qemu: Adjust SCSI controller switch in qemuBuildControllerDevStr

util: Clear unused part of the map in virBitmapShrink
Some of the other functions depend on the fact that unused bits and longs are
always zero and it's less error-prone to clear it than fix the other functions.
It's enough to zero out one piece of the map since we're calling realloc() to
get rid of the rest (and updating map_len).
Since fec8f9c49af we try to use predictable file names for
'memory-backend-file' objects. But that made us provide full path
to qemu when hot plugging the object while previously we provided
merely a directory. But this makes qemu behave differently. If
qemu sees a path terminated with a directory it calls mkstemp()
and unlinks the file immediately. But if it sees full path it
just calls open(path, O_CREAT ..); and never unlinks the file.
Therefore it's up to libvirt to unlink the file and not leave it
behind.

qemu: migration: Refresh device information after transferring state
In my first approach in 4b480d10768c I overlooked the comment in
qemuMigrationRunIncoming stating that during actual migration the
qemuMigrationRunIncoming does not wait until the migration is complete
but rather offloads that to the Finish phase of migration.
This means that during actual migration qemuProcessRefreshState was
called prior to qemu actually transferring the full state and thus the
queries did not get the correct information. The approach worked only
for restore, where we wait for the migration to finish during qemu

Fix the issue by calling qemuProcessRefreshState both from
qemuProcessStart if there's no incomming migration and from
qemuMigrationFinish so that the code actually works as expected.
