security calls. PrepareHostUSBDevices was also incorrectly skipping
all USB devices.
* src/qemu/qemu_conf.c: add the ",readonly=on" for read-only disks
and also parse it back in qemuParseCommandLineDisk()
