Instead of using token pasting to generate methods for each superblock
section, just make the type a parameter to bch2_sb_field_get().

Prep work for introducing bch_sb_field_members_v2 - introduce new
helpers that will check for members_v2 if it exists, otherwise using v1

This adds private error codes for most (but not all) of our ENOMEM uses,
which makes it easier to track down assorted allocation failures.

- Fix a sleeping-in-atomic bug due to calling
bch2_journal_buckets_to_sb() under the journal lock.
- Additionally, now we mark buckets as journal buckets before adding
them to the journal in memory and the superblock. This ensures that
if we crash part way through we'll never be writing to journal
buckets that aren't marked correctly.

We shouldn't be overloading standard error codes now that we have
provisions for bcachefs-specific errorcodes: this patch converts super.c
and super-io.c to per error site errcodes, with a bit of cleanup.

checkpatch.pl gives lots of warnings that we don't want - suggested
ignore list:
ASSIGN_IN_IF
UNSPECIFIED_INT - bcachefs coding style prefers single token type names
NEW_TYPEDEFS - typedefs are occasionally good
FUNCTION_ARGUMENTS - we prefer to look at functions in .c files
(hopefully with docbook documentation), not .h
file prototypes
MULTISTATEMENT_MACRO_USE_DO_WHILE
- we have _many_ x-macros and other macros where
we can't do this

Continuing the saga of introducing private dedicated error codes for
each error path, this patch converts ENOSPC to error codes that are
subtypes of ENOSPC. We've recently had a test failure where we got
-ENOSPC where we shouldn't have, and didn't have enough information to
tell where it came from, so this patch will solve that problem.

This converts bcachefs to the modern printbuf interface/implementation,
synced with the version to be submitted upstream.

Add a new superblock field which represents journal buckets as ranges:
also move code for the superblock journal fields to journal_sb.c.
This also reworks the code for resizing the journal to write the new
superblock before using the new journal buckets, and thus be a bit
safer.
