75ecfd2521 qemuBuildControllerDevStr: remove nusbcontroller argument
Now that it's no longer needed, remove the argument.
This removes the last helper variable in
qemuBuildControllerDevCommandLine.

8f5e50e003 qemu: separate counting of USB controllers
qemuBuildLegacyUSBControllerCommandLine is the only place where
we need to count the USB controllers.

Count them again instead of keeping track in a variable passed to
qemuBuildControllerDevStr.

This removes the need for another variable in the loop in
qemuBuildControllerDevCommandLine.

c2a8256991 virPortAllocatorSetUsed: ignore port 0
Similar to what commit 86dba8f3 did for virPortAllocatorRelease,
ignore port 0 in virPortAllocatorSetUsed.

For all the reasonable use cases the callers already check that
the port is non-zero, however if the port from the XML overflows
unsigned short and turns into 0, it can be set as used by
virPortAllocatorSetUsed but not released by virPortAllocatorRelease.

Also skip port '0' in virPortAllocatorSetUsed to make this behavior
symmetric.

The serenity was disturbed by commit 5dbda5e9 which started using
virPortAllocatorRelease instead of virPortAllocatorSetUsed (false).

f80eae8c2a qemu: command: Don't format image properties for empty -drive
If a -drive has no image, using image properties makes qemu whine that
they should not be used.

This patch stops formating cache/readonly/... for empty drives
for the pre-blockdev syntax. Unfortunately those parameters can't be
added later when inserting media, but on the other hand qemu will start
with an empty drive.

Since we already were able to start a VM with such config previously due
to qemu ignoring them I've opted just to skip formatting them.
Additionally with -blockdev support it will work as expected as the
image properties will be formatted when adding the image itself which is
not possible without it.
