Fix multiple veth problem.
NETIF setting was overwritten after first CT because any CT could not be
found by name.
* src/openvz/openvz_conf.c src/openvz/openvz_conf.h: add the
openvzGetVEID lookup function
* src/openvz/openvz_driver.c: use it in openvzDomainSetNetwork()
Set up the types for the domainMemoryStats function and insert it into the
virDriver structure definition. Because of static initializers, update
every driver and set the new field to NULL.
* include/libvirt/libvirt.h.in: new API
* src/driver.h src/*/*_driver.c src/vbox/vbox_tmpl.c: add the new
entry to the driver structure
* python/generator.py: fix compiler errors, the actual python binding is
implemented later
* src/driver.h: add an extra entry point in the structure
* src/esx/esx_driver.c src/lxc/lxc_driver.c src/opennebula/one_driver.c

src/vbox/vbox_tmpl.c src/xen/xen_driver.c: add NULL entry points for
all drivers
Replace free(virBufferContentAndReset()) with virBufferFreeAndReset().
Update documentation and replace all remaining calls to free() with
calls to VIR_FREE(). Also add missing calls to virBufferFreeAndReset()
and virReportOOMError() in OOM error cases.
There is currently no way to determine the libvirt version of a remote
libvirtd we are connected to. This is a useful piece of data to enable
feature detection.
Introduce a number of new APIs to expose some boolean properties
of objects, which cannot otherwise reliably determined, nor are
aspects of the XML configuration.
* virDomainIsActive: Checking virDomainGetID is not reliable
since it is not possible to distinguish between error condition
and inactive domain for ID of -1.
* virDomainIsPersistent: Check whether a persistent config exists
for the domain
* virNetworkIsActive: Check whether the network is active
* virNetworkIsPersistent: Check whether a persistent config exists
for the network
* virStoragePoolIsActive: Check whether the storage pool is active
* virStoragePoolIsPersistent: Check whether a persistent config exists
for the storage pool
* virInterfaceIsActive: Check whether the host interface is active
* virConnectIsSecure: whether the communication channel to the
hypervisor is secure
* virConnectIsEncrypted: whether any network based commnunication
channels are encrypted
NB, a channel can be secure, even if not encrypted, eg if it does
not involve the network, like a UNIX socket, or pipe.
* include/libvirt/libvirt.h.in: Define public API
* src/driver.h: Define internal driver API
* src/libvirt.c: Implement public API entry point
* src/libvirt_public.syms: Export API symbols

Rename virDomainIsActive to virDomainObjIsActive, and
virInterfaceIsActive to virInterfaceObjIsActive and finally
virNetworkIsActive to virNetworkObjIsActive.

The virDomainObjPtr object stores state about a running domain.
This object is shared across all drivers so it is not appropriate
to include driver specific state here. This patch adds the ability
to request a blob of private data per domain object instance. The
driver must provide a allocator & deallocator for this purpose
THis patch abuses the virCapabilitiesPtr structure for storing the
allocator/deallocator callbacks, since it is already being abused
for other internal things relating to parsing. This should be moved
out into a separate object at some point.
* src/conf/capabilities.h: Add privateDataAllocFunc and
privateDataFreeFunc fields
* src/conf/domain_conf.c: Invoke the driver allocators / deallocators
when creating/freeing virDomainObjPtr instances.
* src/conf/domain_conf.h: Pass virCapsPtr into virDomainAssignDef
to allow access to the driver specific allocator function
* src/lxc/lxc_driver.c, src/opennebula/one_driver.c,
src/openvz/openvz_driver.c, src/qemu/qemu_driver.c,
src/test/test_driver.c, src/uml/uml_driver.c: Update for
change in virDomainAssignDef contract
The current virDomainObjListPtr object stores domain objects in
an array. This means that to find a particular objects requires
O(n) time, and more critically acquiring O(n) mutex locks.
The new impl replaces the array with a virHashTable, keyed off
UUID. Finding a object based on UUID is now O(1) time, and only
requires a single mutex lock. Finding by name/id is unchanged
in complexity.
In changing this, all code which iterates over the array had
to be updated to use a hash table iterator function callback.
Several of the functions which were identically duplicating
across all drivers were pulled into domain_conf.c
* src/conf/domain_conf.h, src/conf/domain_conf.c: Change
virDomainObjListPtr to use virHashTable. Add a initializer
method virDomainObjListInit, and rename virDomainObjListFree
to virDomainObjListDeinit, since its not actually freeing
the container, only its contents. Also add some convenient
methods virDomainObjListGetInactiveNames,
virDomainObjListGetActiveIDs and virDomainObjListNumOfDomains
which can be used to implement the correspondingly named
public API entry points in drivers
* src/libvirt_private.syms: Export new methods from domain_conf.h

src/openvz/openvz_conf.c, src/openvz/openvz_driver.c,
src/qemu/qemu_driver.c, src/test/test_driver.c,
src/uml/uml_driver.c, src/vbox/vbox_tmpl.c: Update all code
to deal with hash tables instead of arrays for domains
Implementation of tunnelled migration, using a Unix Domain Socket
on the qemu backend. Note that this requires very new versions of
qemu (0.10.7 at least) in order to get the appropriate bugfixes.
