We had a case on Windows 2012R2 where any early resizes would be
handled by a reconnect rather than an online resize, which led to a
bunch of follow-up problems with the session startup.
To solve this, we gave the RDPEDISP channel more time to become
established.

Resize session using disconnect/reconnect sequence should not be
performed before we have received an auto-reconnect cookie which is
used for reconnecting to the session. There is a race when trying to
reconnect at this point so a defer timer is used to delay this further
from the point where the auto-reconnect cookie is received.
Fixes a problem where a login prompt is shown upon reconnect even if
the auto-reconnect cookie is available and used.

This adds support for resizing the RDP session dynamically based on
the window size. Some complicated logic has been added to avoid
sending excessive amounts of resize requests to the RDP server.
When supported, this resize mechanism should use the RDPEDISP way of
signalling the server to initiate a Deactivate/Activate sequence, but
rdesktop will fall back on Disconnect/Reconnect if RDPEDISP is not
supported by the server.
ui_select has been refactored and most functionality has been broken
out into three new functions, simplifying ui_select into a loop.
