Victor Julien f68c255f09 nfs: implement post-GAP transaction cleanup 
Close all prior transactions in the direction of the GAP, except the
file xfers. Those use their own logic described below.

After a GAP all normal transactions are closed. File transactions
are left open as they can handle GAPs in principle. However, the
GAP might have contained the closing of a file and therefore it
may remain active until the end of the flow.

This patch introduces a time based heuristic for these transactions.
After the GAP all file transactions are stamped with the current
timestamp. If 60 seconds later a file has seen no update, its marked
as closed.

This is meant to fix resource starvation issues observed in long
running SMB sessions where packet loss was causing GAPs. Due to the
similarity of the NFS and SMB parsers, this issue is fixed for NFS
as well in this patch.

Bug #3424.
Bug #3425.

Victor Julien 500e8da63a files: tracking flag update 
Improve flow file flags and file flags updates. Introduce a mask
that is set at start up to avoid lots of runtime checks.

Disable cocci flags check as it doesn't support the more dynamic
nature of the flag updates.

Timo Sigurdsson 1262ecbde0 init: Fix dropping privileges in nflog runmode 
Using the run-as configuration option with the nflog capture method
results in the following error during the startup of suricata:
[ERRCODE: SC_ERR_NFLOG_BIND(248)] - nflog_bind_pf() for AF_INET failed

This is because SCDropMainThreadCaps does not have any capabilities
defined for the nflog runmode (unlike other runmodes). Therefore, apply
the same capabilities to the nflog runmode that are already defined for
the nfqueue runmode. This has been confirmed to allow suricata start
and drop its privileges in the nflog runmode.

Fixes redmine issue #3265.

Victor Julien f8aed4ce2d threading: change local packet queue logic 
Previously each 'TmSlot' had it's own packet queue that was passed
to the registered SlotFunc as an argument. This was used mostly for
tunnel packets by the decoders and by defrag.

This patch removes that in favor of a single queue in the ThreadVars:
decode_pq. This is the non-locked version of the queue as this is
only a temporary store for handling packets within a thread.

This patch removes the PacketQueue pointer argument from the API.
The new queue can be accessed directly through the ThreadVars
pointer.

Works exactly like PacketQueue, just does not contain a mutex
and cond var, leading to much reduced memory size.

Victor Julien 569a5d985b threading: remove handler names to shink struct 
Shrink ThreadVars by removing the queue handler names that are only
used at shutdown. Since this is not performance critical, we can use
the id's to look up the queue handler.
