So far, the output binary has been just "validate", which is quite a
very generic name and doesn't match the package name.
Even though I highly doubt that this program will ever be used outside
of NixOS modules, it's nevertheless less confusing to have a consistent
naming.

The only reason why I was using _GNU_SOURCE was because of vasprintf(),
so getting rid of that extension should make the source way more
portable.
When using vsnprintf() with a null pointer for the output buffer and a
size of 0, I wasn't quite sure whether this would be undefined
behaviour, so I looked it up in the C11 standard.
In section 7.21.6.5, it explicitly mentions this case, so we're lucky:
If n is zero, nothing is written, and s may be a null pointer.
Additionally, section 7.21.6.12 writes the following about vsnprintf():
The vsnprintf function does not invoke the va_end macro.
So to be sure to avoid undefined behaviour I subsequently added the
corresponding va_end() calls.
With this, the platforms attribute is now "unix", because the program
should now even run on OS X, even though it usually wouldn't be needed.

I initially didn't use $CC because I thought this would be GCC specific,
but it turns out that Clang actually accepts -std=gnu11.
So using $CC here might not work on compilers other than Clang or GCC,
but at the moment those are the compilers we typically use in nixpkgs,
so even if we'd use some other compiler it *might* even work there.
I've tested this by compiling against clangStdenv with both $CC and
clang hardcoded and it works.
This was reported by @dkudriavtsev on IRC.

1.2 only allows running in the foreground if debug mode is enabled which
generates lots of noise for journald.
The changes from the most recent release is only a few minor fixes plus support
for running in the foreground with the `-f` flag.
A recent upgrade of cargo-vendor changed its output slightly, which
broke all cargoSha256 hashes in nixpkgs.
See https://github.com/NixOS/nixpkgs/issues/60668 for more information.
Since then, a few hashes have been fixed in master by hand, but there
were a lot still to do, so I did all of the ones left over with some
scripts I wrote.
The one hash I wasn’t able to update was habitat's, because it’s
currently broken and the build doesn’t get far enough to produce a
hash anyway.
This stops arandr from crashing if it tries to open a dialog box.
Note: the hook doesn't play nicely with gobject-introspection unless
strictDeps = false. See NixOS#56943.
