f3439c7eae openvzGetVEID: don't leak (memory + file descriptor)
* src/openvz/openvz_conf.c (openvzGetVEID): Always call fclose.
Diagnose parse failure also when vzlist output is empty.
If somehow we read a -1, diagnose that (albeit as a parse failure).

ead3410f30 fix multiple veth problem for OpenVZ
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()

1b9d074493 Add virBufferFreeAndReset() and replace free()
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.

cabc2cc98f Implmentation of new APIs to checking state/persistence of objects
This implements the virConnectIsSecure, virConnectIsEncrypted,
virDomainIsPersistent, virDomainIsActive, virNetworkIsActive,
virNetworkIsPersistent, virStoragePoolIsActive,
virStoragePoolIsPersistent, virInterfaceIsActive APIs in
(nearly) all drivers. Exceptions are:

 phyp: missing domainIsActive/Persistent
 esx: missing domainIsPersistent
 opennebula: missing domainIsActive/Persistent

* src/remote/remote_protocol.x: Define remote wire ABI for newly
  added APIs.
* daemon/remote_dispatch*.h: Re-generated from remote_protocol.x
* src/esx/esx_driver.c, src/lxc/lxc_driver.c, src/network/bridge_driver.c,

a340f9131a Add reference counting on virDomainObjPtr objects
Add reference counting on the virDomainObjPtr objects. With the
forthcoming asynchronous QEMU monitor, it will be neccessary to
release the lock on virDomainObjPtr while waiting for a monitor
command response. It is neccessary to ensure one thread can't
delete a virDomainObjPtr while another is waiting. By introducing
reference counting threads can make sure objects they are using
are not accidentally deleted while unlocked.

* src/conf/domain_conf.h, src/conf/domain_conf.c: Add
  virDomainObjRef/Unref APIs, remove virDomainObjFree
* src/openvz/openvz_conf.c: replace call to virDomainObjFree
  with virDomainObjUnref

a3adcce795 Convert virDomainObjListPtr to use a hash of domain objects
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/lxc/lxc_driver.c, src/opennebula/one_driver.c,
  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

03d777f345 Introduce virStrncpy.
Add the virStrncpy function, which takes a dst string, source string,
the number of bytes to copy and the number of bytes available in the
dest string.  If the source string is too large to fit into the
destination string, including the \0 byte, then no data is copied and
the function returns NULL.  Otherwise, this function copies n bytes
from source into dst, including the \0, and returns a pointer to the
dst string.  This function is intended to replace all unsafe uses
of strncpy in the code base, since strncpy does *not* guarantee that
the buffer terminates with a \0.
