672: add poll module in Android r=Susurrus
`poll` functions are defined in Android as well.
libc is missing some constant, but once rust-lang/libc#663 is merged, it'll be good to merge here.
Closes #711

The recommended way to trace syscalls with ptrace is to set the
PTRACE_O_TRACESYSGOOD option, to distinguish syscall stops from
receiving an actual SIGTRAP. In C, this would cause WSTOPSIG to return
SIGTRAP | 0x80, but nix wants to parse that as an actual signal.
Add another wait status type for syscall stops (in the language of the
ptrace(2) manpage, "PTRACE_EVENT stops" and "Syscall-stops" are
different things), and mask out bit 0x80 from signals before trying to
parse it.
Closes #550

630: Add wrappers for sysconf(3), pathconf(2), and fpathconf(2) r=asomers

Nothing that nix currently binds is architecture-specific, and Android
supports ptrace just as much as non-Android Linux.
|
|
the previous definition were linux specific.

The officially documented type, and the type in sched.h, for this
argument is pid_t.

Some ptrace functions return structures through the data argument. This commit adds utilities to return data through this mechanism and function specialisations for a few of these functions (getting event messages or the siginfo_t struct). Once the next version of libc is released these utilities will be expanded to include the fpregs and user_regs structs.
Ptrace requests that are now satisfied by a more specific public function will return an unsupported operation error. This has involved adding an UnsupportedOperation to the nix::Error enum and removed the mapping from Error to Errno and from Error to std::io::Error.

564: select.rs FdSet: method `contains' should not mutate anything r=posborne
The method does not change anything, so I updated the type signature. Tests pass.

v0.8.1 was released to fix the broken build on FreeBSD. It is v0.8.0
with a859ee3 cherry-picked.

581: Fix syntax for changelog and add missing feature r=Susurrus
|
|
The existing AioCb constructors work for simple programs where
everything is stored on the stack. But in more complicated programs the
borrow checker can't prove that a buffer will outlive the AioCb that
references it. Fix this problem by introducting
AioCb::from_boxed_slice, which takes a reference-counted buffer.
Fixes #575

Remove revents from PollFd::new
I could've used a `0i16`here as well but I liked the better semantics of `empty()`.
|
|
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.

closes #519
|
|
This allows importing them directly from `nix::fcntl` which is more
ergonomic than needing to use them via `FcntlArg`.
