lints: Remove `allow(dead_code)`

As discussed in [1], some changes to dead code warnings caused a lot of
code to be inaccurately reported as dead in `libc`. The change was
reverted and improved since then, so we no longer need to skip this
check.

Includes some changes to make things pass with the lint.

Replace handwritten `Debug` impls with derives

`s_no_extra_traits!` doesn't derive `Debug` so there are a lot of
handwritten implementations. However, since we have a derive-like
solution for unions now (printing them like an opaque struct), there
really isn't any reason these can't all be derived.

Add `derive(Debug)` to `s_no_extra_traits`, still gated behind `feature
= "extra_traits"`, which allows getting rid of manual implementations.

solarish: define `IP_BOUND_IF` and `IPV6_BOUND_IF`

These socket options are currently defined only on macOS and friends,
but they exist on illumos and Solaris as well.

This commit defines these socket options on solarish operating systems.

On Solaris, see the man page [`ip(7P)`].

I'd like to provide a link to the illumos manual pages, but apparently
https://illumos.org/man seems to be impacted by today's AWS outage.

The constants are defined in `/usr/include/netinet/in.h`:

```

[solarish/illumos] add the posix_spawn family of functions

Add definitions from `spawn.h` as present [in illumos-gate (blame
view)][spawn-h]. I added definitions more than 15 years old to
`solarish/mod.rs`, and others to `solarish/illumos.rs`.

There are a lot of definitions here -- it's easiest to look at them in the
blame view linked above. But here are the corresponding man pages:

For solarish:

* [`posix_spawn`, `posix_spawnp`](https://illumos.org/man/3C/posix_spawn)
* [`posix_spawn_file_actions_{init,destroy}`](https://illumos.org/man/3C/posix_spawn_file_actions_init)
* [`posix_spawn_file_actions_{addopen,addclose}`](https://illumos.org/man/3C/posix_spawn_file_actions_addopen)
* [`posix_spawn_file_actions_adddup2`](https://illumos.org/man/3C/posix_spawn_file_actions_adddup2)
* [`posix_spawn_file_actions_addclosefrom_np`](https://illumos.org/man/3C/posix_spawn_file_actions_addclosefrom_np)
* [`posix_spawnattr_{init,destroy}`](https://illumos.org/man/3C/posix_spawnattr_init)
* [`posix_spawnattr_{setflags,getflags}`](https://illumos.org/man/3C/posix_spawnattr_setflags)
* [`posix_spawnattr_{setpgroup,getpgroup}`](https://illumos.org/man/3C/posix_spawnattr_setpgroup)
* [`posix_spawnattr_{setschedparam,getschedparam}`](https://illumos.org/man/3C/posix_spawnattr_setschedparam)
* [`posix_spawnattr_{setschedpolicy,getschedpolicy}`](https://illumos.org/man/3C/posix_spawnattr_setschedpolicy)
* [`posix_spawnattr_{setsigdefault,getsigdefault}`](https://illumos.org/man/3C/posix_spawnattr_setsigdefault)
* [`posix_spawnattr_{setsigignore,getsigignore}_np`](https://illumos.org/man/3C/posix_spawnattr_setsigignore_np)
* [`posix_spawnattr_{setsigmask,getsigmask}`](https://illumos.org/man/3C/posix_spawnattr_setsigmask)

Newer functions added independently to Solaris and illumos:

* [`posix_spawn_file_actions_{addchdir,addchdir_np,addfchdir}` on Solaris](https://docs.oracle.com/cd/E88353_01/html/E37843/posix-spawn-file-actions-addchdir-np-3c.html)

* The illumos-only functions are quite recent so the man pages haven't been
uploaded to illumos.org yet. But [here's the one for `addchdir` and
`addfchdir`](https://github.com/illumos/illumos-gate/blob/7633a05bff8c639f2df722d1fba7b889b2763d3d/usr/src/man/man3c/posix_spawn_file_actions_addchdir.3c).
Note that the `_np` functions are not documented in the manual, but they are
available for compatibility.

The one function I skipped over was
[`posix_spawn_pipe_np`](https://illumos.org/man/3C/posix_spawn_pipe_np) -- it
seemed a bit niche and I wasn't quite sure how to model `boolean_t`.
