japanese/zinnia: fix build with clang 16

Since clang 16 (and gcc 11) the default C++ standard is now gnu++17.
Because japanese/zinnia's build infrastructure does not explicitly set
its C++ standard, this leads to an error:

  svm.cpp:50:10: error: no member named 'random_shuffle' in namespace 'std'
      std::random_shuffle(index.begin(), index.begin() + active_size);
      ~~~~~^

This is because std::random_shuffle has been removed from C++17. An
suitable replacement is std::shuffle, using a std::random_device in
combination with std::mt19937 as the random number engine.

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.

japanese: remove 'Created by' lines

Cleanup plist

- Switch to USES=libtool, drop .la files
- Add LICENSE_FILE

Approved by:	portmgr blanket

- Trim Makefile header; remove LICENSE_FILE for a well-known license
- Set LICENSE for more specific, albeit more ugly, BSD3CLAUSE
- Remove USE_GMAKE: seems to build fine with BSD default make(1)
- Stagify, set OPTIONS_DEFINE (for DOCS), convert to use PORTDOCS

Add NO_STAGE all over the place in preparation for the staging support (cat:
japanese)

Fix typos in COMMENT

Approved by:	portmgr@ (implicit)

- Remove WITH_FBSD10_FIX, is no longer needed

- Fix build on FreeBSD 10

Zinnia is a simple, customizable and portable online hand recognition system
based on Support Vector Machines. Zinnia simply receives user pen strokes as a
sequence of coordinate data and outputs n-best characters sorted by SVM
confidence. To keep portability, Zinnia doesn't have any rendering
functionality. In addition to recognition, Zinnia provides training module that
allows us to create any hand-written recognition systems with low-cost.
