Make io_select return errors
instead of returning 0 and make clients have to actually read the error.
This makes implementing "poll" much easier.
Based on Svante Signell's patch.
* pflocal/io.c (S_io_select): Return error returned by pipe_wait_readable or
pipe_wait_writable.
* trans/fifo.c (trivfs_S_io_select): Return error returned by
pipe_wait_readable or pipe_wait_writable. Return EBADF on bogus access mode.
* trans/new-fifo.c (trivfs_S_io_select): Likewise.
