osdep: add poll shim for macOS This implements a poll-compatible interface, backed by select on macOS, suitable for polling on device files - which are not supported by macOS's implementation of poll. This is a (long-standing) bug in macOS, so hopefully we can eventually remove this shim.

// Behaves like poll(3) but works for device files on macOS.
osdep: remove erroneous POLLERR emulation first of all, POLLERR is supposed to be ignored in `.events` and only returned in `.revents`. secondly select()'s exceptfds does not have a 1:1 correspondence with POLLERR. thankfully, the only caller of this function (in terminal-unix) never set the POLLERR flag so the errorfds were unused anyways. so go ahead and remove it entirely instead of pretending we can emulate something that's not possible.

// Only supports POLLIN and POLLOUT.
