* 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.
[QEMUD_SAVE_FORMAT_LZMA]: Mark as deprecated.
Use an explicit value for each member.
(qemudDomainSave, qemudDomainRestore): Handle the new member.
* src/qemu.conf: Mention xz, too.

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

* src/xend_internal.c: in xenDaemonLookupByID() if virGetDomain fails
  free up the name

* libvirt.spec.in: the new multipath module requires device-mapper
  and device-mapper-devel for build

* configure.in src/Makefile.am src/storage_backend.[ch]
  src/storage_conf.[ch] src/storage_backend_mpath.[ch] po/POTFILES.in:
  add a new module for storage multipath, it requires device-mapper

* src/xend_internal.c: free name in xenDaemonLookupByID() if
  virGetDomain() fails

* src/libvirt_private.syms: Add a missing comment for
  storage_encryption_conf.h entries

* src/storage_encryption_conf.c: small typo fix in top comment

* src/xm_internal.c (xenXMDomainConfigParse): After t=strchr...
don't test *t; it's known.  This was *not* detected by clang,
but I spotted it since once instance was in the vicinity of the
dead increment of "data".

* src/xm_internal.c (xenXMDomainConfigParse): Don't increment it.

* src/network_driver.c (networkSetAutostart): ...and its decl.

* src/iptables.c (iptablesAddRemoveRule): Remove dead store.

* src/util.c (virExecDaemonize): Change flag |= VAR to "flag | VAR".

* src/domain_conf.c (virDomainSaveXML): Remove use and decl of "err".
(virDomainDefParseXML): Likewise.

* src/xm_internal.c (xenXMDomainCreate): Remove dead stores.

* src/xm_internal.c (xenXMDomainConfigParse): Remove declaration
and useless containing if-block, too.

* src/vbox/vbox_tmpl.c: minor bug in selecting the graphics type. if the
  graphics type was desktop it was assumed that display is set for it,
  and thus crashed on strdup. Also adds a number of missing OOM checks.

* src/network_conf.c (virNetworkDefParseXML): ...and its decl.

* src/openvz_driver.c (openvzGenerateContainerVethName): Remove use
and decl of "err".

* src/xend_internal.c (xenDaemonCreateXML): Don't set "ret" after
last use.

* src/storage_driver.c (storagePoolGetInfo, storagePoolDefine):
Remove variable, backend, since its value was never used.

* src/openvz_conf.c src/qemu_driver.c src/storage_backend_scsi.c
  src/xen_inotify.c: closes various file descriptors leaks

* src/lxc_container.c (lxcContainerMountBasicFS): Don't leak upon failure.
Add "cleanup:" label and change each post-allocation failure to
use "goto cleanup" rather than returning immediately.

* src/qemu_conf.c (qemuBuildHostNetStr): Do not remove the type_sep=','
dead store, since not having it would be a problem if we ever add a
new attribute=VAL option.
