If the compression program for external snapshot memory image isn't
found we exitted the function without terminating the domain job. This
caused the domain to be unusable.

The problem was introduced in commit 7df5093f.

Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1097503

Move sharable PCI handling functions to domain_addr.[ch], and
change theirs prefix from 'qemu' to 'vir':

 - virDomainPCIAddressAsString;
 - virDomainPCIAddressBusSetModel;
 - virDomainPCIAddressEnsureAddr;
 - virDomainPCIAddressFlagsCompatible;
 - virDomainPCIAddressGetNextSlot;
 - virDomainPCIAddressReleaseSlot;
 - virDomainPCIAddressReserveAddr;
 - virDomainPCIAddressReserveNextSlot;
 - virDomainPCIAddressReserveSlot;
 - virDomainPCIAddressSetFree;
 - virDomainPCIAddressSetGrow;
 - virDomainPCIAddressSlotInUse;
 - virDomainPCIAddressValidate;

The only change here is function names, the implementation itself
stays untouched.

Extract common allocation code from DomainPCIAddressSetCreate
into virDomainPCIAddressSetAlloc.

Introduce new files (domain_addr.[ch]) to provide
an API for domain device handling that could be
shared across the drivers.

A list of data types were extracted and moved there:

 qemuDomainPCIAddressBus -> virDomainPCIAddressBus
 qemuDomainPCIAddressBusPtr -> virDomainPCIAddressBusPtr
 _qemuDomainPCIAddressSet -> virDomainPCIAddressSet
 qemuDomainPCIAddressSetPtr -> virDomainPCIAddressSetPtr
 qemuDomainPCIConnectFlags -> virDomainPCIConnectFlags

Also, move the related definitions and macros.

If qemuDomainBlockResize() is passed a size not on a KiB boundary - that
is passed a size based in bytes (VIR_DOMAIN_BLOCK_RESIZE_BYTES), then
depending on the source format (qcow2 or qed), the value passed must
be on a sector (or 512 byte) boundary. Since other libvirt code quietly
adjusts the capacity values, then do so here as well.

This reverts commit e3d66229.

Commit 9976c4b9 broke the output for VNC
displays as the port number is converted to VNC display number by
subtracting 5900. This yields port 0 for the first display and thus the
output would be skipped.

Before:
 $ virsh domdisplay VM
 vnc://localhost

After:
 $ tools/virsh domdisplay VM
 vnc://localhost:0

When a domain was started without registration in sanlock, but libvirt
was restarted after that, most of the operations failed due to
contacting sanlock about that process.  E.g. migration could not be
performed because the locks couldn't be released (or inquired before a
release).

Our documentation generator is a bit messy, to say the least. For
instance, the description to return values of a function is
searched within C comment. Currently, all lines that start with
'returns' or 'Returns' are viewed as return value description.
However, there are some valid uses where the 'returns' word is in
the middle of a sentence describing function behavior not the
return value. And there are no places where 'returns' is used to
describe return values.  For instance:
virDomainDetachDeviceFlags, virConnectNetworkEventRegisterAny and
virDomainGetDiskErrors. This leads to HTML documemtation being
generated incorrectly.

Since the ESX storage implements VMFS and iSCSI storage backends and
chooses relevant backend dynamically at runtime, there was a segfault
when issuing vol-info on iSCSI volume due to unimplemented
virStorageGetInfo function. This patch implements that function that was
missing in iSCSI backend and returns expected result without a segfault.

Refactoring in commit id '0c2305b3' resulted in the wrong storage
volume object being passed to the new storageVolDeleteInternal().
It should have passed 'voldef' which is the address found in the
pool->volumes.objs[i] array.  By passing 'voldef', the DeleteInternal
code will find and remove the voldef from the volumes.objs[] list.

There is a problem with function parallelsDomainDefineXML. If we
are defining a new domain, then we need to do 2 things: aclually
create a VM in PCS and add new domain to the cached list of domains
_parallelsConn.domains.

This is done in the function parallelsLoadDomains. So call to
virDomainObjListAdd will return a error, because a domain
with the same name and id will already be in the list.

I added this code year ago, instead of implementing ability
to change VNC configuration, which was not trivial, I added
extra call to prlctl, which sets up VNC with auto port, despite
VNC configuration given by a user.

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.

QEMU commit 5e2ac51 added a boolean '-msg timestamp=[on|off]'
option, which can enable timestamps on errors:
$ qemu-system-x86_64 -msg timestamp=on zghhdorf
2014-04-09T13:25:46.779484Z qemu-system-x86_64: -msg timestamp=on: could
not open disk image zghhdorf: Could not open 'zghhdorf': No such file or
directory

Enable this timestamp if the QEMU binary supports it.

Add a 'log_timestamp' option to qemu.conf for disabling this behavior.

Adds 'quiesced' status into qemuDomainObjPrivate that tracks whether
FSFreeze is requested in the domain.

It modifies error code from qemuDomainSnapshotFSFreeze and
qemuDomainSnapshotFSThaw, so that a caller can know whether the command is
actually sent to the guest agent. If the error is caused before sending a
freeze command, a counterpart thaw command shouldn't be sent either, not to
confuse fsfreeze status tracking.
