Philippe Antoine eb5b927787 ssh: fixing incomplete kex parsing 
We use the record length from the ssh record header,
and not the size of the parsed data, as is done in other places.

Victor Julien bcd416e6ba nfs: fix 'dangling' files in lossy sessions 
In case of lossy connections the NFS state would properly clean up
transactions, including file transactions. However for files the
state was never set to 'truncated', leading to files to stay 'active'.

This would lead these files staying in the NFS's state. In long running
sessions with lots of files this would lead to performance and memory
use issues.

This patch cleans truncates the file that was being transmitted when
a file transaction is being closed.

Shivani Bhardwaj bab497ab2c dcerpc: Add multi transaction support 
DCERPC parser so far provided support for single transactions only.
Extend that to support multiple transactions.

In order for multiple transactions to work, there is always a
transaction identifier for any protocol in its header that lets a
response match the request. In DCERPC, for TCP, that param is call_id in
the header which is a 32 bit field. For UDP, however since it uses
different version of RPC (4.x), this is defined by serial number field
defined in the header. This field however is not contiguous and needs to
be assembled by the provided serial_low and serial_hi fields.

Jason Ish 7ca24041b6 rust: add doc target to build rust docs 
Uses "cargo doc --no-deps" to build the documentation just for
our Suricata package. Without --no-deps, documentation will be
build for all our dependencies as well.

The generated documentation will end up in target/doc as HTML.

and what one example of trying to continue might look like.

Jason Ish 53aa967e0b applayer: add flags to parser registration struct 
This will allow Rust parsers to register for gap handing from
Rust (some Rust parsers do handle gaps, but they set the flag
from C).

Victor Julien 5665fc8301 app-layer: add ApplyTxConfig API 
Optional callback a parser can register for applying configuration
to the 'transaction'. Most parsers have a bidirectional tx. For those
parsers that have different types of transaction handling, this new
callback can be used to properly apply the config.

Victor Julien c797c9f09c app-layer: add logger flags to AppLayerTxData 5 years ago
Victor Julien 411f428a38 app-layer: define AppLayerTxData and AppLayerTxConfig 
AppLayerTxData is a structure each tx should include that will contain
the common fields the engine needs for tracking logging, detection and
possibly other things.

AppLayerTxConfig will be used by the detection engine to configure
the transaction.
