Previously stubDriver was always set from a string literal, so it was
okay to use a const char * that wasn't freed when the virPCIDevice was
freed. This will not be the case in the near future, so it is now a
char* that is allocated in virPCIDeviceSetStubDriver() and freed
during virPCIDeviceFree().
I noticed several unusual spacings in for loops, and decided to
fix them up. See the next commit for the syntax check that found
all of these.

Commit '18b14012' refactored the Xen code resulting in a Coverity
warning about possible NULL reference if the path where the XM driver
takes puts the def on it's list. Moved/duplicated the virGetDomain()
call to pacify the possible NULL deref.
Introduce use of a virDomainDefPtr in the domain coredump
APIs to simplify introduction of ACL security checks.
The virDomainPtr cannot be safely used, since the app
may have supplied mis-matching name/uuid/id fields. eg
the name points to domain X, while the uuid points to
domain Y. Resolving the virDomainPtr to a virDomainDefPtr
ensures a consistent name/uuid/id set.

These all existed before virfile.c was created, and for some reason
weren't moved.
This is mostly straightfoward, although the syntax rule prohibiting
write() had to be changed to have an exception for virfile.c instead
of virutil.c.
This movement pointed out that there is a function called
virBuildPath(), and another almost identical function called
virFileBuildPath(). They really should be a single function, which
I'll take care of as soon as I figure out what the arglist should look
like.

The Xen driver uses a macro GET_PRIVATE as a supposed shorthand
for 'xenUnifiedPrivatePtr priv = (xenUnifiedPrivatePtr) (conn)->privateData'.
It does not in fact save any lines of code, and obscures what is
happening. Remove it, since it adds no value.
