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

longDescription = ''
The mcelog daemon accounts memory and some other errors in various ways
on modern x86 Linux systems. The daemon can be queried and/or execute
triggers when configurable error thresholds are exceeded. This is used to
implement a range of automatic predictive failure analysis algorithms,
including bad page offlining and automatic cache error handling. All
errors are logged to /var/log/mcelog or syslog or the journal.
