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.

Support LIBS like LDFLAGS.

- Add LIBS="${LIBS}" to MAKE_ENV and CONFIGURE_ENV.
- Add an option helper for LIBS.
- Adjust all ports that already use LIBS.  Also remove references to
  PTHREAD_CFLAGS and PTHREAD_LIBS while here.
- Some ports did not support having a LIBS environment variable and
  required additional patches.

Somewhat simplified a linker command line looks like:

${CC} ${src_LDFLAGS} ${LDFLAGS} ${src_LIBS} ${LIBS}

where src_LDFLAGS and src_LIBS are controlled by upstream and LDFLAGS and
LIBS can be controlled by us.  If possible -L and -l flags need to be

- Stage support
- Use new LIB_DEPENDS format

Eradicate USE_GNOME=pkgconfig from graphics
While here:
- trim headers
- convert:
  * USE_GNOME=gnomehack -> USES=pathfix
  * USE_GMAKE=yes -> USES=gmake
  * USE_PERL5 -> USES=perl5

- update png to 1.5.10

- Add LDFLAGS to CONFIGURE_ENV and MAKE_ENV (as it was done with LDFLAGS)
- Fix all ports that add {CPP,LD}FLAGS to *_ENV to modify flags instead

Pngnq is a tool for quantizing PNG images in RGBA format.

Pngnq is an adaptation by Stuart Coyle of Greg Roelf's pnqquant using
Anthony Dekker's neuquant algorithm.

The neuquant algorithm uses a neural network to optimise the color map
selection. This is fast and quite accurate, giving good results on many
types of images.
