[XDK]: Do not always redefine the ASSERT(MSG) macros with the NT_xxx ones, especially for the FreeLdr/... bootloader (where we don't use WinDbg for debugging, yet), because in this case the int 0x2c is hardly informative. We fall back to the good old RtlAssert which displays an assertion failure string in the default debug output port (e.g. serial), and then does an int 0x03.

[FREELDR]
- "static"-ify some printing helper functions;
- hide the textmode cursor before blue-screening;
- disable interrupts before hanging forever.
