Without it, building a document fails with the following error:
pdflatex failed
index.tex: File `pdflscape.sty' not found.
index.tex:47: Emergency stop.
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.
Changes the default fetcher in the Rust Platform to be the newer
`fetchCargoTarball`, and changes every application using the current default to
instead opt out.
This commit does not change any hashes or cause any rebuilds. Once integrated,
we will start deleting the opt-outs and recomputing hashes.
See #79975 for details.
