Jim Harris d84a88c1a0 bdev: add base infrastructure for locked lba ranges
This adds new internal APIs bdev_lock_lba_range and
bdev_unlock_lba_range.  To start, these APIs will
manage dissemination of lock/unlock requests to all
existing channels for a given bdev.  This does not
yet interact at all with any I/O sent to the channel.

Future patches will check new I/O to see if they
are trying to write to a range that is locked.  Future
patches will also ensure we do not have overlapping
ranges active at once.
