- Fix compilation of csrsrv:

- Fix compilation of csrsrv:
- helper.h does not exist anymore, so define what was used in srv.h instead
- Complete migration to PSEH2
- TEB's Cid was renamed to ClientId -- update the code
- Rename DllMain to DllMainCRTStartup as this is what we link a native dll to
- Fix some incorrect entries in the .spec
- Also fix some /W4 warnings. Add a note to CsrPopulateDosDevicesDirectory that the code is incomplete and will never stop looping (spotted by /W4).
- Does not link completely yet due to some missing function stubs.
