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.

Fix CONFLICTS entries of multiple ports

There have been lots of missing CONFLICTS_INSTALL entries, either
because conflicting ports were added without updating existing ports,
due to name changes of generated packages, due to mis-understanding
the format and semantics of the conflicts entries, or just due to
typoes in package names.

This patch is the result of a comparison of all files contained in
the official packages with each other. This comparison was based on
packages built with default options and may therefore have missed
further conflicts with optionally installed files.

Where possible, version numbers in conflicts entries have been
generalized, some times taking advantage of the fact that a port

textproc/irstlm: unbreak with GCC >= 6

GCC defaults to C++14 since 6.0 which no longer converts istream to

MASTER_SITES cleanup.

- Replace ${MASTER_SITE_FOO} with FOO.
- Merge MASTER_SITE_SUBDIR into MASTER_SITES when possible. (This means 99.9%

- Remove occurrences of MASTER_SITE_LOCAL when no subdirectory was present and
  no hint of what it should be was present.
- Fix some logic.
- And generally, make things more simple and easy to understand.

While there, add magic values to the FESTIVAL, GENTOO, GIMP, GNUPG, QT and
SAMBA macros.

Also, replace some EXTRACT_SUFX occurences with USES=tar:*.
