* src/qemu_conf.c: Fix leak of values upon OOM
* src/xend_internal.c: Fix missing check for OOM failure
* tests/qemuargv2xmltest.c, tests/qemuxml2argvtest.c: Free
  stateDir upon exit to avoid leak

* src/logging.c: Fix buffer offset in logging read

Fix all thread locking bugs reported by object-locking test
case.

NB, some of the driver locking is getting too coarse. Driver
mutexes really need to be turned into RW locks instead to
significantly increase concurrency.

* src/lxc_driver.c: Fix useof driver when unlocked in the methods
  lxcDomainGetInfo, lxcSetSchedulerParameters, and
  lxcGetSchedulerParameters
* src/opennebula/one_driver.c: Fix missing unlock in oneDomainUndefine.
  Fix use of driver when unlocked in oneDomainGetInfo,
  oneGetOSType, oneDomainShutdown
* src/qemu_driver.c: Fix use of driver when unlocked in
  qemudDomainSavem, qemuGetSchedulerType, qemuSetSchedulerParameters
  and qemuGetSchedulerParameters
* src/storage_driver.c: Re-work storagePoolCreate to avoid bogus
  lock checking warning. Re-work storageVolumeCreateXMLFrom to
  remove a potential NULL de-reference & avoid bogus lock check
  warnings
* src/test.c: Remove testDomainAssignDef since it break lock chekc
  warnings.
* tests/object-locking.ml: Add oneDriverLock, oneDriverUnlock
  and one_driver_t methods/types to allow lock checking on the
   OpenNebula drivers

* tests/testutilsqemu.c: add a machine types list for /usr/bin/kvm
  which doesn't have any aliases, while the guest has aliases

* tests/qemuxml2argvdata/qemuxml2argv-machine-aliases2.*,
  tests/qemuxml2argvtest.c: add a test using /usr/bin/kvm and make
  sure that 'pc' machine type doesn't get canonicalized using the
  aliases in the guest machine type list

The algorithm is quite simple:

  If the emulator matches a guest's domain:
    if domain has machine type info:
      check the domain's machine type info
    else
      check the guest's default machine type info
  else if the emulator matches the guest's default emulator:
     check the guest's default machine type info

The previous implementation was incorrectly falling back to the default
machine type info if the domain's machine type info didn't have an
alias.

* src/qemu_driver.c: simplify and fix qemudCanonicalizeMachine()

Currently we only probe the main qemu binary for machine types, but we
should also probe the kvm binary.

* src/qemu_conf.c: probe kvm binary machines in qemudCapsInitGuest()

Rather than just looking at the default domain info, look at all
domains

* src/qemu_conf.c: look at all domains in qemudGetOldMachines()

We need to look at all the domain infos in guest capabilities, not
just the defaults.

In order to allow that, split out a qemudGetOldMachinesFromInfo()
from qemudGetOldMachines(). We'll make more use of it in the next
patch.

* src/qemu_conf.c: split out qemudGetOldMachinesFromInfo() from
  qemudGetOldMachines()

* tests/testutilsqemu.c: make 'pc' an alias for qemu-system-x86_64

* tests/qemuxml2argvdata/qemuxml2argv-machine-aliases1.*,
  tests/qemuxml2argvtest.c: add a test which uses qemu-system-x86_64
  and make sure the machine type is canonicalized.

* test/testutilsqemu.c: split out code to testQemuAllocMachines()
  and make use of the ARRAY_CARDINALITY macro

This doesn't have any affect on the current tests because we don't have
any machine aliases in the current test data.

* src/qemu_conf.h, src/qemu_driver.c: expose qemudCanonicalizeMachine()
  for the tests

* tests/qemuxml2argvtest.c: canonicalize the machine type

* src/testutils.[ch]: make testDebug externally available

* src/testutilsqemu.c: if VIR_TEST_DEBUG is set, dump the qemu
  driver capabilities to stderr

* src/capabilities.c: fix machine type formatting in
  virCapabilitiesFormatXML()

* tests/qemuhelpdata/qemu-kvm-0.11.0-rc2: add data

* tests/qemuhelptest.c: add expected output

Things added include

  - x86_64 host
  - Migration features
  - NUMA topology
  - Security model
  - Canonical machine types
  - Domain machine types
  - An arm guest
  - More machine types for mips, mipsel, sparc and ppc
  - An x86_64 xenner guest

This file was generated on a Fedora 12 machine using latest libvirt
and qemu-kvm-0.11.0-rc2

* tests/capabilityschemadata/caps-qemu-kvm.xml: add more features
  to test

* docs/schemas/capabilities.rng: add arm and sort arches

* docs/schemas/capabilities.rng: allow multiple machines per domain
  just like they are allowed for guests

* docs/schemas/capabilities.rng: include esx and tcp uri_transport

After the mentioned patch was applied, I noticed that
shutting down a kvm guest from inside (i.e. poweroff) caused
the guest to shutdown, but not removed from the list of
active guests.  DanB pointed out that the problem is that
the virEventAddHandle() call in the qemu driver was asking
to watch for 0 events, not HANGUP | ERROR as it should.  Add
these events so that shutdown works again.

* src/qemu_driver.c (qemudDomainRestore): Use the new ...TypeToString
function here, too.

* src/qemu_driver.c: avoid a leak of file descriptor when exec'ing qemu

lzop was removed due to some confusion over whether it provided functional
advantages distinct from xz. This has been addressed in the mailing list post
archived at http://permalink.gmane.org/gmane.comp.emulators.libvirt/16487, and
support for lzop is re-added here.

* libvirt.spec.in: add dependancy on lzop
* src/qemu.conf: update documentation of save_image_format
* src/qemu_driver.c: re-add lzop compression option

* src/qemu_driver.c: drop lzma and lzop images compression options
  as they are deprecated by xz
* libvirt.spec.in: add requires for xz/bzip2/gzip as they are needed
  to implement the compression options

* configure.in: phyp driver uses libssh2_session_block_directions()
  which is only available in libssh2 >= 1.0, so check for this symbol
  too when configuring

* src/qemu_driver.c (QEMUD_SAVE_FORMAT_LAST): Define.
(qemudSaveCompressionTypeFromString): Declare.
(qemudSaveCompressionTypeToString): Declare.
(qemudDomainSave): Use those functions rather than open-coding them.
Use "cat >> '%s' ..." in place of equivalent
"dd of='%s' oflag=append conv=notrunc ...".

* src/qemu_driver.c (enum qemud_save_formats) [QEMUD_SAVE_FORMAT_XZ]:
New member.

* src/openvz_conf.c (openvzReadNetworkConf): Replace open-coded
while loop with equivalent use of strchrnul.
* bootstrap (modules): Add strchrnul.
