mac time.h functions
I used these in https://github.com/shua/graf because I'm used to them, and don't really want to pull in time or chrono just for some stuff already present in libc.h . Compilation worked fine on my linux target, but failed on mac osx because these weren't defined in rust-lang/libc (but these are all present in 13.1 SDK).

linux: add kexec flags
This adds `KEXEC_ARCH_MASK`, `KEXEC_FILE_NO_INITRAMFS`, `KEXEC_FILE_ON_CRASH`, `KEXEC_FILE_UNLOAD`, `KEXEC_ON_CRASH`, and `KEXEC_PRESERVE_CONTEXT` constants on Linux and Android.
Those are used by `kexec` and `kexec_file_load` syscalls.

Add OpenBSD CLOCK_* constants
To compile [`wasmer-wasi`](https://github.com/wasmerio/wasmer/tree/master/lib/wasi) crate (part of Wasmer) on OpenBSD, I need to add CLOCK_* constants from `/usr/include/sys_time.h` file.
- Add CLOCK_* constants in `src/unix/bsd/netbsdlike/openbsd/mod.rs`
- Update `libc-test/semver/openbsd.txt` accordingly

Fix `SOCK_SEQPACKET` and `MAP_SYNC` on musl powerpc and s390.
- On powerpc musl, add definitions for `MAP_HUGETLB` and `MAP_SYNC`.
- On powerpc64 musl, add a definition for `SOCK_SEQPACKET`.
- On s390x musl, add definitions for `SOCK_SEQPACKET` and `MAP_SYNC`.
- On mips, just move the existing `MAP_HUGETLB` definition to be near the other `MAP_*` constants.

Add reentrant glibc getmntent_r

- \[x] `rustc ci/style.rs && ./style src`
- \[ ] `cd libc-test && cargo test` (This might fail on your env due to environment difference between your env and CI. Ignore failures if you are not sure.)
<details>
<summary>**Maybe**, see the cargo test output -- I am unsure about the failures</summary>

linux: move DCCP_ constants from linux/gnu to linux
closes #3132
these constants come from linux headers, so they should be exposed for "linux", not just glibc.
this change exposes them for linux/musl and linux/uclibc.
of note, android contains these same constants, but moving it to linux-like would also expose them on emscripten, which does not have it.
(not sure if things are placed in the correct place, but this looks like an okayish start)

Add support for the unstable `check-cfg` feature behind an environment variable
`check-cfg` ([Rust](https://doc.rust-lang.org/stable/unstable-book/compiler-flags/check-cfg.html), [Cargo](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#check-cfg)) is an unstable features that warns when you write an unknown `#[cfg]` (likely due to a typo). The feature works out of the box for default cfgs and features provided by Cargo, but requires providing the list of extra cfgs when custom ones are used.
This PR adds the `LIBC_CHECK_CFG` environment variable. When enabled, the build script will use the `cargo:rustc-check-cfg` println to instruct the compiler of all the possible cfgs set by libc. The build script was also refactored to ensure all cfgs are accounted for, and a CI job using `-Z check-cfg` was added.
This PR is best reviewed commit-by-commit.
## Why is this needed?
The main motivation for this PR is that `rust-lang/rust` enforces `check-cfg` across the whole codebase. Normally this is not a problem for dependencies like `libc`, as Cargo caps the lints and thus doesn't show the generated warnings.
When developing support for new targets though, it's helpful to use a custom libc fork to develop the libc port and the std port together. Unfortunately doing that today results in a bunch of compilation errors, since lints are not capped with `path` dependencies. My goal with this PR is to address that shortcoming, as we'd then be able to set the `LIBC_CHECK_CFG=1` environment variable in the Rust build system and remove the compilation errors.
This PR might also be helpful for libc maintainers, as the CI check might spot typos in `#[cfg]`s.

add S_IRWX* constants to wasi
It seems like all other platforms have `/S_IRWX[OGU]/`, and the `libc` crate looks for them, but they were missing in WASI.

Add support for OpenHarmony
This PR adds support for [OpenHarmony](https://gitee.com/openharmony/docs/) targets:
- `aarch64-linux-ohos`
- `arm-linux-ohos`
Compiler team MCP: https://github.com/rust-lang/compiler-team/issues/568
OpenHarmony uses a fork of musl with minor modifications, so most of the code is shared with other musl targets. Additionally, although OpenHarmony uses musl 1.2, it is still ABI-compatible with musl 1.1 so the existing bindings should continue to work until https://github.com/rust-lang/libc/pull/3068 is merged.
A PR to add the targets to rustc will follow after this is merged.

linux/musl: add copy_file_range syscall wrapper
musl supports copy_file_range since v1.1.24, so expose the corresponding wrapper here too.
