winedos / IRQ and mouse bug fixes

[Jukka Heinonen]

This patch fixes a number of minor bugs.
After this patch, X-COM (or UFO) seems to work
pretty well. However, it has problems switching
into combat mode, you get two cursors and DOS4GW 
still does not work...




Changelog:
    Real mode context should always have V86 flag turned on.
    Entering protected mode uses simpler and more robust
    virtual interrupt flag check.
    Mouse events are now received in graphics modes.
    Improved tracing output of int33 handler.
