Add sockaddr_ctl on Mac

Add killpg

added EPOLL(5)  for Illumos (Solaris fork)

EPOLL(5)  is being used in crates like mio and iovec , this change allows those crates and other that depends on EPOLL(5)  to be built in illumos systems.

Difftime

Once merged, can you update the crate too please?

feat(linux): add mntent struct and related functions

Useful when playing around with mounting points, sadly not a common interface. :(

Minor fixes for CloudABI ARM support

In the initial set of fixes for CloudABI, it looks like support for 32-bit ARM was left out, even though it is supported for C/C++. While there, fix up `c_char` for ARM64, which currently has the wrong sign.

On ARM64, it is supposed to be unsigned char:

  $ aarch64-unknown-cloudabi-cc -dM -E - < /dev/null | grep __CHAR_UNSIGNED__
  #define __CHAR_UNSIGNED__ 1

Add time_t for CloudABI.

Even though this data type is not used by libstd in any platform
independent code, one of the unit tests in src/libstd/time/mod.rs refers
to it. Instead of making that unit test more complicated, simply add
time_t, matching the type used by the C library.

Bump to 0.2.35

Bump for EAI_* names.

Add _SC_NPROCESSORS_ONLN for CloudABI.

This constant is not used by the C library, which is why I didn't add it
initially. It is, however, used by libtest to determine the parallelism
for the execution of tests.

Add support for CloudABI.

CloudABI is a sandboxed UNIX-like runtime environment, based on the
principle of capability-based security. As CloudABI is intended to be
cross-platform, the system call layer is specified here:

    https://github.com/NuxiNL/cloudabi/blob/master/cloudabi.txt

From these definitions, we automatically generate C and Rust bindings.
The latter is published on crates.io:

    https://crates.io/crates/cloudabi

My goal is to implement libstd for CloudABI in such a way that it uses
the C library as little as possible; only in places where it would ease
interfacing with C code (e.g., thread creation). In places where
constants in the C library are directly based on the CloudABI
specification (e.g., errnos), use the constants provided by the cloudabi
crate.

These are now used by libstd's termination.rs.
