on the correct address space. Added DOSMEM_MovePointers() that relocates selectors when the DOS address space changes (i.e. when dosmod is spawned, particularly from Win16 apps that uses DPMI to execute real-mode code). More complete DOS device implementation.

/* NOTE: Interrupts might get called from three modes: real mode, 16-bit, and

* parameters, interrupt handlers should use CTX_SEG_OFF_TO_LIN with

* the contents of a segement register as second and the contents of
|
|
* a *32-bit* general register as third parameter, e.g.

|
|
* Real-Mode: Seg*16 + LOWORD(Offset) + V86BASE
|
|
* 16-bit: convert (Seg, LOWORD(Offset)) to linear
|
|
* 32-bit: use Offset as linear address (DeviceIoControl!)
|
|
*
|
|
* Real-mode is recognized by checking the V86 bit in the flags register,
|
|
* 32-bit mode is recognized by checking whether 'seg' is a system selector
|
|
* (0 counts also as 32-bit segment).
