server: Separate console and new group flag (CreateProcess).
We were using bit 1 of RTL_USER_PROCESS_PARAMETERS for two different cases: - rightfully, as a sign to block ctrl-c events from being processed by handlers (and by default, terminating the process) - But this was also used to request for the creation of a new process group.
This patch properly separates the two use cases, by using the ProcessGroupId field in RTL_USER_PROCESS_PARAMETERS (checked that Win10 behaves as this patch in RtlCreateUserProcess wrt. RTL_USER_PROCESS_PARAMETERS ProcessGroupId usage input/output).
Introduce process_group_id in startup_info_t and use it to pass it to server. ProcessGroupId field in RTL_USER_PROCESS_PARAMETERS is now properly set.
Note: this will change some external behavior. - before this patch, a child process created with Ctrl-C disabled (ConsoleFlags set), couldn't turn it on as the process was detached from unix console. - now, SIGINT handling is moved to kernelbase (and can be turned on/off at application will), - when creating a new windows group id, the child will be detached from unix console, so will no longer receives the SIGINT from ctrl-c in unix console (if parent was attached to this unix console).
