Victor Julien db0f9ddc69 files/tx: inspection, logging and loop optimizations 
Introduce AppLayerTxData::file_tx as direction(s) indicator for transactions.
When set to 0, its not a file tx and it will not be considered for file
inspection, logging and housekeeping tasks.

Various tx loop optimizations in housekeeping and output.

Update the "file capable" app-layers to set the fields based on their
directional file support as well as on the traffic.

Victor Julien 79499e4769 app-layer: move files into transactions 
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.

Jeff Lucovsky 8bfe427a74 rust/detect: Create detect module for rule parsing 
This commit creates a module named "detect" for rule parsing logic. As
part of this commit, detect.rs is moved from its toplevel position into
the new module. Thus, use crate::detect::detect to refer to items within
detect.rs (instead of create::detect).

Eric Leblond 2cc9152fc9 rust/smb: log uuid of interface in dcerpc 
When doing a DCERPC request, we can use the context id to log the
interface that is used. Doing that we can see in one single event
what is the DCERPC interface and opnum that are used. This allows
to have all the information needed to resolve the request to a
function call.

Feature #5413.

Eric Leblond b6f1cf255c rust/smb/dcerpc: parse context id 
As context id is used to know to which variant of the endpoint the
request is done, it is interesting to parse it.

Philippe Antoine e94920b49f smb: do not use tree id to match create request and response 
As an SMB2 async response does not have a tree id, even if
the request has it.

Per spec, MessageId should be enough to identifiy a message request
and response uniquely across all messages that are sent on the same
SMB2 Protocol transport connection.
So, the tree id is redundant anyways.

Philippe Antoine 3de735ae70 ike: log ikev1 tx fields instead of state ones 
As state fields can grow abitrarily, and this can lead to DOS
by quadratic complexity (CPU time and disk space)

Adds a direction field to retain all the information in the
transaction.

Also checks array vendor_ids had at least one element before
logging it.

Jason Ish c862e84c01 rust/frames: cleanups 
- Implement the Display trait on Direction to print "toserver" or
  "toclient" which used in a format string.

- Use Direction struct inside Frame instead of a u32.  Requires a helper
  method as there are two representation in C for direction, and the C
  methods for frames don't use the internal representation of the
  Direction enum (some sweeping changes could help here)

Jason Ish f92708b8ca rust/frames: derive direction from StreamSlice 
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.
