More CreateProcess work.
This series mainly:
- tests and implement fixes for GetStartupInfoW:
- it should transform PEB's RTL_USER_PROCESS_PARAMETERS on the fly (instead of caching the results as GetStartupInfoA)
- it doesn't set all the fields of returned in STARTUPINFOW (unlike GetStartupInfoA)
- no longer allow console and console handles for non CUI apps:
- forbid inheritance of console handles for non CUI apps
- don't create a unix console for initial (non CUI) app
