Gaurav Singh 637a7c8e55 Adds options to mark when a file is final. 
This takes the form of an option to add the pid of the process to file
names. Additionally, it adds a suffix to the file name to indicate it is
not finalized.

Adding the pid to the file name reduces the likelihood that a file is
overwritten when suricata is unexpectedly killed. The number in the
waldo file is only written out during a clean shutdown. In the event
of an improper shutdown, extracted files will be written using the old
number and existing files with the same name will be overwritten.

Writes extracted files and their metadata to a temporary file suffixed
with '.tmp'. Renames the files when they are completely done being
written. As-is there is no way to know that a file on disk is still
being written to by suricata.

Alfredo Cardigliano b6baafb3e3 pfring: hw bypass support 
This patch adds support for hw bypass by enabling flow offload in the network
card (when supported) and implementing the BypassPacketsFlow callback.
Hw bypass support is disabled by default, and can be enabled by setting
"bypass: yes" in the pfring interface configuration section in suricata.yaml.

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}}

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.

Giuseppe Longo 9ab1194f68 modbus: set stream depth
