We now pass in a Info struct that contains:
- the path name (as before)
- the rotation interval
- the log_rotate_base_time in seconds
- a table of key/value pairs with further configuration options.
To fill the table, log filters have a new field "config: table[string]
of strings". This gives a way to pass arbitrary values from
script-land to writers. Interpretation is left up to the writer.
Also splits calc_next_rotate() into two functions, one of which is
thread-safe and can be used with the log_rotate_base_time value from
DoInit().
Includes also updates to the None writer:
- It gets its own script writers/none.bro.
- New bool option LogNone::debug to enable debug output. It then
prints out all the values passed to DoInit(). That's used by a
btest test to ensure the new DoInit() values are right.
- Fixed a bug that prevented Bro from terminating..
(scripts.base.frameworks.logging.rotate-custom currently fails.
Haven't yet investigated why.)

SOCKS DPD fixes.
Fix a bug in the SOCKS analyzer.
SOCKS and tunnel test updates.
Updates for the SOCKS analyzer.
Very small updates to the tunnels framework.
- Make the uid field optional since it's conceptually incorrect
for proxies being treated as tunnels to have it.
- Reordered two fields in the log.
- Reduced the default tunnel expiration interface to something more
reasonable (1 hour).

Conflicts:
src/event.bif
Teredo bubble packets (IPv6 w/ No Next Header and zero Payload Length)
with data extending past the inner IPv6 header (the outer IPv4 header's
Total Length and UDP header's Length indicate this) now only raises
a "Teredo_payload_len_mismatch" weird instead of causing a
ProtocolViolation().
This also fixes a crash in NetSessions::ParseIPPacket() that occurred
when the packet length didn't match the payload length field.
* origin/topic/jsiwek/tunnels-merge:
Remove &synchronized from Tunnel::active table.
Refactor of interal tunnel analysis code.
Add state management of NetSessions's IP tunnel map.
Add "encap_hdr_size" option back in.
Script-layer tunnel interface cleanup.
- Pulled more common code into NetSessions::DoNextInnerPacket()
and made the pcap header it makes internally use network_time
- Remove Encapsulation class ctor from pointer
- Rename Encapsulation class to EncapsulationStack
The "tunnel_port" and "parse_udp_tunnels" options are still gone
as those did not work entirely (e.g. IPv6 support and misnaming
of tunnel_port/udp_tunnel_port).
- Clarify "tunnel_changed" event documentation.
- Make expiration of "Tunnel::active" elements configuration via
"Tunnel::expiration_interval".
- Remove redundant registration of a connection's tunnels in
tunnel/main.bro's "tunnel_changed" handler.
- Rename "parents" field of "Conn::Info" to "tunnel_parents"
to give more context.
* origin/fastpath:
Remove an old, unused diff canonifier.
Improve an error message in ICMP analyzer.
Fix a warning message
Fix many errors in the event documentation
Fixed broken links, broken reST formatting, added missing event
parameters to the documentation, removed documentation of event
parameters that don't exist, corrected spelling errors, fixed some
summary lines (i.e., the first line in each event description) that
were truncated in the HTML, and reformatted some lines to fit
within 80 columns (much easier to read the docs when using a
text editor to view the source files).
