Calling the monitor was convenient for the implementation in
qemuDomainBlockCopyCommon, but causes the snapshot code to call
query-named-block-nodes for every disk.
Fix this by removing the monitor call from
qemuBlockStorageSourceCreateDetectSize so that the data can be reused in
loops.

Add a simpler constructor for hash tables which specifically does not
require specifying the initial hash size and uses simpler freeing
function.
The initial hash table size usually is not important as the hash table
is growing when it reaches certain number of entries in one bucket.
Additionally many callers pass in a random small number for ad-hoc table
use so using a central one will simplify things.

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.

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

corresponding vir*DeviceNew() calls which fail if string couldn't
be allocated. There's no point in checking the second time if the
