[PATCH 0/2] btrfs-progs: check: enhanced progress indicator

["Stéphane Lesimple" <stephane_btrfs@lesimple.fr>]

This patch replaces the current ".oOo."-style progress indicator of
btrfs check (-p), by a more helpful live indication of the check progress.
I've been using it on a custom btrfs-progs version since 2015.

Here's how the output looks like on a 22 Tb 5-disk RAID1 FS:

# btrfs check -p /dev/mapper/luks-ST10000VN0004-XXXXXXXX
