texlive: update to 2020

General:
* The \input primitive in all TeX engines, including tex, now also accepts a
  group-delimited filename argument, as a system-dependent extension. The usage
  with a standard space/token-delimited filename is completely unchanged. The
  group-delimited argument was previously implemented in LuaTeX; now it is available
  in all engines. ASCII double quote characters (") are removed from the \ 
filename,
  but it is otherwise left unchanged after tokenization. This does not currently
  affect LaTeX’s \input command, as that is a macro redefinition of the standard
  \input primitive.
* New option –cnf-line for kpsewhich, tex, mf, and all other engines, to support
  arbitrary configuration settings on the command line.
* The addition of various primitives to various engines in this and previous years
  is intended to result in a common set of functionality available across
  all engines.

epTeX, eupTeX: New primitives \Uchar, \Ucharcat, \current(x)spacingmode, \ifincsname;
 revise \fontchar?? and \iffontchar. For eupTeX only: \currentcjktoken.

LuaTeX: Integration with HarfBuzz library, available as new engines luahbtex
 (used for lualatex) and luajithbtex. New primitives: \eTeXgluestretchorder,
 \eTeXglueshrinkorder.

pdfTeX: New primitive \pdfmajorversion; this merely changes the version number
 in the PDF output; it has no effect on any PDF content. \pdfximage and similar
 now search for image files in the same way as \openin.

pTeX: New primitives \ifjfont, \iftfont. Also in epTeX, upTeX, eupTeX.

XeTeX: Fixes for \Umathchardef, \XeTeXinterchartoks, \pdfsavepos.

Dvips: Output encodings for bitmap fonts, for better copy/paste capabilities.

Import tex-pstools-1.68 as graphics/tex-pstools.

Produce Encapsulated PostScript Files (EPS/EPSF) from a one-
page PostScript document, or any PostScript document. A correct
Bounding Box is calculated for the EPS files and some
PostScript command sequences that can produce errorneous
results on printers are filtered. The input is cropped to
include just the image contained in the PostScript file. The
EPS files can then be included into TeX documents. Other
programs like ps2epsi (a script distributed with ghostscript)
don't always calculate the correct bounding box (because the
values are put on the PostScript stack which may get corrupted
by bad PostScript code) or they round it off, resulting in
clipping the image. Therefore ps2eps uses a resolution of 144
dpi to get the correct bounding box.
