btrfs: introduce RAID1 round-robin read balancing
Add round-robin read policy that balances reads over available devices
(all RAID1 block group profiles). Switch to the next devices is done
after a number of blocks is read, which is 256K by default and is
configurable in sysfs.
The format is "round-robin:<min-contig-read>" and can be set in file
/sys/fs/btrfs/FSID/read_policy
