Edit: Converted to staging PR at #243161

Re-open of #237449, this time without accidentally subscribing many reviewers because of the wrong source branch in the PR.

Description of changes

Supports #61575.

The fact that these libs currently force-disable shared libraries when static ones are enabled was found during working on nh2/static-haskell-nix#116.

FYI @jonathanlking @aherrmann

Is the purpose of this only to avoid a rebuild? If so, isn't it more important to keep the code simple?

Yes, the usage of else null is.

With a rebuild, the entirety of nixpkgs would be rebuilt, so ofborg could not build it, this commit could not be cherry-picked easily, and it would have to target staging.

I am thinking that a followup PR to staging that removes else null could do the code simplification. But happy to hear others' opinions!

pypy3Packages.execnet: disable tests as they randomly crash, cleanup
The configure scripts frequently use `main` returning an implicit `int`,
which causes spurious failures when CC is clang 16+. This is fixed by
patching the provided macros and regenerating the scripts with
autoreconfHook, though it requires some manual processing (see below).

The upstream `configure.ac` is written in such a way that it requires
fixups and post-processing.

* Fixups are required because the original build process just cats the
  macros together into one file. When `aclocal` is run, it does not pick
  up all of them. This is worked around by catting the missing macros to
  a file that is picked up by autoreconfHook.
* Post-processing is required to populate the version information. This
  is done in a subshell to avoid polluting the environment with the
  contents of `RELEASE`. Otherwise, the build will fail because the
  version C macros it expects will not be defined.
Both `_spin_lock_try` and `_spin_unlock` are private and deprecated
APIs, which are not exported by any headers in the SDK. The build fails
because the configure script does not define the functions before
calling them, which is treated as error by clang 16.

This patch replaces use of those APIs with `os_unfair_lock`, which is
the recommended replacement per the deprecation messages.
In preparation for bumping the LLVM used by Darwin, this change
refactors and reworks the stdenv build process. When it made sense,
existing behaviors were kept to avoid causing any unwanted breakage.
However, there are some differences. The reasoning and differences are
discussed below.

- Improved cycle times - Working on the Darwin stdenv was a tedious
  process because `allowedRequisites` determined what was allowed
  between stages. If you made a mistake, you might have to wait a
  considerable amount of time for the build to fail. Using assertions
  makes many errors fail at evaluation time and makes moving things
  around safer and easier to do.
- Decoupling from bootstrap tools - The stdenv build process builds as
  much as it can in the early stages to remove the requirement that the
  bootstrap tools need bumped in order to bump the stdenv itself. This
  should lower the barrier to updates and make it easier to bump in the
  future. It also allows changes to be made without requiring additional
  tools be added to the bootstrap tools.
- Patterned after the Linux stdenv - I tried to follow the patterns
  established in the Linux stdenv with adaptations made to Darwin’s
  needs. My hope is this makes the Darwin stdenv more approable for
  non-Darwin developers who made need to interact with it. It also
  allowed some of the hacks to be removed.
- Documentation - Comments were added explaining what was happening and
  why things were being done. This is particular important for some
  stages that might not be obvious (such as the sysctl stage).
- Cleanup - Converting the intermediate `allowedRequisites` to
  assertions revealed that many packages were being referenced that no
  longer exist or have been renamed. Removing them reduces clutter and
  should help make the stdenv bootstrap process be more understandable.
swift-corelibs fails to build due to a missing header and an invalid
pointer conversion. Patches are provided to fix both of these issues.
Switching the build system to cmake makes it easier to make changes to
the build (particularly which dependencies to link). It also removes a
lot of manual build steps and fixes the issue identified by @emilazy in
NixOS#238791.

Fixes NixOS#238791.
Upstream swift-corelibs links against icu on Linux, so it is not
necessarily tied to the version of ICU provided by Apple for Darwin.

swift-corelibs and qtwebkit are the only two packages that link against
darwin.ICU. Switching to the nixpkgs icu will allow the Darwin-specific
package to be deprecated and removed eventually.
swift-corelibs uses libcurl to implement `NSURLSession` in Foundation
via the symbols exported by CF. Foundation is not build on Darwin, and
these symbols are not exported by the system CoreFoundation.

By not linking against libcurl, this breaks a cycle between CF and
libcurl. That should allow libcurl to drop the patch disabling
linking against the SystemConfiguration and restore NAT64 support.

Unfortunately, the Darwin stdenv bootstrap still needs to build
dependencies that use `fetchFromGitHub`. While it can drop curl from the
final stdenv, it still needs to use it during the stdenv bootstrap.
@emilazy found a bug in NixOS#234861. Specifically, the hook is not actually
applied. e2fsprogs links against darwin.CF, but since it cannot find the
framework by rpath, it crashes.

Since the hook should always be used, it is copied directly to
`nix-support/setup-hook` instead of providing it as an attribute. This
preserves dropping the hook in the cross-compilation case while
providing it for everything else that needs it.

To avoid further churn and due to the complexity of building the stdenv
with the hook active, this change required the stdenv rework.

Closing to make a new PR for staging without notifying lots of people.

Edit: Bah, the close operation reverted itself after a minute with Github 's You cannot comment at this time, so it didn't actually go through, and people got still pinged by my force-push :(
