Alexandre Julliard 9caa71eef4 Redesign of the server communication protocol to allow arbitrary sized
data to be exchanged.
Split request and reply structures to make backwards compatibility
easier.
Moved many console functions to dlls/kernel, added code page support,
changed a few requests to behave properly with the new protocol.
