This might fail even under correct usage, e.g. if read_control() is called
from another thread before write_control() finished in another. It has to be
retried then, or other measures have to be taken, depending on how it is used
by the surrounding code.

Add a special timer mode in GstPoll that makes it only use the control socket
with a timeout to schedule timeouts. Also add a pair of methods to wakeup the
timeout thread.
API: GstPoll::gst_poll_new_timer()
API: GstPoll::gst_poll_write_control()
API: GstPoll::gst_poll_read_control()

Remove GstPollMode from the API, it does not make sense to let the
application control this.
Add support for Win32.
Fix the testsuite. Fixes#520671.

Added Since tags.

* gst/gstpoll.h:
Add generic poll abstraction. We ideally don't want to have this in core
here but in glib intead...
This code will be used in various network elements and ultimately for
the nanosecond precision monotonic clock (that's why it's here in core).
It'll allow us to implement cancelable socket operations for windows too.
