Introduce a 'virArch' enum for CPU architectures. Include
data type providing wordsize and endianness, and APIs to
query this info and convert to/from enum and string form.

This adds support for host device passthrough with the
LXC driver. Since there is only a single kernel image,
it doesn't make sense to pass through PCI devices, but
USB devices are fine. For the latter we merely need to
make the /dev/bus/usb/NNN/MMM character device exist
in the container's /dev

The virtlockd daemon scripts were lousy, when compared to their
counterparts in daemon/Makefile.am. In particular, when init
scripts were selected, this resulted in 'make distcheck' failing
due to failure to clean up src/virtlockd.init.
* src/Makefile.am (install-systemd): Fix dependencies. Use MKDIR_P.
(uninstall-systemd): Remove empty directory. Use fewer processes.
(install-init, install-sysconfig): Use MKDIR_P.
(uninstall-init): Remove correct file, and also empty directory.
(uninstall-sysconfig): Remove empty directory.
(DISTCLEANFILES): Clean up trivially built sources.
The default lockd driver behavour is to acquire leases
directly on the disk files. This introduces an alternative
mode, where leases are acquire indirectly on a file that
is based on a SHA256 hash of the disk filename.

This adds a 'lockd' lock driver which is just a client which
talks to the lockd daemon to perform all locking. This will
be the default lock driver for any hypervisor which needs one.

This enhancement virtlockd so that it can receive a pre-opened
UNIX domain socket from systemd at launch time, and adds the
systemd service/socket unit files
* daemon/libvirtd.service.in: Require virtlockd to be running
* libvirt.spec.in: Add virtlockd systemd files
* src/Makefile.am: Install systemd files
* src/locking/lock_daemon.c: Support socket activation
* src/locking/virtlockd.service.in, src/locking/virtlockd.socket.in:
systemd unit files
* src/rpc/virnetserverservice.c, src/rpc/virnetserverservice.h:
Add virNetServerServiceNewFD() method
* src/rpc/virnetsocket.c, src/rpc/virnetsocket.h: Add virNetSocketNewListenFD

The virtlockd daemon will be responsible for managing locks
on virtual machines. Communication will be via the standard

The virtlockd daemon will maintain locks on behalf of libvirtd.
There are two reasons for it to be separate
- Avoid risk of other libvirtd threads accidentally
releasing fcntl() locks by opening + closing a file
that is locked
- Ensure locks can be preserved across libvirtd restarts.
virtlockd will need to be able to re-exec itself while
maintaining locks. This is simpler to achieve if its
sole job is maintaining locks

Parallels Cloud Server uses virtual networks model for network
configuration. It uses own tools for virtual network management.
So add network driver, which will be responsible for listing
virtual networks and performing different operations on them
(in consequent patched).
This patch only allows listing virtual network names, without
any parameters like DHCP server settings.

Implement the domainManagedSave, domainHasManagedSaveImage, and
domainManagedSaveRemove functions in the libvirt legacy xen driver.
domainHasManagedSaveImage check the managedsave image from filesystem
everytime. This is different from qemu and libxl driver. In qemu or
libxl driver, there is a hasManagesSave flag in virDomainObjPtr which
is not used in xen legacy driver. This flag could not add into xen
driver ptr either, because the driver ptr will be released at the end of
every libvirt api call. Meanwhile, AFAIK, xen store all the flags in
xen not in libvirt xen driver. There is no need to add this flag in xen.

Currently to deal with auto-shutdown libvirtd must periodically
poll all stateful drivers. Thus sucks because it requires
acquiring both the driver lock and locks on every single virtual
machine. Instead pass in a "inhibit" callback to virStateInitialize
which drivers can invoke whenever they want to inhibit shutdown
due to existance of active VMs.

The patch adds the backend driver to support iSCSI format storage pools
and volumes for ESX host. The mapping of ESX iSCSI specifics to Libvirt
is as follows:
1. ESX static iSCSI target <------> Libvirt Storage Pools
2. ESX iSCSI LUNs <------> Libvirt Storage Volumes.
The above understanding is based on http://libvirt.org/storage.html.
The operation supported on iSCSI pools includes:
1. List storage pools & volumes.
2. Get XML descriptor operaion on pools & volumes.
3. Lookup operation on pools & volumes by name, UUID and path (if applicable).
iSCSI pools does not support operations such as: Create / remove pools
and volumes.
This introduces a few new APIs for dealing with strings.
One to split a char * into a char **, another to join a
char ** into a char *, and finally one to free a char **
There is a simple test suite to validate the edge cases
too. No more need to use the horrible strtok_r() API,
or hand-written code for splitting strings.
