In a few places we were passing a variable to pr_buf() for the format
string - oops.

This moves validation of superblock options to bch2_sb_validate(), so
they'll be checked in the write path as well.

Now we've got strings for metadata versions - this changes
bch2_sb_to_text() and our mount log message to use it.

Options no longer have to be manually added to bch2_sb_to_text() - it
now uses the master list of options in opts.h. Also, improve some of the
formatting by converting it to tabstops.

This adds a _to_text() pretty printer for journal entries - including
every subtype - which will shortly be used by the 'bcachefs
list_journal' subcommand.

This adds flags for options that must be a power of two (block size and
btree node size), and options that are stored in the superblock as a
power of two (encoded extent max).
Also: options are now stored in memory in the same units they're
displayed in (bytes): we now convert when getting and setting from the
superblock.

This matches the conversion the parsing code does.

This patch converts more enums in the on disk format to our standard
x-macro-with-strings deal - to enable better pretty-printing.

This patch adds subvolume.c - support for the subvolumes and snapshots
btrees and related data types and on disk data structures. The next
patches will start hooking up this new code to existing code.

Add readable names for d_type, and use it in dirent_to_text().

When parsing the mount options duplicate the given options. This is
required as the options are parsed twice and strsep is used in parsing.
The options will be modified into a possibly invalid options set for the
second round of parsing if the options are not duplicated before
parsing.

This patch standardizes all the enums that have associated string tables
(probably more enums should have string tables).

This is to generate strings for them, so that we can print them out.

Some options can't be parsed until the filesystem initialized;
previously, passing these options to mount or remount would cause mount
to fail.
This changes the mount path so that we parse the options passed in
twice, and just ignore any options that can't be parsed the first time.
