ci/semver.sh: Pass --locked when installing semverver
We don't, in general, want our CI to be the testbed for building
semverver with newer versions of its dependencies. Pass --locked to use
the checked-in Cargo.lock instead.
This works around https://github.com/rust-lang/cargo/issues/9101 .

Remove link directives for libutil on linux-gnu targets
These are all handled in src/unix/mod.rs now, which also addresses the
crt-static case; no linux-gnu target should have any link directives in
any other module.
This fixes static linking with glibc for various architectures.

Add port_notify struct for illumos and Solaris
This adds a missing struct for configuring event ports notifications. The `libc-test` suite passes on illumos (OmniOSCE) and is assumed to pass on Solaris, given that the interface has been present since Oracle forked from OpenSolaris.
Add timer interface for illumos and Solaris
This adds the `timer_*` family of functions present in illumos (and Solaris), along with the associated types. The `libc-test` suite passes on an illumos (OmniOSCE) machine. While I do not have resources available to test on Solaris, these interfaces have been stable since Oracle forked.
Add preadv and pwritev for macOS
Add declarations for the preadv and pwritev system calls, introduced
in macOS 11.0 (Big Sur).

Fix missing dl lib on armv5te-unknown-linux-uclibceabi
I'm unable to link my executable for the Linux uClibc environment because of some missing symbols from the dl lib:
```
/home/operutka/goodcam/goodcam-server/target/armv5te-unknown-linux-uclibceabi/release/deps/goodcam_server-aefb92c403e8cd55.goodcam_server.dzc3futp-cgu.0.rcgu.o: In function `mio::sys::unix::dlsym::fetch::he5e2964820cfd29d':
goodcam_server.dzc3futp-cgu.0:(.text._ZN3mio3sys4unix5dlsym5fetch17he5e2964820cfd29dE+0x30): undefined reference to `dlsym'

goodcam_server.dzc3futp-cgu.0:(.text._ZN3std3sys4unix4weak5fetch17h5ed4b0fa5792ef5cE+0x3c): undefined reference to `dlsym'
```
The libc crate is being used at both of these points.
This change fixes the issue for me. I've tested it with two different GCC cross toolchains for armv5te and it seems to be OK.
_Note: I'm building my own std using the unstable build-std Cargo feature._
Fix CI on `i686-unknown-linux-musl`
I suspect `focal-20210119` breaks the build, uses an older image to fix the `Could not configure 'libc6:i386'` failure.
openbsd: make WIFCONTINUED() safe
it seems it was a missed part of #1891
Found it because rustc -nightly started to use `libc::WIFCONTINUED()` recently in a safe context and the build fail to build on OpenBSD.
Fixes#2001
Fix error when building rustc with a custom libc
When pulling a custom `libc` into a `rustc` build (with the `rustc-dep-of-std` feature set), the following error occurs:
```
error: unused attribute
--> /hdd/libc/src/lib.rs:29:1
|
29 | #![no_std]
| ^^^^^^^^^^
|
= note: `-D unused-attributes` implied by `-D warnings`
error: crate-level attribute should be in the root module
--> /hdd/libc/src/lib.rs:29:1
|
29 | #![no_std]
| ^^^^^^^^^^
```
I think this is because both the `no_std` and `no_core` attributes are specified, although the error message doesn't make this very clear. This PR changes this so `no_std` is only supplied when the `rustc-dep-of-std` feature is not.
Define basic Linux SocketCAN constants and types
Add definitions from `linux/can.h`, which is a "base" header for remainder of SocketCAN functionality.
CAN bus (ISO-11898) is a communication standard used in automotive, automation and industrial solutions. Linux provides a socket-like interface to access raw CAN and protocols based on CAN, such as ISO-TP(ISO-15765) or SAE-J1939.

Make test suite pass on macOS on aarch64
While working on #2007 I tried to run `cargo test` in `libc-test`, which failed, because the definition of `__darwin_mcontext64` was incomplete (see #1990). This adds definitions for the exception state and the floating point state as well.
`libc-test` still does not pass, because I use the type `[u128; 32]` for the `__v` field of `__darwin_arm_neon_state64` (in C it is `__uint128_t __v[32]`. `ctest2` does not translate `u128` to `__uint128_t` and the generated C code does not compile. Any ideas for working around this?
aio functions do not require librt on FreeBSD
On FreeBSD, the aio_ functions require librt _only_ if they use
SIGEV_THREAD completion notification. However, due to Rust's originally
poor support for C unions, libc doesn't even expose some of the fields of
struct sigevent that SIGEV_THREAD requires. Accordingly, there is no
need to link librt to programs using aio via libc.
This change partially reverts 8c23f77704
from PR #1630 .
While I'm here, fix the linkage of lio_listio on DragonflyBSD. It
_does_ require librt.
