This patch improves the superblock .to_text() methods and adds methods
for all types that were missing them. It also improves printbufs by
allowing them to specfiy what units we want to be printing in, and adds
new wrapper methods for unifying our kernel and userspace environments.

This simplifies the code quite a bit and eliminates an inconsistency - a
given bkey doesn't necessarily translate to a single replicas entry for
disk space accounting.

This changes bch2_trans_fs_usage_apply() to handle failure (replicas
entry missing) by reverting the changes it made - meaning we can make
the main transaction commit path a bit slimmer, and perhaps also
simplify some locking in upcoming patches.

This is an important cleanup, eliminating an unnecessary copy in the
transaction commit path.

When the replicas mechanism was added, for tracking data by which drives
it's replicated on, the check for whether we have sufficient devices was
never updated to make use of it. This patch finally does that.

This fixes a bug introduced by "bcachefs: Improve diagnostics when
journal entries are missing" - devices in a replicas entry are supposed
to be sorted.

Awhile back the mechanism for garbage collecting unused replicas entries
was significantly improved, but some cleanup was missed - this patch
does that now.
This is also prep work for a patch to account for erasure coded parity
blocks separately - we need to consolidate the logic for
checking/marking the various replicas entries from one bkey into a
single function.

When disk space accounting was changed to be tracked by replicas entry,
the ioctl interface was never update: this patch finally does that.
Aditionally, the BCH_IOCTL_USAGE ioctl is now broken out into separate
ioctls for filesystem and device usage.

this lets us get rid of a lot of extra switch statements - in a lot of
places we dispatch on the btree node type, and then the key type, so
this is a nice cleanup across a lot of code.
Also improve the on disk format versioning stuff.

Initially forked from drivers/md/bcache, bcachefs is a new copy-on-write
filesystem with every feature you could possibly want.
