This function returns the individual components
of the timeval in output pointers making it suitable
for use over Rust FFI.

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.

Set the livedev on reassembled packets to that of the parent
packet. Fixes issues with multidetect, specifically a segfault
as reported in issue 3380.

Bug OISF#3380.

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 OISF#3265.

Close all prior transactions in the direction of the GAP, except the
file xfers. Those use their own logic described below.

similarity of the NFS and SMB parsers, this issue is fixed for NFS
as well in this patch.

Fix function CheckOverlap bug.

When a TCP DNS flow would start with a GAP on the TS side, the successful
protocol detection on the TC side would trigger 'opposing side' reassembly
and app-layer processing. In this case the stream flags would indicate the
wrong direction and the wrong parser would be called.

This commit places restrictions on the length of the file name specified
in attachments (`name=` or `filename=`) to `NAME_MAX`. Names exceeding
these limits will be truncated and processing will continue with the
truncated name.
