Socket sample:

- Test 3 added to test large transfers involving multiple low level calls.
- Stub for datagram socket tests (not yet in place)

IPC sample:
- Client no longer needs to use GetHostName for DDE and LocalHost for IPC;
now it can just use GetHostName for both (because now the IPC server binds to
INADDR_ANY instead of binding to localhost).
- Fixed once again another warning about wxString objects that can't be
passed through '...'
