[NTVDM][KERNEL32]
In DosCreateProcess, allocate space for the environment block dynamically and expand
it if needed, just like we do in CommandThreadProc.
In GetNextVDMCommand, remove the check that checks whether VDMState is one of
VDM_NOT_LOADED, VDM_NOT_READY or VDM_READY - that check makes no sense whatsoever,
since those aren't input values for that structure field. Their bit masks do correspond
to valid input fields, but even then the check makes no sense.
