Update APIs to store files in transactions instead of the per flow state.
Goal is to avoid the overhead of matching up files and transactions in
cases where there are many of both.
Update all protocol implementations to support this.
Update file logging logic to account for having files in transactions. Instead
of it acting separately on file containers, it is now tied into the
transaction logging.
Update the filestore keyword to consider a match if filestore output not
enabled.
On the Rust side, a Frame requires a StreamSlice to be created. We can
derive the direction from the StreamSlice removing the need for callers
to provide the direction when operating on the frame.
Instead of a method that is required to return a slice of transactions,
use 2 methods, one to return the number of transactions in the
collection, and another to get a transaction by its index in the
collection.
This allows for the transaction collection to not be a contiguous array
and instead can be a VecDeque, or possibly another collection type that
supports retrieval by index.
Ticket #5278
With these, the portion of code within the tags should be included
in the related code-snippets (for frame support documentation) w/o
errors, even if the code within changes. The tags can also work as
a reminder that the existing code is being shown elsewhere, so folks
know documentation might need updates, in case of major changes.
When we want to share our code in our documentation pages, the current
rust formatting isn't so nice to read. Formatted just the portion of
the code that will be shown, for now.
