eldritch horrors 112fd6c971 rewrite the parser with pegtl instead of flex/bison
this gives about 20% performance improvements on pure parsing. obviously
it'll be less on full eval, but depending on how much parsing has to be
done (eg whether nixpkgs haskell modules are included or not) it ranges
anywhere from 4% to 10% in our tests.

this has been tested with thousands of core hours of fuzz testing to
ensure that the ASTs produced by the new parser are exactly the same as
the ones produced by the old parser. error messages will
change (sometimes a lot) and are currently not perfect, but we'd rather
leave that open for improvement than having this work rot forever.

John Ericson 6910f5dcb6 Generate API docs with Doxygen
The motivation is as stated in issue #7814: even though the the C++ API
is internal and unstable, people still want it to be well documented for
sake of learning, code review, and other purposes that aren't predicated
on it being stable.

Fixes #7814

Robert Hensing 8648ebc2cc Add ./configure --disable-tests option
Building without tests is useful for bootstrapping with a smaller footprint
or running the tests in a separate derivation. Otherwise, we do compile and
run them.

This isn't fine grained as to allow picking `check` but not `installcheck`
or vice versa, but it's good enough for now.

I've tried to use Nixpkgs' `checkInputs`, but those inputs weren't discovered
properly by the configure script. We can emulate its behavior very well though.

John Ericson 16fa8c2e0e Fix configure.ac rapidcheck tests
- `AC_LANG_PUSH(C++)` is needed for the header check

- The library check is hopeless (without lots of third-party macros I
  don't feel like getting) because name mangling

Pkg-config would make all this easier. I previously opened
https://github.com/emil-e/rapidcheck/issues/302, I should write a PR
too.

Théophane Hufschmitt d1cda07ce4 Don't use -load_all on darwin
That flag breaks `-lc++fs` (introducing a duplicate symbol for some
reason). Besides, it was apparently needed for bzip2, but we're not using bzip2
anymore.

Eelco Dolstra 925b975224 Embed the sandbox shell into the statically linked 'nix' binary
With this, Nix will write a copy of the sandbox shell to /bin/sh in
the sandbox rather than bind-mounting it from the host filesystem.
This makes /bin/sh work out of the box with nix-static, i.e. you no
longer get

configure.ac: check for sandbox-shell's FEATURE_SH_STANDALONE
See also: https://bugs.archlinux.org/task/73998. Busybox's
FEATURE_SH_STANDALONE feature causes other busybox applets to
leak into the sandbox, where system() calls will start preferring
them over tools in $PATH. On arch, this even includes `ar`.

Let's check for this evil feature and disallow using this as a
sandbox shell.

Federico Pellegrin e9dbba0fc7 configure: explicit dependency on lowdown library
This dependency is used from quite a long time (now in libcmd) but
was not explicitly stated in the configure phase, possibly leading
to quite late build failures if that was not met (ie. building it
outside the .nix files provided). This MR adds it in the configure
phase so the failure is early and error is much more explicit.

Daniël de Kok 2de232d2b3 Add x86_64 compute levels as additional system types
When performing distributed builds of machine learning packages, it
would be nice if builders without the required SIMD instructions can
be excluded as build nodes.

Since x86_64 has accumulated a large number of different instruction
set extensions, listing all possible extensions would be unwieldy.
AMD, Intel, Red Hat, and SUSE have recently defined four different
microarchitecture levels that are now part of the x86-64 psABI
supplement and will be used in glibc 2.33:

https://gitlab.com/x86-psABIs/x86-64-ABI
https://lwn.net/Articles/844831/

This change uses libcpuid to detect CPU features and then uses them to
add the supported x86_64 levels to the additional system types. For
example on a Ryzen 3700X:

$ ~/aps/bin/nix -vv --version | grep "Additional system"
Additional system types: i686-linux, x86_64-v1-linux, x86_64-v2-linux, x86_64-v3-linux
