David Herrmann 9fdda3b09a wpas: drain input-queues before signalling HUP 
We _must_ aggressively drain input queues before we signal any HUP. There
might be queued messages that tell us important information about the
termination of wpa_supplicant.

Therefore, if a write() operation fails, we only signal HUP if the input
queues are empty. However, we cannot rely on EPOLLIN to be set, as the
input data might have arrived in between epoll_wait() and write(),
therefore, always run the non-blocking read() in case write() failed.

= MiracleCast - Wifi-Display/Miracast Implementation =

The MiracleCast project provides software to connect external monitors to your
system via Wifi. It is compatible to the Wifi-Display specification also known
as Miracast. MiracleCast implements the Display-Source as well as Display-Sink
side.

The Display-Source side allows you to connect external displays to your system
and stream local content to the device. A lot of effort is put into making this
as easy as connecting external displays via HDMI.
On the other hand, the Display-Sink side allows you to create wifi-capable
external displays yourself. You can use it on your embedded devices or even on
full desktops to allow other systems to use your device as external display.

== Requirements ==

  The MiracleCast projects requires the following software to be installed:
    - libwfd: A stand-alone library implementing the Wifi-Display protocol.
              http://www.freedesktop.org/wiki/Software/miracle/libwfd
      required: >=libwfd-1

    - systemd: A system management daemon. It is used for device-management
               (udev), dbus management (sd-bus) and service management.
      required: >=systemd-209

    - glib: A utility library. Used by the current DHCP implementation. Will
            be removed once sd-dns gains DHCP-server capabilities.
      required: ~=glib2-2.38 (might work with older releases, untested..)

    - check: Test-suite for C programs. Used for optional tests of the
             MiracleCast code base.
      optional: ~=check-0.9.11 (might work with older releases, untested..)

  Note that systemd-209 is not released, yet. However, several unreleased
  interfaces of it are used. Please see the MiracleCast website for hints how
  you can use it right now.
