3b29783dc8 os: define SOCK_CLOEXEC on Linux
If it's not already defined, and we are on Linux, #define it. This gets
rid of a load of #ifdefs. This should also allow to use it when the
kernel supports it, but the libc does not define it.

1f827a4776 os: remove unneeded errno assignment
If socket() fails, it will return failure code. No need to reset errno
beforehand.

7134a439c1 os: wrap socket(SOCK_CLOEXEC) calls
Some system C libraries do not offer SOCK_CLOEXEC flag.

Add a new header for OS compatibility wrappers. Wrap socket() calls into
wl_os_socket_cloexec() which makes sure the O_CLOEXEC flag gets set on
the file descriptor.

On systems having SOCK_CLOEXEC this uses the old socket() call, and
falls back if it fails due to the flag (kernel not supporting it).

wayland-os.h is private and not exported.

Add close-on-exec tests for both normal and forced fallback paths.
