ntdll: Fixed getting the RTS status from line, and now using sane default values for all (compilation/system) cases.

gdi32: Make GetICMProfile behave more like native. Rewrite ansi version as a wrapper and move color management functions to their own file.

ole32: Don't get the HRESULT from the buffer if we get an RPC_S_CALL_FAILED status back from the runtime.

The buffer might not contain any data and nowhere in our ole32 code 
passes HRESULTs in the buffer.

The operations peformed by the stubless code should roughly match what 
operations MIDL outputs in code, and it doesn't do this.

We're never going to implement the undocumented ones and we're moving 
more and more towards the architecture of the more recent versions of 
native rpcrt4.
