Victor Julien 13cebb1857 detect: fix heap overflow issue with buffer setup 
In some cases, the InspectionBufferGet function would be followed by
a failure to set the buffer up, for example due to a HTTP body limit
not yet being reached. Yet each call to InspectionBufferGet would lead
to the matching list_id to be added to the
DetectEngineThreadCtx::inspect.to_clear_queue. This array is sized to
add each list only once, but in this case the same id could be added
multiple times, potentially overflowing the array.

Shivani Bhardwaj 6457754fd6 dcerpc: Replace C function calls with Rust 
All the dead code in C after the Rust implementation is hereby removed.
Invalid/migrated tests have also been deleted.
All the function calls in C have been replaced with appropriate calls to
Rust functions. Same has been done for smb/detect.rs as a part of this
migration.

Anoop Saldanha 429c6388f6 App layer API rewritten. The main files in question are: 
app-layer.[ch], app-layer-detect-proto.[ch] and app-layer-parser.[ch].

Things addressed in this commit:
- Brings out a proper separation between protocol detection phase and the
  parser phase.
- The dns app layer now is registered such that we don't use "dnstcp" and
  "dnsudp" in the rules.  A user who previously wrote a rule like this -

  "alert dnstcp....." or
  "alert dnsudp....."

  would now have to use,

  alert dns (ipproto:tcp;) or
  alert udp (app-layer-protocol:dns;) or
  alert ip (ipproto:udp; app-layer-protocol:dns;)

  The same rules extend to other another such protocol, dcerpc.
- The app layer parser api now takes in the ipproto while registering
  callbacks.
- The app inspection/detection engine also takes an ipproto.
- All app layer parser functions now take direction as STREAM_TOSERVER or
  STREAM_TOCLIENT, as opposed to 0 or 1, which was taken by some of the
  functions.
- FlowInitialize() and FlowRecycle() now resets proto to 0.  This is
  needed by unittests, which would try to clean the flow, and that would
  call the api, AppLayerParserCleanupParserState(), which would try to
  clean the app state, but the app layer now needs an ipproto to figure
  out which api to internally call to clean the state, and if the ipproto
  is 0, it would return without trying to clean the state.
- A lot of unittests are now updated where if they are using a flow and
  they need to use the app layer, we would set a flow ipproto.
- The "app-layer" section in the yaml conf has also been updated as well.

Eric Leblond cd3e32ce19 unittests: some functions needs a flow lock. 
In debug validation mode, it is required to call application layer
parsing and other functions with a lock on flow. This patch updates
the code to do so.

Victor Julien 06904c9024 App Layer cleanup 
Removal of per flow 'aldata' array. It contained a ptr for each ALPROTO. Instead now we have 2 ptrs in the flow: alparser and alstate.
Various cleanups and dead code removal from the app layer API.
Should safe 100+ bytes memory per flow on 64 bit.
Updated lots of unittests to reflect these changes.
