Workaround function missing in libhtp include
As reported in bug #688, htp_config_set_path_decode_u_encoding
function is not included in libhtp header before 0.3.0. Result
is that suricata compilation fail with an external htp library.
The following patch detect the issue and adds the missing
declaration.

Added host buffer allowance and stream configuration for Napatech 3GD
Added a napatech section in the yaml configuration.
hba - host buffer allowance
use-all-streams - whether all streams should be used
streams - list of stream numbers to use when use-all-streams is no
The source-napatech.* files were modified to support the host buffer allowance configuration.
The runmode-napatech.c file was modified to support both the host buffer allowance configuration and stream configuration

pcap: add snaplen YAML variable
This patch introduces 'snaplen' a new YAML variable in the pcap section.
It can be set per-interface to force pcap capture snaplen. If not set
it defaults to interface MTU if MTU can be known via a ioctl call and to
full capture if not.

pcap: set snaplen to MTU if available.
Main objective of this patch is to use a dynamic snaplen to avoid
to truncate packet at the currently fixed snaplen.
It set snaplen to MTU length if the MTU can be retrieved. If not, it
does not set the snaplen which results in using a 65535 snaplen.
libpcap is trying to use mmaped capture and setup the ring by using buffer_size
as the total memory. It also use "rounded" snaplen as frame size. So if we set
snaplen to MTU when available we are optimal regarding the building of the ring.

Add removal safe TAILQ iterator.
TAILQ_FOREACH macro was not safe for element removal as it was

This macro is removal safe and only differs by a last argument being

Insert pseudo packet under low load conditions to complete rule swap.
This is necessary when we use autofp active packets where most packets
