[poky] [PATCH 1/4] bitbake/uievent: fix queueing of events for xmlrpc before UI has loaded

[Joshua Lock]

The recent change to Queue up events before the UI is spawned (in
26eda933379801ef1c8b4b09e67d14f498cd3813) broke the xmlrpc server because the
uievent implementation of BBUIEventQueue expects pickled strings for its
queue_event() method.

This is because the RPC exposed event.send() method must accept pickled
strings, but for xmlrpc event.send() is just mapped to queue_event().

Work around this by adding a send_event method which unpickles strings and
hands them off to queue_event() which can then be used for the remapping.
