devel/librevisa: fix build with libc++ 19

As noted in the libc++ 19 release notes [1], std::char_traits<> is now
only provided for char, char8_t, char16_t, char32_t and wchar_t, and any
instantiation for other types will fail.

This causes devel/librevisa to fail to compile with clang 19 and libc++
19, resulting in errors similar to:

  /usr/include/c++/v1/string:820:42: error: implicit instantiation of undefined
template 'std::char_traits<unsigned short>'
    820 |   static_assert(is_same<_CharT, typename
traits_type::char_type>::value,
        |                                          ^
  usb/usb_resource_creator.cpp:73:20: note: in instantiation of template class
'std::basic_string<unsigned short>' requested here
     73 |         usb_string serial;
        |                    ^

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.

devel/librevisa: fix build error

On FreeBSD versions where libusb.h defines LIBUSB_CLASS_APPLICATION, the extra
definition from the Makefile prevents the port from building. Remove that extra
definition.

While here, add build dependency for pkg-config

Thank you Uffe for your past work on FreeBSD ports! Hope you'll find time
to contribute to FreeBSD in the future. Reset Uffe's ports maintainership.

By default libtool replaces -export-symbols <file> with -retain-symbols-file
<file> on ELF systems, but this doesn't really do what -export-symbols is
meant to do.  On GNU ELF systems it converts <file> to a simple version
script first and then uses -version-script instead of -retain-symbols-file.
Let USES=libtool patch libtool scripts to do this on all systems with GNU
ld(1).

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
