well. Stop all threads (one per TCP stream and UDP connection) and free

kvm tools: Respect guest tcp window size

Respect guest tcp window size and stop sending tcp segments to guest
if guest's receive window is closed.

This fixes the TCP hang I'm seeing where guest and host are transferring
big chuck of data.

This problem was not triggered when guest and external host
communicates, probably because guest to external host communication
walks through real network and is much slower than guest and host
communication. Thus, guest's receive window has little chance to be
closed.

kvm tools: Make tcp between guest/host virtual ip work in UIP mode

This pach makes tcp between 'guest ip' and 'host virtual ip' work in UIP mode.
(The defulat guest ip is 192.168.33.15, host virtual ip is 192.168.33.1)

guest$ wget http://192.168.33.1/file
guest$ ssh 192.168.33.1

Without this patch, user has to figure out the ip address of host's
interface (e.g. eth0) and use that ip address to access host.

With this patch, user can simply use the virtual host ip.
