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)

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.

This commit implements such a proposal and moves one of the WWW: entries
of each pkg-descr file into the respective port's Makefile. A heuristic
attempts to identify the most relevant URL in case there is more than
one WWW: entry in some pkg-descr file. URLs that are not moved into the
Makefile are prefixed with "See also:" instead of "WWW:" in the pkg-descr
files in order to preserve them.

There are 1256 ports that had no WWW: entries in pkg-descr files. These
ports will not be touched in this commit.

The portlint port has been adjusted to expect a WWW entry in each port
Makefile, and to flag any remaining "WWW:" lines in pkg-descr files as
deprecated.

Bump PORTREVISION on all ports where the build log contains -export-symbols.

audio/calf: This port builds a module that now exports only one function,
but it also builds a number of executables that link to this module and
expect to see other functions.  Because it's already a bit dodgy to link to
a module (libtool warns about this) let the module continue to export only
one function and instead build an ordinary library from the same source that
the executables can link to.  Fix a number of other issues in the same
Makefile.am and clean up the port Makefile.

japanese/scim-honoka: Tries to hide all symbols that start with an
underscore, but because this library is written in C++ all symbols start
with _Z so it ends up hiding everything.  Just don't hide anything at all
like the textproc/scim configure script does.

multimedia/schroedinger: Apply an upstream patch.

textproc/scim-input-pad: Same as japanese/scim-honoka.

- print/texlive-infra was renamed with print/texlive-tlmgr.
  Note that currently tlmgr(1) does not work because of
  lack of TLPDB.  This will be fixed.

- Lua libraries used in LuaTeX are separated into
  devel/tex-libtexlua and devel/texlibtexluajit.
  USE_TEX supports them via keywords "texlua" and "texluajit".

- libsynctex is currently installed by devel/tex-web2c.
  This will be separated into a single port.

- Add graphics/libpotrace and use installed libpotrace
  and libharfbuzz.
