net: Replace RMD160 checksums with BLAKE2s checksums

All checksums have been double-checked against existing RMD160 and
SHA512 hashes

net: Remove SHA1 hashes for distfiles

Add a patch to make this build on NetBSD again.
The hack to let lib/bsd-list.h substitute for <sys/queue.h> and
prevent the latter's processing fails miserably on NetBSD, because
on NetBSD, <net/if.h> requires the TAILQ_* macros which are not
defined in lib/bsd-list.h.
No PKGREVISION bump since this is a build fix only.

Update to version 2.35

ns-2.35 Released on Nov 4, 2011

* Provide fixes to the Tmix traffic generator, mainly to the one-way
  TCP implementation, but some changes to the Full-TCP version as well.
  Tmix with one-way TCP now performs comparably to Tmix with Full-TCP (albeit
  with longer running times and higher memory consumption). Includes
  contributions from David Hayes and DongXia Xu at Swinburne and relevant
  updates to the documentation and tests.
* Add Marcello Caleffi's Multi-path Dynamic Address RouTing (M-DART)
  protocol.
* Add Sidney Doria's Datagram Congestion Control Protocol (DCCP)
  implementation.
* Added the SYN_immediate_ack flag so that a DelAckSink agent will
  immediately ACK the first (SYN) packet sent by a TcpAgent. The patch contains
  changes to tcp-sink.{cc,h}, ns-default.tcl, and affected validation tests.
  All validation tests that use the syn_ in TcpAgent were set to
  SYN_immediate_ack=false except for the delayed test in test-suite-simple.tcl.
* During long simulations (30-60 minutes), ns would sometimes abort with the
  message "TcpAgent: negative RTO!". The problem was that TcpAgent::t_backoff_
  was overflowing and becoming negative, since it was doubled each time a
  backoff was triggered but maxrto_ prevented the time between doublings from
  growing beyond 60 seconds.
* This patch adds support for using one-way TcpAgents with the Tmix traffic
  generator, which previously only worked with FullTcp agents.
* Protocol for Unified Multicasting Through Announcements (PUMA)
  has been added.  PUMA is a distributed, receiver initiated, mesh based
  multicast routing protocol.
* A new SCTP patch from Nasif Ekiz and the University of Delaware team.
* added support for Non-Renegable Selective Acknowledgements (NR-SACK).
  To enable NR-SACKs, set useNonRenegSacks_ tcl bindable variable to 1 at
  both the data sender and the data receiver.
* Concurrent Multipath Transfer with Potentially Failed(CMT-PF) extension
  is default now. To use CMT, set useCmtPF tcl bindable variable to 0
  at the data sender.
* added new feature to support a limited size send buffer at the data
  receiver. Send buffer size can be specified by setting initialSwnd_ tcl
  bindable variable to desired value. By default, the variable is set to
  0 which means there is no constraint on the send buffer.
* congestion window (cwnd) updates are now done as specified at Section 7.2.1,
  7.2.2 and 7.2.3 of RFC4960. Also the number of missing reports to trigger
  fast retransmits is reduced to three as specified in RFC4960.
* bug fix. A bug discovered by Eduardo Ribeiro and Igor Gavriloff regarding
  to memory deallocation is fixed.
* new validation tests for NR-SACKs and limited send buffer size are added to
  the test suite.

ns-2.34 Released on June 17, 2009

* bugfix for 802.11Ext model (from Felix-Schmidt-Eisenlohr and team)
* mac/wirelessPhyExt:
* the power monitor class is responsible to continously track the sum of all
  reception power values of all frames arriving in parallel and of the noise
  floor. In the earlier implementation this cumulated power was only decreased
  in situations where no packet arrived. Otherwise, powers were always further
  summed up, leading to a wrong setting of this variable, and in consequence,
  a wrong behavior of physical packet reception calculations. Furthermore, the
  busy/idle signalling was not correct.
* Add AOMDV (On-demand Multipath Distance Vector Routing in Ad Hoc Networks)
  implementation from Marcello Caleffi
* Collection of bug fixes for 802.11Ext model (from Felix-Schmidt-Eisenlohr
  and team)
* mac/mac-802.11Ext:
* feedback to higher layers on transmission failure: xmit_failure_data_ is
  delivered when a unicast packet was finally not sent successfully- corrected
  NAV update: in case a NAV is active and a new NAV is advertised an updated
  only occurs in case the new NAV takes longer than the one already running
  - bugfix: corrected backoff handling when 0 backoff slots are selected:-
  bugfix: resolved memory leak on broadcast packet transmission- duplicate
  suppression support: reactivate the feature of duplicate detection on MAC
  layer as it was done in earlier versions
* code cleanup: removed TxTimer_t class
* bugfix: ACK frames: explicitly set basic modulation scheme
* mac/wirelessPhyExt:
* update of modulation table: new threshold values are taken for the different
  modulation schemes due to newer measurements
* bugfix: resched() instead of sched() in PowerMonitor::expire()
* code cleanup: removed friend class PowerTimer
* code cleanup: updated comment in recordPowerLevel()
* new implementation of PowerMonitor (PowerTimer class now obsolete)
* clarification of CSThresh variable (see below)
* mac/channel.cc: for wirelessPhyExt only: correct calculation of distCST,
  using PowerMonitorThresh_ as the critical borderline power and including
  antenna gains.
* tools/ranvar.cc: - bugfix: resolved memory leak in Erlang distribution
* Bug fixes for 802.11 infrastructure code, posted by Ilango Purushothaman.
* Patches for better memory management - use standard C++ lists to maintain AP
  and client tables, memory leaks fixed in AP scheduling queue
* Triggering of handoff in Ad-hoc mode - Bug reported by Mayur - Resolved by
  adding an if condition for checking the 802.11 mode.
* Note:  The following traces changed as a result of this, but were verified
  by Ilango: ./test-all-wireless-infra ./test-all-wireless-infra-mobility
  ./test-all-wireless-shadowing ./test-all-wireless-lan-aodv
  ./test-all-wireless-gridkeeper ./test-all-wireless-lan-newnode
* Import Tmix synthetic Internet traffic generation tool
* Disable string literal warning for gcc version > 4.2

Restore patches to configure script lost in an update some time back.
Does not fix the build, but advances it; now it's having some kind
of bizarre problem with <sys/queue.h>.

While here, add three small patches to silence a large pile of const
warnings that made it impossible to see anything else that was going
on.

Fix build with gcc 4.6

Fix build with gcc4.5

  - Improve Cygwin compatibility.
  - Bug fixes.

Add RMD160 digests.

Update ns to 2.27 and take maintainership.

Changes:
  - Changed list-based improvement to allow changing of
  channels. Previously only a single (static) list of nodes
  maintained. Now list of nodes maintained for each channel. Maybe
  extended for mobilenodes with multiple netif (talking to multiple
  channels) once the multiple netif support is in place.
  - Added validation test-suite for RNG in ns.
  - Added modified version of setdest from U. of Michigan. Also added an
  argument to setdest API that defines the version of setdest being
  used.
  - Change the name of dumbPolicy to nullPolicy for consistency with
  diffserv documentations (suggested by Alexander Sayenko
  <sayenko@cc.jyu.fi>)
  - Added list-based improvement to ns-2. Code contributed by Valerie
  Naoumuv (naoumov@inf.ethz.ch). The improvement involves maintaining
  a doubly-linked list to organise mobilenodes based on their
  X-coordinates. When sending a packet only those neighbor nodes are
  considered who are within a circle corresponding to the
  carrier-sense threshold energy level, below which a node cannot hear
  the packet. Improvement on original version where all nodes in
  topology is considered. considerable gain in run-time performance-
  goes down by about 4 to 20 times, depending on the size of the
  topology. The larger the topology and greater the no of nodes,
  greater the improvement seen with the list-based implementation. Pl
  see relevant papaer "simulation of large adhoc networks", appeared
  at MSWiM'03, san diego, USA for details.
  - Added script <color-event.pl> that takes event/color pairs and
  colors pkts in nam output files in order to highlight nam events.
  - Modified ns to build with tcl/tk8.4 and new otcl/tclcl (release
  pending).
  - Diffusion documentation added to ns-manual.
  - Diffusion changes made includes (1)Added tcl example scripts for 2
  phase-pull, push, 1 phase-pull and gear (with push and 2pp)
  scenarios.  For gear and other node-position dependent routing in
  diffusion, need to have a callback to update node positions. since
  the routing filter (like gear) is init'ed before node positions are
  assigned gear doesn't get the correct node positions, hence the
  callback is required. callback would also be reqd to support node
  movements in diffusion in future.  For now start gear filters (in
  tcl scripts) after node positions are assigned to nodes. This will
  go away once callbacks are implemented.  (2)Added fix suggested by
  Andreas Koepke <koepke@ee.tu-berlin.de> for overflow problem in
  lib/main/tools.cc
  - Added worm model to support simulations of Internet worm attacks.
  This model supports different abstract levels in simulations.  It
  simulates a detailed sub-network at packet level, and the rest of
  the Internet with an analytical model (SIR). It supports two worm
  scanning behaviors: random and local-preferred.
  - Added event tracing function for simple-mac and 802.11.  It was
  contributed by <a href="mailto:singal@nunki.usc.edu">Sushmita</a> to
  support wireless animations.
  - Added directory for nam animations under ns/tcl/edu. Each
  subdirecotry contains on animation, including short description,
  simulation script, trace file, and nam trace.  These animations are
  ready to use in classroom. The current three animations are
  contributed by Sushmita <singal@nunki.usc.edu> as the outcome of her
  directed research project.
  - Integrated support for infrastructure mode in 802.11 MAC. The code
  was was written by Mike Moreton
  - Fixed bug (reported by Fred Stann) in diffusion3 that caused
  overflow while reading time ( > 2147 sec).
  - New module Delayer for introducing delay variation and channel
  allocation delay.  This is useful for modeling the effects of
  wireless links.  Validation tests in "./test-all-links".  Code
  contributed by Andrei Gurtov.
  - Ported SCTP into ns-2. It was actually ported into ns-2.26 by
  Armando L. Caro Jr. <acaro@@cis.udel.edu> and his group at PEL, Univ
  of delaware. The implementation includes a test-suite-sctp and doc
  for sctp (see chapter on SCTP in ns-manual).
  - Added APIs for diffusion filters to node-config command. See
  tcl/ex/diffusion3 for examples. Also changed UIDs in common pkt
  hdr. It now reflects pkt_num_ as in diffusion message hdr.
  - Adding ts_resetRTO_ to TCP to control whether or not a
  timestamp-enabled sender unbacks a backed-off RTO after making a
  valid RTT measurement from an acknowledged, retransmitted packet.
  Validation tests are in "./test-all-tcpOptions" in "tcl/test":
  "./test-all-tcpOptions timeouts_sack2" (with ts_resetRTO_ true)
  "./test-all-tcpOptions timeouts_sack3" (with ts_resetRTO_ false).
  The suggestion and initial code for this change are from Andrei
  Gurtov.  Also adding exitFastRetrans_ to TCP, to fix a problem
  with clean exits from Fast Recovery.  Set to false for the old buggy
  behavior, or set to true for the new good behavior.  The default is
  true.  "./test-all-tcpOptions timeouts_reno_noexitFR" shows the old
  behavior, and: "./test-all-tcpOptions timeouts_reno" shows the fixed
  new behavior.  The problem was that data was sent in response to dup
  acks even after Fast Recovery was over.  From a bug report by Andrei
  Gurtov.
  - Improved portability for C++ namespaces
  (required for gcc-3.2 where the standard C++ libraries like iostream
  are in namespace stl only).
  - Added trace support for smac. The "mactype" info stored in
  simulator is used to trace data as well as mac pkts (smac or
  802.11).
  - Ported diffusion3.2.0 into ns. A lot of changes: all applications
  re-categorized under gear, ping and rmst. Filters have a separate
  dir. gradient now replaced with one-and two-phase-pull-filter under
  filter_core.
  - Changed the defaults for Agent/TCP/Newreno's newreno_changes1_ and
  partial_window_deflation_ to "1", to reflect RFC 2582.
  - Adding avoidReordering_ to DelayLink, set to true to avoid
  reordering when changing link bandwidth or delay.  The code was
  contributed by Andrei Gurtov, and the validation test is in
  ./test-all-links in the directory tcl/test.  The default is for
  avoidReordering_ to be false, for no change in past behavior.
