Following commit 24a727a23, give a lift to the SVCHOST global header
and add & complete all the missing definitions.
- Based on https://www.geoffchappell.com/studies/windows/win32/services/svchost/process/globaldata.htm
from public debug symbols (e.g. svchost, mswsock, w32time, wscsvc...),
adjust some of our symbols' names.
- Make the header C++-compatible.
- Even if the start/stop RPC server functions return an error code whose
underlying storage type is a 32-bit long, they don't return an RPC
status error code, but an NT status. Thus, use the adequate type
instead.
- The PSVCHOST_STOP_CALLBACK is nothing but a WAITORTIMERCALLBACK function.
- Take the opportunity to fix some of these functions' SAL annotations.
- Remark: "LP" for pointers is old-fashioned Windows, avoid this in NT code.
[MSWSOCK][SECLOGON] Do the minor adjustments. Remove unnecessary function casts.
