Subject: [PATCH] use POSIX poll.h instead of sys/poll.h
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

POSIX specifies that <poll.h> is the correct header to
include for poll()
  http://pubs.opengroup.org/onlinepubs/009695399/functions/poll.html
whereas <sys/poll.h> is only needed for ancient glibc (<2.3),
so let's follow POSIX instead.

As a side-effect, this silences numerous compilation warnings
when compiling against the musl C-library:
