#12419: use POSIX poll.h instead of glibc-specific sys/poll.h
------------------------------+----------------------------
 Reporter:  git@…             |      Owner:  chris_kohlhoff
     Type:  Patches           |     Status:  new
Milestone:  To Be Determined  |  Component:  asio
  Version:  Boost 1.61.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+----------------------------
 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 a warnings when compiling
     against the musl C-library:

     In file included from ./boost/asio/detail/socket_types.hpp:61:0,
                      from ./boost/asio/ip/address_v4.hpp:21,
                      from ./boost/asio/ip/address.hpp:21,
                      from libs/log/src/init_from_settings.cpp:65:
     <sysroot>/usr/include/sys/poll.h:1:2: warning: #warning redirecting
 incorrect #include <sys/poll.h> to <poll.h> [-Wcpp]
      #warning redirecting incorrect #include <sys/poll.h> to <poll.h>
       ^~~~~~~

     etc.
