In some cases we want to prepare a @src which is not meant to belong to
a disk and thus does not require us to copy the data. Allow passing in
NULL @disk into qemuDomainPrepareDiskSourceData.

qemuDomainPrepareDiskSourceData historically prepared everything but
we've split out the majority of the functionality so that it sets up
predominately only according to the configuration of the disk. There
was one leftover bit of setting the gluster debug level from the config.
Split this out into a separate function so that
qemuDomainPrepareDiskSourceData only prepares based on the disk.

We don't allow such config in the schema but the code can handle that so

The disk type is not part of source and thus it's parsed earlier. This
bypasses the checks when parsing a disk type='network' if it's
completely missing the source.
Since there are possible active users of this (it was reported as a
problem with openstack) fix it by resetting the disk type to '_FILE' for
an empty cdrom which is handled correctly.

The @freeTmpPath boolean is used to determine if @tmpPath holds
an allocated memory or is a pointer to a constant string and
therefore if it needs to be freed or not when returning from the
function. Well, we can unify the way we set @tmpPath so that it
always holds an allocated memory and thus always must be freed.

There are three cases where vir*DeviceGetPath() returns a const
string. In these cases, the string is initialized in
corresponding vir*DeviceNew() calls which fail if string couldn't
be allocated. There's no point in checking the second time if the
string is NULL.

There are two types of host devices that require /dev/vfio/vfio
