This helps kpathsea to find texmf.cnf in some cases. For example,
dvipng was trying to look for it in
/nix/store/<hash>-texlive-dvipng.bin-2019/ instead of
/nix/store/<hash>-texlive-combined-full-2019/.
Announced in [1], versioned tarballs allow to make sure that a
specific version is fetched. This does not guarantee that all previous
versions are retained on the main mirrors.
Logically, we would want to first try to download versioned tarballs
from any mirror and only then try the unversioned ones. But right now
we only have two mirrors and only some of the tarballs are versioned
in texlive-2019, so the order is changed to not hammer the weak
tug.org mirror.

The biber package is now at 2.14, but TextBibTeX is still required.
Few changes were needed for newly introduced scripts-extra path. This
broke some of our old tricks which were relying on having writable
script directories. The changes to the script locations made buildEnv
create symlinks to the script directories instead of directories of
symlinks to scripts. The changes to texlinks.sh and texlive/TeXLive
perl path were made because of this.
The shell script doesn't work very well in non-GNU environments like
darwin. This provides an implementation that uses just a single GNU tool
- gawk, thus reduces number of points of failure.
The `bash` pragma gives syntax highlighting on the file, and removing the
prompts allows a user to just copy-paste the entire block into the terminal to
run the update.
biber: 2.12 -> 2.13
Vendored potrace was moved from libs/potrace to
texk/dvisvgm/dvisvgm-src/libs/potrace. Unfortunately, it is not trivial
to remove it from there, so for now dvisvgm seems to be using its
vendored dependencies.
There ver very many conflicts, basically all due to
name -> pname+version. Fortunately, almost everything was auto-resolved
by kdiff3, and for now I just fixed up a couple evaluation problems,
as verified by the tarball job. There might be some fallback to these
conflicts, but I believe it should be minimal.

texlive attribute was accidentally added in attrset wrapped with
stdenv.lib.optionalAttrs (!stdenv.isDarwin)
