add DT_UNKNOWN
The `d_type` field of `struct dirent` can be `DT_UNKNOWN` if a
filesystem doesn't support returning the file type in directory entries.
Linux's readdir(3) man page, for example, says: "Currently, only some
filesystems [...] have full support for returning the file type in
d_type. All applications must properly handle a return of DT_UNKNOWN."

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.
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.
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.

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.
