Now that every caller is using virDomainObjListFindByUUIDRef,
let's just remove it and keep the name as virDomainObjListFindByUUID.

Use bool instead of an int.

Right-aligning backslashes when defining macros or using complex
commands in Makefiles looks cute, but as soon as any changes is
required to the code you end up with either distractingly broken
alignment or unnecessarily big diffs where most of the changes
are just pushing all backslashes a few characters to one side.

In libxl driver we do virObjectRef in libxlDomainObjBeginJob,
If virCondWaitUntil failed, it goes to error, do virObjectUnref,
There's a chance that someone undefine the vm at the same time,
and refs unref to zero, vm is freed in libxlDomainObjBeginJob.
But the vm outside function is not Null, we do virObjectUnlock(vm).
That's how we overwrite the vm memory after it's freed. I fix it.

A pretty nasty deadlock occurs while trying to rename a VM in parallel
with virDomainObjListNumOfDomains.
The short description of the problem is as follows:

Thread #1:

qemuDomainRename:
    ------> aquires domain lock by qemuDomObjFromDomain
       ---------> waits for domain list lock in any of the listed functions:
          - virDomainObjListFindByName
          - virDomainObjListRenameAddNew
          - virDomainObjListRenameRemove

Thread #2:

virDomainObjListNumOfDomains:
    ------> aquires domain list lock
       ---------> waits for domain lock in virDomainObjListCount

Introduce generic virDomainObjListRename function for renaming domains.
It aquires list lock in right order to avoid deadlock. Callback is used
to make driver specific domain updates.

Our domain_conf.* files are big enough. Not only they contain XML
parsing code, but they served as a storage of all functions whose
name is virDomain prefixed. This is just wrong as it gathers not
related functions (and modules) into one big file which is then
harder to maintain. Split virDomainObjList module into a separate
file called virdomainobjlist.[ch].
