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.
Also update the includes.
It will allow to use those declarations globally where they are required (e. g. for SvchostPushServiceGlobals functions in some services).
No functional changes.
