The events would normally be triggered only if we're changing domain
state. But most of the time the domain is already in the right state and
we're just changing its substate from {PAUSED,RUNNING}_POSTCOPY to
*_POSTCOPY_FAILED. Let's emit lifecycle events explicitly when post-copy
migration fails to make the failure visible without polling.

'STREQ' is used to compare the override alias with the device alias.
While the parser ensures that the override alias is non-NULL, the device
alias may be NULL and STREQ doesn't handle that.

We need to use the 'name' variable and just overwrite it with the FD
number when FDs are passed on the monitor. Otherwise we will read NULL
path if the FD is accessed before being passed on the monitor. The idea
of this helper is to simplify the monitor code so it would be
counterproductive to have other behaviour.

Obtaining a screenshot via virDomainScreenshot() works like this:
1) we create a temp file, label it, then
2) tell QEMU to store the screenshot into it, and
3) finally, open the file for transfer via virStream
Since the file is just temporary and even explicitly unlinked at
the end, no seclabel restoration is done. This makes perfect
sense for security models which attach a label to file itself
(DAC, SELinux) because the label is gone with the file. However,
for models where a list of files and allowed actions is kept on a
side (AppArmor) this approach means we just append files into the
profile and never remove them. In turn, the file grows and policy
update takes longer with each entry.
Restore the seclabel for AppArmor's sake.

The virStorageSourceGetActualType() function returns either
virStorageSource->type (which is of type virStorageType), or
virStorageSourcePoolDef->type, which really stores a value of the
same enum. Thus, the latter struct can be changed so that the
virStorageSourceGetActualType() function can return correct type
instead of generic int.

There are three places (two in domain_conf.c and one in
qemu_migration.c) where a virStorageSource->type is typecasted to
virStorageType (for the purpose of catching missing enum member
in a switch() statement at compile time). This is needless,
because as of v8.2.0-rc1~120 the struct member is of proper type.

'virNetMessageEncodePayloadRaw' is not supposed to be called with 'NULL'
data, but the code path from 'virNetClientStreamSendPacket' does so.
Now 'virNetMessageEncodePayloadEmpty' is intended for such case, but
since it's just a sub-set of steps from 'virNetMessageEncodePayloadRaw'
it's more straightforward to add NULL-tolerance to 'virNetMessageEncodePayloadRaw'
and subsequently remove 'virNetMessageEncodePayloadEmpty'.
