This patch fixes the following issue reported by valgrind:
31 errors in context 1 of 1:
Conditional jump or move depends on uninitialised value(s)

The running field in PcapCommand was not initialized.
This patch fixes an issue in unix socket handling. It is possible
that a socket did disconnect when analysing a command and because
the data treatment is done in a loop on clients this was leading
to a update of the list of clients during the loop. So we need
in fact to use TAILQ_FOREACH_SAFE instead of TAILQ_FOREACH.

It is possible to have a non-contiguous CPU set, which was not being
handled correctly on the TILE architecture.
Added a "rank" field in the ThreadVar to store the worker's rank separately
from the cpu for this case.
When applying wildcard thresholds (with sid = 0 and/or gid = 0) it's wrong
to exit on the first signature already having an event filter. Indeed,
doing so results in the theshold not being applied to all subsequent
signatures. Change the code in order to skip signatures with event
filters instead of breaking out of the loop.
If a live reload signal was given before the engine was fully started
up (e.g. pcap file thread waiting for a disk to spin up), a segv could
occur.
This patch only enables live reloads after the threads have been
started up completely.
