Do a much simpler initialization instead:
* The "Get ID" command was used for detecting whether a mouse is present.
But it just handled normal mice, IntelliMice and IntelliMice Explorer, although there can be many more possible values for other mice. (see for example http://www.win.tue.nl/~aeb/linux/kbd/scancodes-13.html#mcf2).
Also this command isn't available on all systems.
Furthermore we already do a MOUSE_LINE_TEST in i8042BasicDetect, which is the more reliable method to test whether a mouse is plugged in. Therefore this "Get ID" command can be simply removed.
* The whole mouse initialization process now boils down to enabling the mouse itself and in the controller
* All in all, some more mice should be detected now.
- Give i8042IsrWritePort a boolean return value and pass the results of the i8042Write calls
- Replace two i8042Write calls for writing to the mouse by one i8042IsrWritePort call where possible
- Remove the unused KBD_LINE_TEST define
This change was tested under QEMU, VMware and on one real system.
