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.
