1808159f32 domain_conf: Use virXMLFormatElement() more
I've identified some places (mostly by looking for
virBufferUse()) that can use virXMLFormatElement() instead of
open coded version of it. I'm sure there are many more places
that could use the same treatment. Let's cure them some other
time.

9d225ea284 virDomainDiskDefParseSource: parse source bits from driver element
Before the mentioned commit we always parsed the whole disk definition
for qemuDomainBlockCopy API but we only used the @src part. Based on
that assumption the code was changed to parse only the disk <source>
element.

Unfortunately that is not correct as we need to parse some parts of
<driver> element as well.

a52b74e7a3 conf: new function virDomainNetRemoveByObj()
virDomainNetRemove() requires the index of the net device you want to
remove from the list, but in some cases you may not have the index
handy, only the object itself (or the object may not have been added
to the domain's list). virDomainNetRemoveByObj() first tries to find
the given object in the nets list, and deletes that if it is found.

As with virDomainNetRemove() it always unconditionally tries to remove
the device from the hostdevs list (in case it is the ridiculous
combined net+hostdev device created for <interface type='hostdev'>).

Compilers aren't able to see whether @result is set or not and thus
don't warn of a potential use of uninitialized value. Always set @result
to prevent uninitialized use.

This is done by adding a @defaultResult argument to virXMLPropInt since
many places have a non-0 default.

In certain cases such as in virDomainControllerDefParseXML we pass the
value from the original value, which will still trigger compiler checks
if unused while preserving the existing functionality of keeping the
previous value.

 in virDomainDiskSourceNetworkParse introduced by 38dc25989c
