Add the __counted_by compiler attribute to the flexible array member b
to improve access bounds-checking via CONFIG_UBSAN_BOUNDS and
CONFIG_FORTIFY_SOURCE.
Use struct_size() to calculate the number of bytes to be allocated.
Update bucket_gens->nbuckets and bucket_gens->nbuckets_minus_first when
resizing.
Compile-tested only.

This will help with some of the btree_trans srcu lock hold time warnings
that are still turning up; submit_bio() can block for awhile if the
device is sufficiently congested.
It's not a perfect solution since blk_plug bios are submitted when
scheduling; we might want a way to disable the "submit on context
switch" behaviour, or switch to our own plugging in the future.

This part of addressing
https://github.com/koverstreet/bcachefs/issues/656
where we're getting stuck in bch2_journal_meta() in the dump tool.
We shouldn't be invoking the journal without a ref on c->writes (if
we're not RW), and there's no reason for the dump tool to be going
read-write.

-o norecovery (used by the dump tool) should be doing the absolute
minimum amount of work to get the filesystem up and readable; we
shouldn't be running check and repair code, or going read-write.

We need to add a path for reshaping existing stripes (for e.g. device
removal), and this new path won't necessarily use ec_stripe_head.
Refactor the code to avoid unnecessary references to it for clarity.

Recovery can rewind in certain situations - when we discover we need to
run a pass that doesn't normally run.
This can happen from another thread for btree node read errors, so we
need a bit of locking.

They can be regenerated by fsck and don't require a btree node scan,

if we're not in recovery then there's no way to rewind recovery - give
this a different errcode so that any error messages will give us a
better idea of what happened.

A series posted previously moved all of the `struct xattr_handler`
tables to .rodata for each filesystem [1].
However, this appears to have been done shortly before bcachefs was
merged, so bcachefs was missed at that time.
