Log:
[KD]
- When enabling or disabling the kernel debugger and setting the KdDebuggerEnabled flag,
also update the corresponding user-mode flag in SharedUserData->KdDebuggerEnabled.
- Turn KdpGetMemorySizeInMBs into a INIT_FUNCTION.
- Print kernel command line & ARC paths even in debug log file mode.
[KD64]
WinKD: Also print our nice ReactOS debug header (version, # of processors & memory MB,
kernel command line and ARC paths).
