Fixes:		17bfc9d343da graphics/giflib: Update to 5.2.2

Pet portclippy and portfmt.

Approved by:    portmgr (blanket)

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.

Approved by:		portmgr (tcberner)

These ports were traditionally maintained by portmgr@ to ensure
that they receive an exp-run.

Let's entrust them to desktop@ with a stern "remember to exp-run".

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
cannot conflict with itself (due to logic in bsd.port.mk that
supresses the pattern match result in that case).

A few ports that set the conflicts variables depending on complex
conditions (e.g. port options), have been left unmodified, despite
probably containing outdated package names.

These changes should only affect the installation of locally built
ports, not the package building with poudriere. They should give an
early indication of the install conflict in cases where currently
the pkg command aborts an installation when it detects that an
existing file would be overwritten,

- Update MAINTAINER

There is a regression with the 5.1.2 update to giflib. This affects the
ability for applications to render gif images usually ocurring after the
first gif image is rendered. Upstream has been notified but has not yet
provided feedback.

giflib 5.1.2 was a security fix, so reverting is not reasonable.

"The removed check look redundant - I couldn't find a code path where
Private->RunningBits would exceed that limit after initialization.
(Currently Private->RunningBits is checked before it is initialized)."

In these cases the same trick as in the recent gettext update is used.
The ports install a symlink with the old library version.  When enough
of their dependent ports have had regular updates the remaining ones can
get a PORTREVISION bump and the links can be removed.

Also remove the devel/pcre dependency from USE_GNOME=glib20.  It causes
over 2200 packages to depend on devel/pcre while less than 200 actually
link with it.  The glib20 package still depends on devel/pcre so this
should not make a difference for ports with USE_GNOME=glib20.  Also,
libdata/pkgconfig/glib-2.0.pc lists pcre as a private library so
USE_GNOME=glib20 should not propagate it.
