Update to the latest wasi-sysroot.
- Rename `wasm32-unknown-wasi` to `wasm32-wasi`.
- `__wasilibc_rmfileat` was renamed to `__wasilibc_unlinkat`
- Add bindings for a few more functions and typedefs.

This target is [being proposed][LINK] int he rust-lang/rust repository
and this is intended to get coupled with that proposal. The definitions
here all match the upstream reference-sysroot definitions and the
functions all match the reference sysroot as well. The linkage here is
described more in detail on the Rust PR itself, but in general it's
similar to musl.
Automatic verification has been implemented in the same manner as other
targets, and it's been used locally to develop this PR and catch errors
in the bindings already written (also to help match the evolving sysroot
of wasi). The verification isn't hooked up to CI yet though because
there is no wasi target distributed via rustup just yet, but once that's
done I'll file a follow-up PR to execute verification on CI.

cleanup libc-test for OpenBSD
here a cleanup for libc-test for OpenBSD
Some elements (compat for old and now unsupported OpenBSD versions) could be removed, but I think it is better to address them after this PR is merged.
the testsuite for OpenBSD still pass with it (well, with #1280)

This cleans up the build.rs of `libc-test` for apple targets.
I wanted to update the docker containers of some targets so that we can start
testing newer currently-skipped APIs properly, but it is impossible to figure
out which headers and APIs are skipped for each target.
This PR separates the testing of apple targets into its own self-contained
function. This allows seeing exactly which headers are included, and which items
are skipped. A lot of work will be required to separate the testing of all major
platforms and make the script reasonable.
During the clean up, I discovered that, at least for apple targets, deprecated
but not removed APIs are not tested. I re-enabled testing for those, and fixed
`daemon`, which was not properly linking its symbol. I also added the
`#[deprecated]` attribute to the `#[deprecated]` APIs of the apple targets. The
attribute is available since Rust 1.9.0 and the min. Rust version we support is
Rust 1.13.0.
Many other APIs are also currently not tested "because they are weird" which I
interpret as "the test failed for an unknown reason", as a consequence:
* the signatures of execv, execve, and execvp are incorrect (see
https://github.com/rust-lang/libc/issues/1272)
* the `sig_t` type is called `sighandler_t` in libc for some reason:
https://github.com/rust-lang/libc/issues/1273
This probably explains why some other things, like the
`sa_handler`/`sa_sigaction` fields of `sigaction` were skipped. The field is
actually a union, which can be either a `sig_t` for the `sa_handler` field, or
some other type for the `sa_sigaction` field, but because the distinction was
not made, the field was not checked.
The latest ctest version can check volatile pointers, so a couple of skipped
tests are now tested using this feature.
