Rather than an empty failed to find, let's provide a bit more
knowledge about what we failed to find by using the name string
or the id value.

Rather than repeat code throughout, create and use a couple of
accessors in order to lookup by UUID. This will also generate
a common error message including the failed uuidstr for lookup
rather than just returning nothing in some instances.

The virDomainObjListFindByName will return a locked and reffed
object. If we call virDomainObjListRemove that will unlock the
object upon return, thus we need to relock the object before
making the call to virDomainObjEndAPI.

There's no need to check if @dom exists before trying to
call virDomainObjListRemove since it must exist due to
prior checks.
Additionally, if we do remove the @dom, then set it to NULL
so that the virObjectUnlock isn't referencing something that
is deleted.

If @log is not fopen'd then, going to cleanup and calling fclose
will make for an unhappy callee. So just fail immediately instead
since there's nothing to clean up.

Commit id '43f2ccdc' called virDomainDiskSourceDefFormatInternal
rather than formatting the the disk source inline. However, it
did not handle the case where the helper failed. Over time the
helper has been renamed to virDomainDiskSourceFormat. Similar to
other consumers, if virDomainDiskSourceFormat fails, then the
formatting could be off, so it's better to fail than to continue
on with some possibly bad data. Alter the function and the caller
to check status and jump to error in that case.

The current private XML parsing code relies on the assumption
that NUMA node IDs start from 0 and are densely allocated,
neither of which is necessarily the case.
Change it so that the bitmap size is dynamically calculated by
looking at NUMA node IDs instead, which ensures all nodes will
be able to fit and thus the bitmap will be parsed successfully.
Update one of the test cases so that it would fail with the
previous approach, but passes with the new one.

vircapstest has code to add a full host NUMA topology, that
is, one that includes all information about nodes and CPUs
including IDs; testQemuCapsInit(), which is used to create a
mock virCapsPtr for QEMU tests, however, just fakes it by
setting nnumaCell_max to some number.
While the latter approach has served us well so far, we're
going to need all the information to be filled in soon. In
order to do that, we can just move the existing code from
vircapstest to testutils and, with some renaming and
trivial tweaking, use it as-is.
Interestingly, the NUMA topology generated by the function
is rigged up so that the NUMA nodes aren't (necessarily)
numbered starting from 0, which is a nice way to spot
mistaken assumptions in our codebase.
