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.

Remove # $FreeBSD$ from Makefiles.

Remove libiconv.so.3 compatibility link that was added in r374303 to
prevent massive PORTREVISION bumps.  Bump dependent ports that have not
been bumped since.

converters/libiconv:
- Remove const qualifier from iconv(3) to match POSIX:
  http://pubs.opengroup.org/onlinepubs/9699919799/functions/iconv.html
- Patch iconv.h to expose more GNU extensions when LIBICONV_PLUG is
  defined because the base system iconv supports these extensions too.

Add/remove patches to/from ports to call iconv with non-const arguments.

This breaks some ports on FreeBSD 10 because base system iconv.h still has
the const qualifier.  Fix this by letting USES=iconv add a build dependency
on converters/libiconv so ports can use its iconv.h (with LIBICONV_PLUG
defined) instead of the base system iconv.h.

This exposed some ports that link with libiconv when it is available instead
of using libc iconv.  In these cases one of the following changes has been

Support staging

- Reassign lioux' ports to the heap

Add NO_STAGE all over the place in preparation for the staging support (cat:

- Make ports use the libc provided iconv implementation on 10-CURRENT

- Fix a bunch of ports to properly work after this
- Mark converters/libiconv as IGNORE for systems with iconv in libc

Fix typos in COMMENT

Approved by:	portmgr@ (implicit)

The vast majority of pkg-descr files had the following format when they
had both lines:

Author: ...
WWW: ....

So standardize on that, and move them to the end of the file when necessary.

Also fix some more whitespace, and remove more "signature tags" of varying
forms, like -- name, etc.

s/AUTHOR/Author/

A few other various formatting issues

- remove MD5

Add LICENSE* information

Update to 1.19

o Add X-DSPAM-* to the strip headers list side by side with X-CRM114-*
o Bump PORTREVISION

Update to 1.18.20070320

Add SHA256 checksum

o Improve previous fix for building on OSVERSION < 500000: simple
  patch instead of USE_GCC=3.4+
o Bump PORTREVISION due to dependency change

Fix build: USE_GCC=3.4+ on ${OSVERSION} < 500000 (c++ template
issues)
