virDomainControllerDefParseXML() does a lot of checks with
virDomainPCIControllerOpts parameters that can be moved to
virDomainControllerDefValidate, sharing the logic with other use
cases that does not rely on XML parsing.
'pseries-default-phb-numa-node' parse error was changed to reflect
the error that is being thrown by qemuValidateDomainDeviceDefController()
via deviceValidateCallback, that is executed before
virDomainControllerDefValidate().

As some users of the incremental backup API want to provide backups in

to define the checkpoint for live use, supplying a <domain> sub-element

While we generally expect libvirt objects to be defined using the
appropriate APIs, there are cases where it's reasonable for an
external entity, usually a package manager, to drop a valid
configuration file under /etc/libvirt and have libvirt take over
from there: notably, this is exactly how the default network is
handled.
For the most part, whether the configuration is saved back to disk
after being parsed by libvirt doesn't matter, because we'll end up
with the same values anyway, but an obvious exception to this is
data that gets randomly generated when not present, namely MAC
address and UUID.
Historically, both were handled by our build system, but commit
a47ae7c004 moved handling of the former inside libvirt proper;
this commit extends such behavior to the latter as well.
Proper error handling for the virNetworkSaveConfig() call, which
was missing until now, is introduced in the process.

The way our domain capabilities work currently, is that we have
virDomainCapsEnum struct which contains 'unsigned int values'
member which serves as a bitmask. More complicated structs are
composed from this struct, giving us whole virDomainCaps
eventually.
Whenever we want to report that a certain value is supported, the
'1 << value' bit is set in the corresponding unsigned int member.
This works as long as the resulting value after bitshift does not
overflow unsigned int. There is a check inside
virDomainCapsEnumSet() which ensures exactly this, but no caller
really checks whether virDomainCapsEnumSet() succeeded. Also,
checking at runtime is a bit too late.
Fortunately, we know the largest value we want to store in each
member, because each enum of ours ends with _LAST member.
Therefore, we can check at build time whether an overflow can
occur.

The function only returns zero or aborts, so it might as well be void.
This has the added benefit of simplifying the code that calls it.

First one prepares and validates the definition, the second one actually
either updates an existing checkpoint or assigns definition for the new
one.
This will allow driver code to add extra validation between those
steps.

Convert all calls to virHashForEach where it's not obvious that the
callback is _not_ deleting the current element from the hash to
virHashForEachSafe which will be deemed safe to do such operation.
Now that no iterator used with virHashForEach deletes current element we
can document that virHashForEach must not touch the hash table in any
way.

All but one of the callers either use the list in arbitrary order or
sorted by key. Rewrite the function so that it supports sorting by key
natively and make it return the element count. This in turn allows to
rewrite the only caller to sort by value internally.
This allows to remove multiple sorting functions which were sorting by
key and the function will be also later reused for some hash operations
internally.
