Implement the CSR NtConnectPort startup handshake so Windows guests can connect to \Windows\ApiPort, receive CSR connection data, and map their client section.

CSR client and CSRSS bases currently alias one mapping; distinct virtual mappings over shared backing remain TODO. Also, only BASESRV static-data slot 1 is populated; CSRSRV (0), CONSRV (2), USERSRV (3) remain TODO.

Implement the CSR NtConnectPort startup handshake so Windows guests can connect to \Windows\ApiPort, receive CSR connection data, and map their client section.
CSR client and CSRSS bases currently alias one mapping; distinct virtual mappings over shared backing remain TODO. Also, only BASESRV static-data slot 1 is populated; CSRSRV (0), CONSRV (2), USERSRV (3) remain TODO.
