The old cygwin support used -pc-windows-cygnus as the config. This is
supported by LLVM, but not by GNU. This will change it to -pc-cygwin,
which is more generally supported.
Because the kernel is now 'cygwin' rather than 'windows', isWindows will
return false. There are lots of different reasons isWindows is used in
nixpkgs, but in my experience they often have to do with posix
compatibility and don't apply to cygwin.

It was voluntarily retired. Still, it's used in some projects.
Specifically, openvswitch ships some files under lib/sflow*[ch] under
this license.
This license will be added to both openvswitch and ovn packages (the
latter embeds openvswitch libraries, including sflow).
Allows marking an option as invisible, without excluding its sub-options.
In practice, this is similar to `visible = true; internal = true;`,
however it is more explicit and less reliant on implementation details.
renamed `mac` to `octets` in hextets combining step for better var
naming; rephrased error message to provide a hint of expected format;
replaced `Arguments` with `Inputs` in docstring; added more test cases
for invalid hex digits; added comments in hextets combining step;
A Cross Index, short for Cross Platform Pair Index, is the essential
shape of a splice, without the invoking the more mind bending concept
of adding variations of for these 6 pairings to an existing thing so
that it can be switched out for something else.
So the purpose of a Cross Index is to contain the result of `f`\
(which may be reified in code, or just an abstract concept):
- f "build" "build"
- f "build" "host"
- ...
Splicing on the other hand refers not just to these six variants, but
to the idea of tacking them onto one of the variants. (hostTarget,
I believe)
Cross Indexes are a necessity for making cross compilation work, but
splicing is more than necessary.
At the scale of Nixpkgs, actively maintaining a package is only possible
with integration into CI. To be able to be pinged for review requests,
the maintainer must have a GitHub handle, which:
- Leads to an invitation to the NixOS org, which comes with additional
privileges.
- Allows to request the maintainer for review as a member of this org.
- Automatically requests the maintainer for review in CI.
Currently, the GitHub handle is not strictly enforced. This leads to
some new maintainers accidentally forgetting to set these. We can avoid
these mistakes and enforce them via CI.
The GPL-2.0-with-classpath-exception is deprecated in spdx and the exception Classpath-exception-2.0 should be used instead.
Other Classpath license hace also benn replaced with it.
Add `identifiers` attr to `meta` attribute with following attrs:
* `cpe` with the full CPE string when available
* `possibleCPEs` with the list of potential CPEs when not all
information is provided
* `cpeParts` with the destructured CPE string, allowing to override it
whenever needed
* `v1` attribute set with `cpe` and `cpeParts` from above and a
guarantee of a backwards-compatible interface

relevant changes:
- font is now in $out/share/fonts/X11 instead of $out/lib/X11/fonts
i have no idea why fonts would be in lib, so lets see if this breaks
anything
- font is now under the license adobeUtopia (recognised by SPDX) instead
of unfreeRedistributable
Previously, any subsequent change to a derivation after
an `addMetaAttrs` call would cause said attribute(s) to
be unconditionally reset back to their previous value(s):
nix-repl> ((oldPkgs.lib.lowPrio oldPkgs.hello).overrideAttrs {a = 1;}).meta.priority
error:
… while evaluating the attribute 'meta.priority'
at /nix/store/nxdiklm6dnf9pma1zg7srls2nzrykrjf-nixos/nixos/pkgs/stdenv/generic/make-derivation.nix:846:17:
845| inherit passthru overrideAttrs;
846| inherit meta;

847| }
error: attribute 'priority' missing
at «string»:1:67:
1| ((oldPkgs.lib.lowPrio oldPkgs.hello).overrideAttrs {a = 1;}).meta.priority

This change makes it so that this does not happen (unless, of
course, a subsequent override does affect those values):
nix-repl> ((newPkgs.lib.lowPrio oldPkgs.hello).overrideAttrs {a = 1;}).meta.priority

Fixes#323624.
