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.

One more small cleanup, forgotten yesterday.

Remove # $FreeBSD$ from Makefiles.

Install texinfo files (GNU info) into ${PREFIX}/share/info

After a discussion on the mailing list on moving manpages to
${PREFIX}/share/man for consistency with base where it is
installed in usr/share/man, it appeared the same should happen
to GNU info files which were installed under share in base and
not in ports.

Now texinfo is not in base on any of the supported version of FreeBSD
it is possible to proceed to this move and it is easier to do than
the manpage change.

Other benefit than consistency are less patching: all build tools but
cmake are expecting info files to be under share/info and cmake (patched here)
was having an exception for BSD so the patch makes FreeBSD case less
specific for them

Update TeXLive to TL2015.

- print/texlive-infra was renamed with print/texlive-tlmgr.
  Note that currently tlmgr(1) does not work because of
  lack of TLPDB.  This will be fixed.

- Lua libraries used in LuaTeX are separated into
  devel/tex-libtexlua and devel/texlibtexluajit.
  USE_TEX supports them via keywords "texlua" and "texluajit".

- libsynctex is currently installed by devel/tex-web2c.
  This will be separated into a single port.

- Add graphics/libpotrace and use installed libpotrace
  and libharfbuzz.

- Add pTeX support to xdvik.  This improvement is imported from
  the latest j1.42 patchset by adjusting it to the 22.87 code base.

- Move files in TEXMFDISTDIR/xdvi to TEXMFDISTDIR/dvips/xdvi.

Cleanup plist

Update TeXLive to 2014.

- Note that full support of configuration tools such as tlmgr and texconfig
  is not ready yet.

- Most of dviware now supports libpaper to choose the default papersize.
  Use paperconfig(8) utility or print/papersize-default-* packages.

- Some quite old macros of the age of latex209 have been removed, and
  there are user-visible/invisible incompatibilities.  Please send a report
  to freebsd-tex@FreeBSD.org or file a PR if you have trouble.

Support stage for texlive, given it is impossible to rebuild the fmt files into
the stage then they are now rebuild in post-installation, like it is done in
other package system

- Switch print/libpaper to USES=libtool, drop .la files
- Bump dependent ports as .so version has changed

- Fix duplicated pkg-plist entries.
- Split off documentation to print/texlive-docs from print/texlive-texmf.
  The document part was 1.3GB (30k files).  Now the size of texlive-texmf
  package is 557MB (this was 1.5GB before the split).
- do-texhash, do-fmtutil, do-updmap targets now run after post-install.

Add USE_TEX=texlive for TeXLive-specific ports.

Split off print/tex-dvipsk from print/texlive-base.  libpaper support
will be added later.

Copy print/tex-dvipsk from print/dvipsk-tetex.  Changes will follow.
