net/norm: fix build with clang 16

Since clang 16 (and gcc 11) the default C++ standard is now gnu++17.
Because net/norm's build system does not explicitly set the C++
standard, this leads to several errors:

  ../src/common/normEncoderRS8.cpp:264:5: error: ISO C++17 does not allow
'register' storage class specifier [-Wregister]
      USE_GF_MULC ;
      ^
  ../src/common/normEncoderRS8.cpp:136:21: note: expanded from macro
'USE_GF_MULC'
  #define USE_GF_MULC register gf * __gf_mulc_
                      ^
  ../src/common/normEncoderRS8.cpp:265:5: error: ISO C++17 does not allow
'register' storage class specifier [-Wregister]
      register gf* dst = dst1;
      ^~~~~~~~~
  ../src/common/normEncoderRS8.cpp:266:5: error: ISO C++17 does not allow
'register' storage class specifier [-Wregister]
      register gf* src = src1 ;
      ^~~~~~~~~

Add USE_CXXSTD=gnu++98 to compile for C++98 with GNU extensions instead,
as net/norm does not seem to use any C++11 or later constructs.

net/norm: use upstream divert(4) patches to avoid warning on CURRENT

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.

Approved by:		portmgr (tcberner)

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.

One more small cleanup, forgotten yesterday.

Remove # $FreeBSD$ from Makefiles.
