73501ab82c bcachefs: Don't use sha256 for siphash str hash key
With the refactoring that's coming to add fuse support, we want
bch2_hash_info_init() to be cheaper so we don't have to rely on anything
cached besides the inode in the btree.

64bc001153 bcachefs: Rework btree iterator lifetimes
The btree_trans struct needs to memoize/cache btree iterators, so that
on transaction restart we don't have to completely redo btree lookups,
and so that we can do them all at once in the correct order when the
transaction had to restart to avoid a deadlock.

This switches the btree iterator lookups to work based on iterator
position, instead of trying to match them up based on the stack trace.

3c5fa33a55 bcachefs: force str_hash code to be inlined
the btree trans iterator stuff relies on a dirty horrible hack that uses
a short backtrace to generate tokens, and gcc uninlining these functions
breaks that hack. ugh.

26609b619f bcachefs: Make bkey types globally unique
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.
