Copy them into individual platform files instead. Fixes musl build.

solaris: add dlsym/dlopen RTLD constants

These constants are taken from OpenIndiana's `dlfcn.h`.  In particular,
`RTLD_DEFAULT` is now needed in `fetch` for std's weak symbol support.

Bump to 0.2.14

Add SIGCHLD and other signals

Added linger struct

Add SIGCHLD, SIGSTOP, SIGTSTP, SIGCONT, SIGTTIN, SIGTTOU. Improve
consistency across oses, by adding SIGEMT to relevant oses.

Add epoll_create1.

Add strdup extern

enhance pathconf constants to cover the most common constants

Add missing consts for Solaris/Illumos

linux: /usr/include/bits/confname.h (taken from redhat, checked against https://github.com/cpc26/abi_linux/blob/master/linux-abi/branches/IBCS3/cxenix/pathconf.c)
android: https://android.googlesource.com/platform/development/+/android-4.3_r1.1/ndk/platforms/android-3/include/pathconf.h
mac: taken from /usr/include/sys/unistd.h

Bump to 0.2.13

unix: Add lchown

Add SEEK_DATA/SEEK_HOLE constants

Relates to https://github.com/nix-rust/nix/pull/377.  These constants
are only available in systems running the Linux kernel.

.  These constants
are only available in systems running the Linux kernel and are not
defined in musl libc (yet).

Add missing constants for wait family

Fixes #315

Use docker for all CI tests and images

Previously we were somewhat half-Docker, half-Travis, half apt-get, etc. This
commit alters the CI infrastructure to use Docker images for each target. This
should make it much easier to update the images and tweak various bits and
pieces of installed software. Additionally, it's also much clearer now what's
needed for each suite of tests!

Some images were updated a bit (e.g. musl is now 1.1.14), but other images
encountered failures when updating so they're not getting updated just yet.

Add Directory file descriptor relative syscall.

Add Directory file descriptor relative syscall.

I only added "*at" syscall relative to Posix2008 specification.

At the moment OSX and Android are partially supporting this API.

This include:
* `openat`
* `faccessat`
* `fchmodat`
* `fchownat`
* `fstatat`
* `linkat`
* `mkdirat`
* `mknodat` [0]
* `readlinkat`
* `renameat`
* `symlinkat`
* `unlinkat`
* `mkfifoat` [0][1]

[1] Not available on Android at the moment:
* `mkfifo`

[1] Not available on OSX at the moment:
* `mkfifoat`
* `mknodat`

And exclude operating system specific API:
* `renameat2`: Linux specific
* `execveat`: Linux specific since 3.19
* `futimesat`: GNU extension
* `name_to_handle_at`: GNU extension
* `scandirat`: GNU extension
* `fanotify_mark`: belong to fanotify API.

Fix semaphores on Solaris/Illumos

This adds `sem_t` structure introduced in https://github.com/rust-lang/libc/pull/309 and fixes compilation on Solaris.

Add more constants from sys/wait.h

And fix WIFEXITED on Linux, which seemed to be wrong.
