The function documentation for state_storage_file_buckets_init() is not

state: backend_storage: Rename variable desired_copies to desired_buckets
...
We defined what a bucket is, so rename the variable that holds the
number of desired buckets from desired_copies to desired_buckets.
While at it, make locally used variable static.

Default to the new circular storage format which saves erase
cycles. The old format can still be selected with
backend-storage-type = "noncircular".

state: bucket: Make output more informative
...
Print offset and number of the bucket along with the bucket
specific messages to give a hint which bucket a message is for.
Also it's pretty much expected that buckets sometimes have no
data or need cleanup, so instead of complaining loudly, only
write which bucket is used and which buckets are cleaned up.

state: Drop cache bucket
...
The cache bucket sits between the storage functions and the backend
storage. We only read from the storage once, so there is no need to cache
anything. The real purpose of the cache bucket is to keep the -EUCLEAN
information when a NAND block needs to be rewritten and to keep the read
buffers as long as the backend iterates over all buckets trying to find
the one we want to use.
This can be coded easier and more obvious in the backend code, so drop
the cache bucket.

state: Convert all bufs to void *
...
A void * is a much better type for a buffer than a u8 * as it
can be casted to any other type implicitly. Convert all buffers
used by the state framework to void *.

state: replace len_hint logic
...
The len_hint mechanism is rather hard to understand as it's not clear
from where to where the hint is passed and also it's not clear what
happens if the hint is empty or wrong.

state: simplify direct backend
...
- drop support for regular files. This, if at all, is only useful for
debugging. For the debugging case still a file of sufficient size
can be created manually.
- make stridesize mandatory. Makes the code simpler.

state: drop lazy_init
...
lazy_init is an optimization that makes it possible to read only up to
the first valid bucket when starting. However, when restoring consistency,
immediately afterwards we have we have to initialize all buckets anyway,
so being lazy doesn't give us any gain. Remove it to simplify the code.
