copy some files from wayland

Let's not reinvent the wheel and reuse the files from wayland.
At least for now, we can get rid of them later.

Copied:
    wayland-os.c
    wayland-os.h
    wayland-util.c
    wayland-util.h
    connection.c
    wayland-private.h

from revision e2c0d47b0c77f18cd90e9c6eabb358c4d89681c8
fix init autotools
strip wayland files of unneeded functions

These function we don't need and they bring ffi dependency
to this program, therefore remove them.
wayland: connection, add wl_connection_copy_fds function

this function pipes filedescriptors from one connection to another
(from input buffer to output buffer).
