David Sterba 1f5094bb5c btrfs-progs: add support for raid1c3 and raid1c4
Add support for 3- and 4- copy variants of RAID1. This adds resiliency
against 2 or resp. 3 devices lost or damaged.

Vladimir Panteleev f972ef650b btrfs-progs: balance: check for full-balance before background fork
Move the full-balance warning to before the fork, so that the user can
see and react to it.

Notes on test:

- Don't use grep -q, as it causes a SIGPIPE during the countdown, and
  the balance thus doesn't start.

- The "balance cancel" is superfluous as the last command, but it
  provides some idempotence and allows adding more tests below it.

Issue: #168
