converters/iconv-rfc1345: add license

There is no indication of a license intended by the author, but
since this is an extension of the converters/iconv port which is
distributed under a 3-clause BSD license, add it to this port, too.

While here use @preunexec instead of the deprecated @unexec in
pkg-plist.

Approved by:	bland (maintainer)

Remove # $FreeBSD$ from Makefiles.

Remove ${PORTSDIR}/ from dependencies, Mk and categories a, b, and c.

MASTER_SITES cleanup.

- Replace ${MASTER_SITE_FOO} with FOO.
- Merge MASTER_SITE_SUBDIR into MASTER_SITES when possible. (This means 99.9%
  of the time.)
- 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:*.

SIZEify (maintainer timeout)

De-pkg-comment.

Iconv cleanup, stage 1a: remove `g' prefix from binaries, headers, libraries and
manpages installed by libiconv (aka GNU iconv) and add similar `b'-prefixes
into components installed by iconv (aka BSD iconv). The reason why we do this
is because unfortunately BSD iconv become abadonware (author doesn't maintain
it anymore), while number of ports that need functional iconv library grows
very fast, thus creating significant overhead due to patches needed to make
ports working with prefixed GNU iconv. For compatibility reasons create
symlinks in GNU iconv, so that all ports that expect GNU iconv to have `g'
prefix should work unmodified until all those `g'-hacks are wiped out.
