The nix::sys::mman::mmap documentation says
> Calls to mmap are inherently unsafe, so they must be made in an unsafe
block.
however, the function was not actually marked unsafe.
* `munmap` should also be `unsafe` for obvious reasons.
* `madvise` should be `unsafe` because of the MADV_DONTNEED flag.
* `mlock` was already marked `unsafe`
* `munlock` and `msync` don't strictly need to be `unsafe` despite
taking pointers AFAICT, but are marked `unsafe` for consistency and in
case they add additional flags in the future.

revents is an output field so regardless of what value it is set to it
will be overwritten by many of the function calls that take a PollFd.
The only value that makes sense for the caller to pass in in
`EventFlags::empty()` so we just hardcode that instead of making the
caller do it.

This allows importing them directly from `nix::fcntl` which is more
ergonomic than needing to use them via `FcntlArg`.

Improve AIO API
- Turn most `aio_*` functions into `AioCb` methods
- Add runtime checks to `AioCb` methods
- Implement `Drop` for `AioCb`

Add ppoll()
This will currently fail CI, as the necessary changes haven't hit libc yet. That is tracked in rust-lang/libc#537. This does build on my computer using the changes tracked on that PR, so I'd appreciate any visual review of this code as it should be "done".
I also wanted to get this submitted so hopefully it'd be in the queue for the 0.8 release.

Remove EPOLLWAKEUP and SIGEV_THREAD_ID when cross-compiling to MIPS.
With this nix builds for mipsel-unknown-linux-gnu.

Added BaudRate enum for termios
Issue #514
Does not provide `BaudRate::EXTA` or `BaudRate::EXTB` constants. These seem to alias to `B19200` and `B38400` respectively and so break the 1:1 mapping needed by `From`. I don't know their historic use.

This is possible now that EPOLLEXCLUSIVE was added to libc in
https://github.com/rust-lang/libc/pull/526

Also, fix style bug in AIO tests
|
|
New baud constants landed in rust-lang/libc#530, we'll use them.

Fix the style for bitflags!
Prefer `libc_bitflags!` over `bitflags!`. Prefer `libc::CONSTANTS` over
writing the constant manually.
This makes #501 unnecessary, since upstream now contains the `O_TMPFILE` constant.

Fix unresolved name error when building with musl.

Implement major/minor macros, correct mkdev
It appears that the previous `mkdev` was based on the kernel headers (https://github.com/torvalds/linux/blob/v4.7/include/linux/kdev_t.h#L6) which (I guess) is the internal kernel dev_t. Scrolling down the file you can see some bitshifting operations to do conversions.
The new implementation(s) are based on [musl](http://git.musl-libc.org/cgit/musl/tree/include/sys/sysmacros.h?id=dbbb3734d8c0176feabd6c46e2e85bbc3b8a60af) and [glibc](https://github.molgen.mpg.de/git-mirror/glibc/blob/20003c49884422da7ffbc459cdeee768a6fee07b/sysdeps/unix/sysv/linux/sys/sysmacros.h#L38), which are in agreement about how dev_t should be handled.
(as it happens I suspect we could omit the shift by 32 since I don't see that in the kernel headers, but doesn't hurt to take the conservative route and mimic the libcs)

wait: Support ptrace events for Linux
Adds new WaitStatus value `PtraceEvent`. Implementation of #273 that only affects Linux/Android.
|
|
If an AioCb has any in-kernel state, AioCb.drop will print a warning and
wait for it to complete.
|
|
Prevent immutable buffers from being used with aio_read or lio_listio
with LIO_READ. AioCb.from_slice no longer needs to be unsafe.

Add POSIX AIO support
POSIX AIO is a standard for asynchronous file I/O. Read, write, and
fsync operations can all take place in the background, with completion
notification delivered by a signal, by a new thread, by kqueue, or not
at all.
The SigEvent class, used for AIO notifications among other things, is
also added.

This introduces a wrapper for fchdir(2), allowing a process to change
directory based on an open file descriptor.
The underlying function is available in libc crate since 0.2.20.

Baed on discussions on the related PR, sethostname now takes
an `S: AsRef<OsStr>` in order to allow for a greater range of inputs
that allow for a more fluid interface.

Previously gethostname just mutated a buffer. We now provide
a slightly more usable (but still allocation free) API that ensures
that the returned buffer is NUL-terminated. We give back a `&CStr`
instead of requiring that the user do all of the conversions from
`&[u8]` when we know we are dealing with a `&CStr`.

Although the underlying C API does take a pointer to a set of
characters, it is a requirement of almost every operating system
that these bytes not contain a premature NUL character or other
special characters. In other words, you want a `&str`. Changing
this to make the API make a bit more sense.

fix #480 and add simple test cases for that.

Fix ControlMessage::encode_into when encoding multiple messages
copy_bytes updates dst so that it points after the bytes that were just
copied into it. encode_into did not advance the buffer in the same way
when encoding the data.
See #473

fix build for eventfd feature

Always use libc's socketaddr_storage
Since rust-lang/rust#23425 is closed, we no longer need the special
case.
