If connect_unsecure failed due to protocol version mismatch, don't try to
connect_secure with the same version, but retry (connect_secure or
connect_unsecure) with older version. catch (...) is handled by caller
at RedChannel::run().
This solves the following bug: when "new" Spice client (protocol version 2)
with given secure_port connects to "old" server which is not using the same
secure_port (or not using a secure_port at all), the client exits immediately.
In this scenario, the client first tries to use Spice protocol version 2 to
connect the unsecure port, and altough this fails due to version mismatch, it
tries to connect to the secure port with the same protocol version 2, which is
a wrong behavior, fails due to socket error 10061 (WSAECONNREFUSED -
Connection refused) and handled mistakenly by immediate exit, instead of
retrying with protocol version 1.
We erronously ignored data from guest on the serial channel if no client is
connected. This leads to an assert when the guest writes a second time, since
there is still data unconsumed by us (the host).
Fix by reading data anyway, and discarding it after parsing (and reading) whole
messages from the guest.
Net affect is that any messages the agent sends while no client is connected
get discarded, but only full messages are discarded.
This fixes an abort if booting a winxp guest with vdagent without a connected
client.

Currently when going / starting fullscreen if the guest resolution for one of
the monitors is higher then that monitor on the client can handle, we show a
white screen. Leaving the user stuck (unless they know the fullscreen key
switch combi) with a white screen when starting the client fullscreen from
the XPI.
This patch changes the client to fall back to windowed mode in this case
instead.
