6a5a295019 Port wasi-common from unsafe-io to io-lifetimes (#3049) 
* Port wasi-common to io-lifetimes.

This ports wasi-common from unsafe-io to io-lifetimes.

Ambient authority is now indicated via calls to `ambient_authority()`
from the ambient-authority crate, rather than using `unsafe` blocks.

The `GetSetFdFlags::set_fd_flags` function is now split into two phases,
to simplify lifetimes in implementations which need to close and re-open
the underlying file.

* Use posish for errno values instead of libc.

This eliminates one of the few remaining direct libc dependencies.

* Port to posish::io::poll.

Use posish::io::poll instead of calling libc directly. This factors out
more code from Wasmtime, and eliminates the need to manipulate raw file
descriptors directly.

And, this eliminates the last remaining direct dependency on libc in
wasi-common.

* Port wasi-c-api to io-lifetimes.

* Update to posish 0.16.0.

* Embeded NULs in filenames now get `EINVAL` instead of `EILSEQ`.

* Accept either `EILSEQ` or `EINVAL` for embedded NULs.

* Bump the nightly toolchain to 2021-07-12.

This fixes build errors on the semver crate, which as of this writing
builds with latest nightly and stable but not 2021-04-11, the old pinned
version.

* Have cap-std-sync re-export ambient_authority so that users get the same version.

c881c01cde Increase timeout for poll_oneoff tests 
This increases the timeout from 50ms to 200ms, which makes the
tests reliably pass on my machine using the CI scripts againt
the s390x-linux-user qemu target.

b7efcbe80f jump through enough hoops for the poll lifetime to work out 
you program rust for a few years and you think you're done tearing your
hair out over lifetimes, well, you'll find yourself wrong

6b40724d18 Support "sleep" forms of poll_oneoff. 
Add support for `poll_oneoff` calls which just sleep on a relative
timeout. This fixes a bug handling code compiled with WASI libc's `sleep`
family of functions, which call `poll_oneoff` with a `CLOCK_REALTIME`
timer, which wasn't previously implemented.

2d3f2adf04 Fix nondeterministic failures in poll_oneoff_stdio. 
Adjust this test so that it tolerates poll_oneoff returning that both a
timeout occurred and an input is ready for reading, at the same time.

bc95864202 wasi-tests: add path_exists test

https://github.com/bytecodealliance/wasmtime/issues/2642 but it does
not, so the problem has something to do with invoking via wasmtime cli?
