* add cross-references to `nix-path` overriding
while this information is already present in the settings, it's more
likely to be first accessed through the "lookup path" page, which
currently requires following two links to get to the practically
important bits.

This is because with the split packages of the Meson build, we simply
have no idea what directory the binaries will be installed in when we
build the library.
In the process of doing so, consolidate and make more sophisticated the
logic to cope with a few corner cases (e.g. `NIX_BIN_DIR` exists, but no
binaries are inside it).

In d60c3f7f7c, this was changed to close a
hole in the sandbox. Unfortunately, this was too restrictive such that it
made local port binding fail, thus making derivations that needed
`__darwinAllowLocalNetworking` gain nearly nothing, and thus largely
fail (as the primary use for it is to enable port binding).
This unfortunately does mean that a sandboxed build process can, in
coordination with an actor outside the sandbox, escape the sandbox by
binding a port and connecting to it externally to send data. I do not
see a way around this with my experimentation and understanding of the
(quite undocumented) macOS sandbox profile API. Notably it seems not
possible to use the sandbox to do any of:
- Restrict the remote IP of inbound network requests
- Restrict the address being bound to
As such, the `(local ip "*:*")` here appears to be functionally no
different than `(local ip "localhost:*")` (however it *should* be
different than removing the filter entirely, as that would make it also
apply to non-IP networking). Doing `(allow network-inbound (require-all
(local ip "localhost:*") (remote ip "localhost:*")))` causes listening
to fail.
Note that `network-inbound` implies `network-bind`.
This ended up motivating a good deal of other infra improvements in
order to get Windows right:
- `OsString` to complement `std::filesystem::path`
- env var code for working with the underlying `OsString`s
- Rename `PATHNG_LITERAL` to `OS_STR`
- `NativePathTrait` renamed to `OsPathTrait`, given a character template
parameter until #9205 is complete.
Split `tests.cc` matching split of `util.{cc,hh}` last year.

The test split matches PR #8920, so the utility files and tests files
are once again to 1-1. The string changes continues what was started in
PR #11093.
In the FFI world we have many tools that are not gcc/clang and therefore
not always support the latest C standard. This fixes support with cffi
i.e. used in https://github.com/tweag/python-nix
It was failing with:
error: AWS error fetching 'nix-cache-info': The specified bucket does not exist
because `S3BinaryCacheStoreImpl` had a `bucketName` field that
shadowed the inherited `bucketName from `S3BinaryCacheStoreConfig`.
