benchmarks/spp: Sanitize MANPREFIX

Approved by:	portmgr (blanket)

Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

benchmarks: remove 'Created by' lines

benchmarks/spp: Update v0.4 -> v0.4.2

Version 0.4.2
- Fixed globals in master and slave (had a few non-static globals with same
  name)

Version 0.4.1
- Fixed bug that included random bytes in the hash input used to generate the
  packet id in cases where the captured bytes did not include the TCP option
  bytes or the first 12 bytes for TCP/UDP payload. Now for the TCP options, the
  UDP/TCP payloads and data for non UDP/TCP, the capture length (snap size) will
  limit the hash input.

Changes:	https://bitbucket.org/caia-swin/spp/src/v0.4.2/Changelog.txt
PR:		251002

Assume maintainership of benchmarks/spp and update to v0.4 which addresses:

  - Added pointer to reports/130730A/CAIA-TR-130730A.pdf">http://caia.swin.edu.au/reports/130730A/CAIA-TR-130730A.pdf
  - Fixed threading bug that causes segfault with newer pthread lib on Linux
  - Directory bin is now created during make (if it doesn't exists)
  - Added support for DLT_PPP frames in pcap files
  - Create fake "ip_len" if missing (observed in some TSO'ed frames)
  - Noted that IP.ID is no longer useful for disambiguating packets (RFC 6864)
  - Added "-# 8192" to hash across first 12 bytes of TCP payload
  - Added "-# 16384" to hash across all TCP Option bytes
  - Added -O option to print 'fake' (uncorrected) OWD in each direction
  - Various documentation tweaks (README and man page source)
  - Change default hash function for packet id generation to crc64 and added
  - Added -H option to select hash function (crc32 and crc64)
  - Added autotuning of delta_t_max based on actual observed clock offset
    (disabled with -T option)

SPP provides frequently updated RTT estimates using IP traffic already
present in the network. SPP estimates the RTT between two measurement
points without requiring precise time synchronisation between each
point. SPP accurately estimates the RTT experienced by any application's
traffic without needing modifications to the application itself
or the routers along the path.
