Provide backward compatibility with the previous configuration

The commit adds docs about the new format and the introduced changes.
ICE card (Intel E810) was not receiving packets immediatelly
after startup, Suricata workers would act as processing while
it was not. This eliminates the problem by only continuing
in the initialization if the link is already up.
The setting can be turned off manually from the configuraiton
file.

When the packet load is low, Suricata can run in interrupt
mode. This more resembles the classic approach of processing
packets - CPU cores run low and only fetch packets
on interrupt.

Previous integration of hugepage analysis only fetched data
from /proc/meminfo. However this proved to be often
deceiving mainly for providing only global information and
not taking into account different hugepage sizes (e.g. 1GB
hugepages) and different NUMA nodes.
