* 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.

* src/hash.c (virHashFree): Remove useless assignment to inside_table.

* src/interface_conf.c (virInterfaceDefParseDhcp): Remove unused "old".

* tests/eventtest.c (mymain): Exit nonzero upon write failure.
This also avoids several dead stores of the form ret = safewrite...

* src/openvz_conf.c (openvz_copyfile): Remove unused assignment.

* src/storage_backend_logical.c (virStorageBackendLogicalBuildPool):
Don't increment "n" when we won't use the result.

* src/esx/esx_util.c: let esxUtil_GetConfigUUID() report an error if
  virUUIDParse() fails

* src/esx/esx_driver.c: add esxDomainUndefine() based on
  esxVI_UnregisterVM()
* src/esx/esx_vi_methods.[ch]: add esxVI_UnregisterVM()

* src/esx/esx_driver.c: add esxCapsInit() with default caps and add
  esxGetCapabilities()

* src/esx/esx_vi.[ch]: convert esxVI_RemoteRequest_Execute() to a
  simpler esxVI_Context_Execute() version, remove esxVI_RemoteRequest
  and convert esxVI_RemoteResponse to esxVI_Response
* src/esx/esx_vi_methods.c: update and simplify callers to use
  esxVI_Context_Execute() instead of esxVI_RemoteRequest_Execute()

* src/esx/esx_vi.[ch]: use virXPathNode*() in
  esxVI_RemoteRequest_Execute() and remove
  esxVI_RemoteResponse_DeserializeXPathObject*()
* src/esx/esx_vi_methods.c: update callers to use the new syntax of
  esxVI_RemoteRequest_Execute()

* src/esx/esx_driver.c: add configStatus to the requested properties
  to check it in esxVI_GetVirtualMachineIdentity()
* src/esx/esx_vi.[ch]: add esxVI_GetManagedEntityStatus()
  and use it in esxVI_GetVirtualMachineIdentity()
* src/esx/esx_vi_types.[ch]: add VI type esxVI_ManagedEntityStatus

* src/esx/esx_driver.c: handle spaces in VMX file path and use a
  virBuffer to encode spaces correctly in the resulting URL
* src/esx/esx_vi.c: include the URL in the error message in case
  of a download error

* src/vbox/vbox_driver.c src/vbox/vbox_tmpl.c: adds the driver for
  storage volumes

* src/domain_conf.c src/network_conf.c src/qemu_conf.c
  src/storage_backend_fs.c: various problems spotted by valgrind
  through libvirt code

* src/vbox/vbox_tmpl.c: a bit of cleanup

* src/libvirt.c: fix some minor grammer (and one other) nits in comments
  that end up in generated API reference documentation
