all: migrate homepages from http to https

pkglint -r --network --only "migrate"

As a side-effect of migrating the homepages, pkglint also fixed a few
indentations in unrelated lines. These and the new homepages have been
checked manually.

tbit
* add support for initial congestion window (ICW) inferences
* add new tests to check response to packets that could have been
  sent by a blind attacker
* add a TCP fast-open implementation, with both experimental
  and official option values
* add support for testing HTTPS and BGP.  drop FTP, DNS, and SMTP
* add sc_tbitblind driver that was used for IMC 2015 paper

trace
* add tx timestamp to hop records
* add dl option, to replace dlts option removed from scamper.
* process UDP responses, if a UDP probe method is used.

ping:
* add tcp-syn ping method.
* fix memory leak when payloads are specified in ping.

sc_ipiddump
* report IPID values from traceroute measurements, where available
* report the source IP address used to probe the destination

sc_filterpolicy:
* add a new scamper driver to test systems for congruent filtering policy
  http://www.caida.org/tools/measurement/scamper/man/sc_filterpolicy.1.pdf

scamper:
* update scamper maximum PPS to 10,000 (from 1000).  Its not 2002 anymore.
* bind to requested source port with UDP sockets.
* set SO_SNDBUF once, when a probe socket is created.
* remove dlts option which was only used by traceroute.
* drop divert socket from privsep, which was not used in scamper anywhere.
* shift socket creation glue from scamper_privsep.c to
  scamper_udp4.c, scamper_icmp6.c, etc.
* fix memory leak when receiving TCP responses in tracelb.
* do not use the global address cache in tracelb: use a local one.
* in qsort with 3-way partition, do not compare items against
  themselves.
* improve performance of warts_addr_t code
* use calloc instead of malloc() -> memset(0) on systems where calloc
  is available.
* do not use the global address cache in ping: most responses are
  either from the destination, or from the same IP address, so
  optimize for that.

Log message:
Update net/scamper to 20141211a. From maintainer in PR pkg/50138.

From https://rommie.caida.org/pipermail/scamper-announce/2015-August/000003.html

* provide the ability for scamper's control socket to bind to a
  specific address.  this allows external systems to contact and drive
  scamper processes.  a more secure solution will follow in a month or
  two.

* when converting the source port of a control socket client to a
  string, print it in host byte order rather than network byte order

* add a TBT (too-big-trick) option to ping, use it in sc_speedtrap.  a
  simple optimisation to send up to M packets to get N fragmented
  responses.

* if an input list to sc_speedtrap contains the same IP address twice,
  ignore the duplicate address, rather than crash later.

* use a quicksort with a 3-way partition.  will make scamper more
  efficient in many places.

* add sc_warts2csv for samknows

* fix sc_tracediff so that it doesn't crash if the two warts files
  being compared traceroute to different sets of addresses.  reported
  by Job Snijders.

Update scamper to 20141101  (PR pkg/49353)

20141101:
* fix passing file descriptors through sockets on NetBSD, so that
   scamper can actually work with privsep on NetBSD.
 * use arc4random on all platforms where available.  silences build on
   OpenBSD.
 * increase size of flags array for warts_dealias_data_t so that all
   of the prefixscan flags can fit.  pointed out by OpenBSD gcc.
 * silence build on NetBSD by casting parameter to isspace from char
   to int.
 * silence a couple spurious clang scan-build warnings with assert
   statements.

20141031:
In this Halloween release of scamper:

* work to make scamper compile and work on windows again.  use
  O_BINARY so that output warts files are not corrupted, set the timer
  granularity to 1ms, and handle polling/reading files outside of
  select().  Thanks to Philip Ramsey of Renesys for reporting these
  bugs and supplying the O_BINARY and timer fixes.  as part of trying
  to track down the output corruption I added malloc_zero everywhere,
  in vain, but kept it in scamper out of an abundance of caution.
* detangle scamper_fd_t from scamper_writebuf_t.
* in ping,
  - set a timeout after sending a PTB
  - print reply_ipid in json output for ipv6 echo replies, bump
    json version.
* update scamper -O options in the usage statement, and in the
  manual page

20140530:
* FreeBSD 10 onwards no longer byte swaps some fields in the quotation of
  a received ICMP error message.  chase this in scamper.
* Minor modifications to make scamper compile on Windows 7 using
  Visual Studio Express 2013 for Windows Desktop.
* print ping flags in sc_wartsdump and scamper's json output.
 email alias tied to this mailing list, please let me know.

20140404:
* allow scamper to be built in debug mode on FreeBSD after version 10.
* in scamper-ping, support a probe frequency smaller than once every
  second.  minimum is now once a millisecond.
* handle fragmented responses in linux and sunos correctly.
  this is important for IPv6 IP-ID based alias resolution techniques
  (e.g. speedtrap, ally, radargun) on those platforms.
* numerous bugfixes and improvements to sc_ally pair-wise alias
  resolution utility, the most important being that it will reliably
  complete now.

Update scamper to 20140122

from PR pkg/48546

scamper-dealias:
* many slight improvements to the implementation of the 'ally' alias
  resolution algorithm.
* add flag to prefixscan that says the alias was inferred using a common
  source address
* for json output, print flags, bump version.

scamper-ping:
* record ICMP parameter problem responses to ping.
* for json output, print tx time on probes.

sc_attach:
* add support for starting as a daemon.
* add support for specifying a command which will be used with each address
* document these options in manual page

sc_analysis_dump:
* update manual page to document unintuitive behaviour of -e option.

misc:
* getopt returns an int, not a char.  important on arm.  fixed in
  sc_wartscat, sc_speedtrap, and sc_analysis_dump,
* silence benign warnings from clang on MacOS and cppcheck.
