Creates a GLib.Source that's dispatched when condition is met for the
given channel. For example, if condition is GLib.IOCondition.IN, the source will
be dispatched when there's data available for reading.
g_io_add_watch() is a simpler interface to this same functionality, for
the case where you want to add the source to the default main loop context
at the default priority.
On Windows, polling a GLib.Source created to watch a channel for a socket
puts the socket in non-blocking mode. This is a side-effect of the
implementation and unavoidable.
