Fix WWW in parent/child ports

Many of the WWW are overwritten later which means the wrong value
is used. This did not happen before where the children were either
 a) just using the pkg-descr from the parents
 b) or had their own separate pkg-descr with custom WWW

Use WWW?= in parents when the child's WWW is different.

Children that use the same WWW as the parent can just inherit it,
i.e., the child WWW can be removed.

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.

LAPACKE is a standard C language APIs for LAPACK, which introduces
the following features[1]:
- row-major and column-major matrix layout controlled by the first function
parameter;
- an implementation with working arrays (middle-level interface) as well as
without working arrays (high-level interface);
- input scalars passed by value;
- error code as a return value instead of the INFO parameter.
