Use '&&' on travis, not ';'

Closes #258

Fix CPU_SET and CPU_ISSET

Use now available link name "signal" instead of "bsd_signal"

On android, the `bsd_signal` is gone, the `signal` is available.

While this is the most obvious solution, I am not sure of a few things:
- How are we going to keep compatibility with older NDKs where `signal` does not exist;
- Was something dependent on this being different on android and thus would break (for example, the rust compiler uses this function, so it may break somewhere).

Fixes #236.

Remove iOS doc links from README

Fixes #243

langinfo bindings and defs

There are many constants defined by langinfo, but we have the
new types, locale_t and nl_item.

We also have several functions, not all of which exist for every
platform:

nl_langinfo
nl_langinfo_l
newlocale
duplocale
freelocale
uselocale
querylocale

Add RTLD_DEFAULT to more platforms

Link to libraries when disabling `use_std`

This crate currently relies on libraries being linked to come from libstd, but
if `use_std` is disabled that's not true! In that case we need to pull in the
libraries ourselves.

Closes rust-lang/rust#32661

On non-musl Linux, strerror_r should be linked to __xpg_strerror_r

Currently `libc::strerror_r()` wrongly returns a `c_char` pointer as a large `c_int`.

Also exclude `MS_RMT_MASK` from `libc-test`.

Add several pthread functions for DragonFly/FreeBSD

These are needed in order to fix/implement the guard page code of Rust
for DragonFly.

Add clock_getres(3) and improve clockid_t constants.

This is still a draft

It was updated recently, so the test is known to fail depending on the
libc version of the test environment.

unix: Add openpty(3) and forkpty(3) for non-Apple platforms

The functions were added for Apple in #202. Adding them to other
platforms was pending an amendment to RFC 1291 to expand the scope of
libc to include libutil. The amendment was merged as
  https://github.com/rust-lang/rfcs/pull/1529

Add lconv type, and locale support for UNIX

We have lconv struct, setlocale(), and localeconv(). Constants live
under notbsd for now.

Linux-likes have more locale categories than the BSDs (except for
musl). We define the common set of categories at the
src/unix/notbsd/mod.rs level, and leave the rest to the
platform-specific modules.

The BSDs seem to have more peculiarities than the notbsds

Bump to 0.2.9

Swap header/footer... dunno how they got that way?

Apparently they were swapped accidentally already!

Closes #240

Lint caught a long line. This should fix the CI failure.

linux: Add missing Linux-specific fcntls

Also move F_DUPFD_CLOEXEC up a level as it is available on Android.

Also move F_DUPFD_CLOEXEC up a level as it is available on Android.

This commit leaves file sealing related fcntls and bitflag constants
out, as they are defined in `linux/fcntl.h` rather than `fcntl.h`. They
can be included once an approach for verification has been figured out.
See #235 for more detail.
