Victor Julien f9155aa121 files: simplify pruning logic 
Since ebcc4db84a the flow worker runs
file pruning after parsing, detection and loging. This means we can
simplify the pruning logic. If a file is in state >= CLOSED, we can
prune it. Detection and outputs will have had a final chance to
process it.

Remove the calls to the pruning code from Rust. They are no longer
needed.

Shivani Bhardwaj 6d39f6fd7d rust: Fix deprecation warnings 
Fix the following warnings by compiler,
(1) warning: use of deprecated item 'take_until_s': Please use `take_until` instead
(2) warning: `...` range patterns are deprecated

For the second warning, the builtin lint
"ellipsis_inclusive_range_pattern" has been added which causes the
following warning to show up with rustc 1.24.

warning: unknown lint: `ellipsis_inclusive_range_patterns`

Victor Julien 422e4892cc proto-detect: improve midstream support 
When Suricata picks up a flow it assumes the first packet is
toserver. In a perfect world without packet loss and where all
sessions neatly start after Suricata itself started, this would be
true. However, in reality we have to account for packet loss and
Suricata starting to get packets for flows already active be for
Suricata is (re)started.

The protocol records on the wire would often be able to tell us more
though. For example in SMB1 and SMB2 records there is a flag that
indicates whether the record is a request or a response. This patch
is enabling the procotol detection engine to utilize this information
to 'reverse' the flow.

There are three ways in which this is supported in this patch:

1. patterns for detection are registered per direction. If the proto
   was not recognized in the traffic direction, and midstream is
   enabled, the pattern set for the opposing direction is also
   evaluated. If that matches, the flow is considered to be in the
   wrong direction and is reversed.

2. probing parsers now have a way to feed back their understanding
   of the flow direction. They are now passed the direction as
   Suricata sees the traffic when calling the probing parsers. The
   parser can then see if its own observation matches that, and
   pass back it's own view to the caller.

3. a new pattern + probing parser set up: probing parsers can now
   be registered with a pattern, so that when the pattern matches
   the probing parser is called as well. The probing parser can
   then provide the protocol detection engine with the direction
   of the traffic.

The process of reversing takes a multi step approach as well:

a. reverse the current packets direction
b. reverse most of the flows direction sensitive flags
c. tag the flow as 'reversed'. This is because the 5 tuple is
   *not* reversed, since it is immutable after the flows creation.

Most of the currently registered parsers benefit already:

- HTTP/SMTP/FTP/TLS patterns are registered per direction already
  so they will benefit from the pattern midstream logic in (1)
  above.

- the Rust based SMB parser uses a mix of pattern + probing parser
  as described in (3) above.

- the NFS detection is purely done by probing parser and is updated
  to consider the direction in that parser.

Other protocols, such as DNS, are still to do.

Victor Julien 0e40231189 app-layer: improve transaction cleanup handling 
The app layers with a custom iterator would skip a tx if during
the ..Cleanup() pass a transaction was removed.

Address this by storing the current index instead of the next
index. Also pass in the next "min_tx_id" to be incremented from
the last TX. Update loops to do this increment.

Also make sure that the min_id is properly updated if the last
TX is removed when out of order.

Finally add a SMB unittest to test this.

Victor Julien 1b1e136c4f nfs: improve file tracking under packet loss

The file tracker would then panic if a new file was opened, as
it noticed the last chunk wasn't yet complete.

This patch tracks the file handle for a in-progress chunk in the
state, just like the tracking of the size that is left.

Maurizio Abba bf4398b15d output-json: ensure string is json-encodable 
Substitute json_string with SCJsonString custom function.
SCJsonString will ensure string passed is json-encodable (utf-8).
If it's not, the string will be converted in such a way that any
non-printable character will be encoded in its hex form.
The resulting json object will be returned.

rust modification will encode any non-printable character during its
conversion in to_cstring.

Victor Julien cb3abba1e0 nfs4: log remove procedure + add multi-proc support 
Add TX creation for NFS4 transactions. Start with the 'REMOVE' procedure.

Start on logging all procs. In NFS4 COMPOUND records there are multiple
procedures. One of them can be considered the 'main' procedure, with others
as supporting utility. This patch adds the first step in supporting to
track those in the TX for logging and inspection.

instead of assuming it sits exactly at the start of the input data.

Jason Ish 9210d8743b rust/dhcp: Rust based DHCP decoder and logger. 
This is a DHCP decoder and logger written in Rust. Unlike most
parsers, this one is stateless so responses are not matched
up to requests by Suricata. However, the output does contain
enough fields to match them up in post-processing.

Rules are included to alert of malformed or truncated options.

Jason Ish 2ec3381600 rust/app-layer: macros to export de_state functions 
These macros generate the extern "C" functions for transactions
structs that need provide functions for setting and getting
the de_state. The idea is to provide macros do avoid code
duplication and make it simpler to create an app-layer.

A trait would be the correct solution, but it doesn't look like
you can use traits to export extern "C" functions.

The parser looks the first two messages of a connection, and analyzes
the client and server proposals to check the cryptographic parameters.

Victor Julien eac7a92200 smb2: improve read/write record parsing 
parse_smb2_response_read()/parse_smb2_response_write() can be called on
incomplete data, so they didn't use the read/write length field to grab
the data field. Instead it just used rest(). However in some cases
SMB2 records have trailing data, which would be included in the
READ/WRITE data.

This patch addresses this by using the length field if enough data is
available.
