When reading a value into an enum from getsockopt, we must validate it.
Failing to do so can lead to UB for example with SOCK_PACKET on Linux.
Perform the validation in GetSockOpt::get. Currently SockType is the
only type that requires validation.
Fixes #1819

Clippy is now smarter about detecting unnecessary casts and
useless conversions, which means we need to be more explicit
about when the conversions are needed for a subset of platforms.
Required changes found by repeatedly running the following command
against a list of the supported platforms.
`xargs -t -I {} sh -c "cargo clippy -Zbuild-std --target {} --all-targets -- -D warnings || exit 255"`
I removed the casts it complained about, and then restored them
with an `#[allow]` if a later target needed the cast.

Remove obsolete references to target_env = wasi, target_os = nacl,
target_os = osx, and a typo'd target_os = fushsia that didn't compile
when fixed.
- target_env = wasi is dead: https://github.com/rust-lang/rust/pull/60117
- target_os = nacl is dead: https://github.com/rust-lang/rust/pull/45041
- target_os = osx is dead, but I can't find a link.

* enabled as much functionality and defines that match
updated libc definitions for haiku

It just so happens that Redox, OpenBSD, Dragonfly, and uclibc don't use
some of the rules for two internal macros.
|

IP_DONTFRAG: iOS, macOS
IPV6_DONTFRAG: android, iOS, linux and macOS
Test: `cargo test --test test dontfrag_opts`
Some CI tests running ENOPROTOOPT are disabled (qemu-based).

Using features reduces build time and size for consumer crates. By
default all features are enabled.

They were properly marked as unsafe as originally written. However,
when the internal mem::zeroed() was replaced by mem::uninitialized(),
these traits actually became safe. Only Get::assume_init() is actually
unsafe. Fixes a warning with the latest Clippy.

This macro is not exported outside of the crate, so there's no danger.

Test: `cargo test --test test test_ttl_opts`

Setting these options enables receiving errors, such as ICMP errors from
the network, via `recvmsg()` with `MSG_ERRQUEUE`.
Adds new `Ipv{4,6}RecvErr` variants to `ControlMessageOwned`. These
control messages are produced when `Ipv4RecvErr` or `Ipv6RecvErr`
options are enabled on a raw or datagram socket.
New tests for the functionality can be run with `cargo test --test test
test_recverr`.
This commit builds on an earlier draft of the functionality authored by
Matthew McPherrin <git@mcpherrin.ca>.

On FreeBSD and its derivatives, this socket option gets the credentials
of the connected peer.

This PR implements support of RXQ_OVFL flag and parsing ControlMessage
to get the packet drop counter of UDP socket.

Without this commit, nix doesn't currently compile on OpenBSD. Some keepalive
settings can be set globally, but not per-socket (see e.g.
https://bugzilla.mozilla.org/show_bug.cgi?id=970550 for some digging into this).
Since it seems that NetBSD and DragonflyBSD have these settings, it makes more
sense to only exclude them on OpenBSD rather than include them on (pretty much
every) other operating systems.

This is available only on Linux as far I know,
[socket(7)](https://linux.die.net/man/7/socket) has some information
about the `SO_BINDTODEVICE` sockopt. In simple words it binds a socket
to an specific network device (specified as an string like "wlo1",
"eth0", etc.), to only process packets from that device.

The old code tried to zero-initialize an enum for which 0 is not a valid
value. That worked for older compilers, but triggers a panic with Rust
1.44.0. The correct technique is to use mem::MaybeUninit.
Fixes #1212

`assert_eq!` gives more debug info when the test fails by default than
`assert!`. This should help make debugging easier.
