Propagate startupinfo to the child process (>= 4.3.14, Windows)

Description
With the hardening changes introduced with 4.3.14 it is not possible anymore to start a VM with the "hidden" window by executing virtualbox.exe --startvm with the SW_HIDE flag set in the STARTUPINFO data structure. It would be nice if this flag (and possibly other information) could be propagated to the child process created in "SUPR3HardenedMain-win.cpp". E.g., a fix like that:
@@ -1288,6 +1288,14 @@
SiEx.StartupInfo.hStdOutput = GetStdHandle(STD_OUTPUT_HANDLE); SiEx.StartupInfo.hStdError = GetStdHandle(STD_ERROR_HANDLE);
+ STARTUPINFOA si; + GetStartupInfoA(&si); + if (si.wShowWindow == SW_HIDE && (si.dwFlags & STARTF_USESHOWWINDOW)) + { + SiEx.StartupInfo.wShowWindow = SW_HIDE; + SiEx.StartupInfo.dwFlags = STARTF_USESHOWWINDOW; + } +
/*
- Set up security descriptors. */
This feature is nice, because it allows to hide the VM startup process from the user and only show the window when the VM is running. Alternatively, one could implement an option "start_minimized" or "start_hidden" controlled by vboxmanage.

Thanks for the report. I've addressed the issue, unfortunately it didn't make it in time for 4.3.16. So, I'm afraid you will have to wait for 4.3.18.
Sorry for the bad formatting.
