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.

math: remove 'Created by' lines

For ports maintained by ports@FreeBSD.org, remove names and/or
e-mail addresses from the pkg-descr file that could reasonably
be mistaken for maintainer contact information in order to avoid
confusion on the part of users looking for support. As a pleasant
side effect this also avoids confusion and/or frustration for people
who are no longer maintaining those ports.

Deal with the libgmp dependency properly:
- Don't depend on math/libgmp-freebsd on FreeBSD <= 500023, use the base
  libgmp instead. On FreeBSD > 500023 depend on math/libgmp4, as
  math/libgmp-freebsd doesn't build on all architectures.
- Don't add PREFIX/include and PREFIX/lib to the search paths by default,
  so on FreeBSD 4 the base libgmp is used. This protects from using one of
  the libgmp ports if installed without registering a dependency on it.
- Keep from auto-detecting libgmp when WITHOUT_GMP is defined by specifying
  the arithmetic to use.
  Note: When using auto-detection and libgmp can't be found ndiff normally
  would check for extended precision arithmetic first and succeed with it.
  But using extended precision arithmetic causes the test suite to fail
  (i.e. lots of differences) on all architectures expect sparc64. Therefore
  specify double precision arithmetic for all other architectures when built
  with WITHOUT_GMP.

Add a port of ndiff:

ndiff is a utility for comparing putatively similar files, ignoring small
numeric differences.  The utility is written by Nelson H.  F. Beebe and
covered by the GNU General Public License (GPL), version 2.  It may be
built with arbitrary precision support (more powerful) or using built-in
floating point precision, see Makefile.

Assessing the consistency of a numerical program run in multiple
environments (operating systems, architectures, or compilers) can be a
difficult task for a human, as small differences in numerical output values
are expected.  File differencing utilites, such as diff(1), will generally
produce voluminous output, often longer than the original files.

ndiff solves this problem. Taking two two text files expected to be
