59315b183d [kernel] Fix reading from empty board buffer (sf63.2)
Syscall 63.2, reading from the board buffer, was overwriting registers
edx and ebp when the buffer was empty. Now it sets eax and ebx according
to the kernel API.

Because of this ancient bug BOARD checks the status of sf63.2 syscall
this way:
        mcall   63, 2
        cmp     ebx, 1
        jne     no_data
        ; when the buffer is empty, ebx is untouched, i.e. still 2, haha
        ; edx and ebp are destroyed, the code is lucky not to use them

By the way, the bug was found using umka tool.

83176ac8ef kernel: Fix window redraw after 1px move.
If
 - window A is above window B, and
 - window A has been moved,
then window B receives a redraw event.

But if that move was 1px right or down, window B didn't receive an event
because of off-by-one error. Now it's fixed.
