Profpatsch 4a7f99d55d treewide: with stdenv.lib; in meta -> with lib;
Part of: https://github.com/NixOS/nixpkgs/issues/108938

meta = with stdenv.lib;

is a widely used pattern. We want to slowly remove
the `stdenv.lib` indirection and encourage people
to use `lib` directly. Thus let’s start with the meta
field.

This used a rewriting script to mostly automatically
replace all occurances of this pattern, and add the
`lib` argument to the package header if it doesn’t
exist yet.

The script in its current form is available at
https://cs.tvl.fyi/depot@2f807d7f141068d2d60676a89213eaa5353ca6e0/-/blob/users/Profpatsch/nixpkgs-rewriter/default.nix

'' XZ Utils is free general-purpose data compression software with high
compression ratio. XZ Utils were written for POSIX-like systems,
but also work on some not-so-POSIX systems. XZ Utils are the
successor to LZMA Utils.
The core of the XZ Utils compression code is based on LZMA SDK, but
it has been modified quite a lot to be suitable for XZ Utils. The
primary compression algorithm is currently LZMA2, which is used
inside the .xz container format. With typical files, XZ Utils
create 30 % smaller output than gzip and 15 % smaller output than
bzip2.
