- Use the new messaging structures and the new macros, plus the new CSR_API function's signature (--> and rename some variables).
- Code cleaning & formatting.

[CSRSS/NDK]
- Reorganize all the header files in logical units (server.h for server-side of CSR, client.h for client-side, and msg.h for messaging), removing duplicated definitions.
- Code cleaning & formatting.

The next step would be to activate the code of server-dll loading inside csrsrv, then moving all the console-related APIs from win32csr to winsrv, the latter built with the same structure as csrsrv's.
