ea18f8b2b0 maint: use enum typedef for virstorageencryption.h
Continuing the work of consistent enum cleanups; this time in
virstorageencryption.h.

* src/util/virstorageencryption.h (virStorageEncryptionFormat):
Convert to typedef, renaming to avoid collision with function.
(virStorageEncryptionSecret, virStorageEncryption): Directly use
enums.

6f9c75a6f7 qemu: Implement virDomain{Get,Set}Time
One caveat though, qemu-ga is expecting time and returning time
in nanoseconds. With all the buffering and propagation delay, the
time is already wrong once it gets to the qemu-ga, but there's
nothing we can do about it.

0abb369380 Introduce virDomain{Get,Set}Time APIs
These APIs allow users to get or set time in a domain, which may come
handy if the domain has been resumed just recently and NTP is not
configured or hasn't kicked in yet and the guest is running
something time critical. In addition, NTP may refuse to re-set the clock
if the skew is too big.

In addition, new ACL attribute is introduced 'set_time'.

cc4882f4ab qemu: Ignore temporary job errors when checking migration status
When qemu driver is polling for migration to finish (in
qemuMigrationWaitForCompletion), it may happen that another job allowed
during migration is running and if it does not finish within 30 seconds,
migration would be cancelled because of that. However, we can just
ignore the timeout and let the waiting loop try again later.

If an event fired at the end of migration is ever implemented in QEMU,
we can just wait for the event instead of polling for migration status
and libvirt will behave consistently, i.e., migration won't be cancelled
in case another job started during migration takes long time to finish.

I added this code year ago, instead of implementing ability

Let's remove this hack, because, first, it doesn't work on the
latest Parallels Cloud Server release (you have to either specify
--vnc-nopasswd option or password). And also has problem with
error handling. If second call to prlctl fails, VM, created by
first call to prlctl, will not be removed.

1e947cf7d8 qemu: specify domain in host-side PCI addresses when needed/supported
This uses the new QEMU_CAPS_HOST_PCI_MULTIDOMAIN capability when
present, for -devivce pci-assign, -device vfio-pci, and -pcidevice.

While creating tests for this new functionality, I noticed that the
xmls for two existing tests had erroneously specified an
until-now-ignored domain="0x0002", so I corrected those two tests, and
also added two failure tests to be sure that we alert users who
attempt to use a non-zero domain with a qemu that doesn't support it.

17133e3702 qemu: add host-pci-multidomain capability
Quite a long time ago, (apparently between qemu 0.12 and 0.13) qemu
quietly began supporting the optional specification of a domain in the
host-side address of all pci passthrough commands (by simply
prepending it to the bus:slot.function format, as
"dddd:bb:ss.f"). Since machines with multiple PCI domains are very
rare, this never came up in practice, so libvirt was never updated to
support it.

This patch takes the first step to supporting specification of a non-0
domain in the host-side address of PCI devices being assigned to a
domain, by adding a capability bit to indicate support
"QEMU_CAPS_HOST_PCI_MULTIDOMAIN", and detect it. Since this support
was added in a version prior to the minimum version required for
QMP-style capabilities detection, the capability is always enabled for
any qemu that uses QMP for capabilities detection. For older qemus,
the only clue that a domain can be specified in the host pci address
is the presence of the string "[seg:]" in the help string for
-pcidevice. (Ironically, libvirt will not be modified to support
specification of domain for -pcidevice, since any qemu new enough for
us to care about also supports "-device pci-assign" or "-device
vfio-pci", which are greatly preferred).

eb54426659 storageVolCreateXMLFrom: Allow multiple accesses to origvol
When creating a new volume, it is possible to copy data into it from
another already existing volume (referred to as @origvol). Obviously,
the read-only access to @origvol is required, which is thread safe
(probably not performance-wise though). However, with current code
both @newvol and @origvol are marked as building for the time of
copying data from the @origvol to @newvol. The rationale behind
is to disallow some operations on both @origvol and @newvol, e.g.
vol-wipe, vol-delete, vol-download. While it makes sense to not allow
such operations on partly copied mirror, but it doesn't make sense to
disallow vol-create or vol-download on the source (@origvol).
