New Revision: 71637

URL: http://svn.reactos.org/svn/reactos?rev=71637&view=rev
Log:
Reworked message passing. Created struct TCP_CONTEXT. Moved lwip_tcp_pcb from ADDRESS_FILE
to TCP_CONTEXT. Successfully binding and handshaking between server and client, but
address destruction is still faulty and causes crashes.
