Mk/**tex.mk: Convert bsd.tex.mk to USES=tex

- Update all the consumers to use USES=tex
- USE_TEX=yes is the old way of writing USES=tex which has been removed
  and replaced in all ports
- Almost all of the USE_TEX features remains unchanged
- Some consumers had the same variables defined both in the mk
  infrastructure and also in the ports which have been removed from the
  ports as those are redundant.

In case any of the consumers are failing to build please make sure that
the nexessary USES=tex is there. Unlike previous USE_TEX=yes will no
longer load the required VARS for tex and related dependencies.

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.

One more small cleanup, forgotten yesterday.

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:*.

Cleanup plist

Finally add staging support.

While here, replace all the direct invocations of mktexlsr by
USE_TEX=texhash.

Convert p* to USES=zip

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

Explicitly use another name for the distfile.

Quite a while ago I started mirroring ltablex.zip because some CTAN mirrors
delivered a zip file with the same contents but a different checksum.

The package build cluster seems to have mirrored one of those "wrong"
versions, and every once in a while I get an email about package building
failures which are actually caused by that.

Work around the issue by renaming the ltablex.zip file I mirror to
ltablex-1.0.zip, which should hopefully make ftp-master re-fetch it.

Rectify USE_TEX to support both of teTeX and TeXLive.

TEX_DEFAULT:
	A knob to choose teTeX or TeXLive.  One can specify in /etc/make.conf.

USE_TEX:
	A knob for port developers.  Valid keywords are listed in
	bsd.tex.mk.

Remove *_DEPENDS from ports which depend on teTeX and add USE_TEX=tetex
instead to make migration to TeXLive easier.

Clean up the headers of the ports I maintain.

Unbreak by mirroring the tarball locally.

Some CTAN mirrors are returning a tarball with a different checksum. Work
around that by mirroring it locally.

Mark as broken: incorrect checksum.

Update checksum for the .zip file.

It looks like the checksum has changed for some reason. The file
contents are still the same, so I guess some repackaging was done
behind the scenes.

- Add print/latex-ltablex

ltablex modifies the tabularx environment to combine the features of the
tabularx package (auto-sized columns in a fixed width table) with those
of the longtable package (multi-page tables).
