Victor Julien 0d79181d78 nfs: rename nfs3 to nfs 
Since the parser now also does nfs2, the name nfs3 became confusing.
As it's still in beta, we can rename so this patch renames all 'nfs3'
logic to simply 'nfs'.

Eric Leblond ea9b9b5063 stream-tcp: add option to accept invalid packets 
Suricata was inconditionaly dropping packets that are invalid with
respect to the streaming engine. In some corner case like asymetric
trafic capture, this was leading to dropping some legitimate trafic.

The async-oneside option did help but this was not perfect in some
real life case. So this patch introduces an option that allow the
user to tell Suricata not to drop packet that are invalid with
respect to streaming.

Eric Leblond 775e67459c filestore: avoid open write close sequence 
Current file storing approach is using a open file, write data,
close file logic. If this technic is fixing the problem of getting
too much open files in Suricata it is not optimal.

Test on a loop shows that open, write, close on a single file is
two time slower than a single open, loop of write, close.

This patch updates the logic by storing the fd in the File structure.
This is done for a certain number of files. If this amount is exceeded
then the previous logic is used.

This patch also adds two counters. First is the number of
currently open files. The second one is the number of time
the open, write, close sequence has been used due to too much
open files.

In EVE, the entries are:
 stats {file_store: {"open_files_max_hit":0,"open_files":5}}

Eric Leblond 54718b306e filestore: add option to disable meta file writing 
As the fileinfo entry is containing the file_id it is enough to
have this entry to link the extracted file with metadata.

Ray Ruvinskiy 7539973109 tls: logging for session resumption 
We assume session resumption has occurred if the Client Hello message
included a session id, we have not seen the server certificate, but
we have seen a Change Cipher Spec message from the server.

Previously, these transactions were not logged at all because the
server cert was never seen.

Jason Ish 82f6103149 unified2: nostamp and file rotation 
Give unified2 a nostamp option which will create the file
without the timestamp suffix (like Snort's nostamp option).

Also register for rotation notification on SIGHUP so the file
will be recreated if it is removed by an external rotation
program (only when nostamp is used).

Victor Julien a0580d8805 stream: initialize stream segment pool from mtu 
If segments section in the yaml is ommitted (default) or when the
pool size is set to 'from_mtu', the size of the pool will be MTU
minus 40. If the MTU couldn't be determined, it's assumed to be
1500, so the segment size for the bool will be 1460.

Jason Ish a6854147be pcap-log config: sguil-base-dir -> dir and update comment 
The code already looks for "dir" first instead of
"squil-base-dir", and already respects this configuration
parameter in other modes than the "sguil" mode.

Coda will still access "sguil-base-dir".

Giuseppe Longo 3f214b506a file-store: add depth setting 
When a rules match and fired filestore we may want
to increase the stream reassembly depth for this specific.

This add the 'depth' setting in file-store config,
which permits to specify how much data we want to reassemble
into a stream.

Giuseppe Longo 9ab1194f68 modbus: set stream depth 
Some protocol like modbus requires
a infinite stream depth because session
are kept open and we want to analyze everything.

Since we have a stream reassembly depth per stream,
we can also set a stream reassembly depth per proto.
