Modified Files:
        src/sys/arch/x68k/dev: ms.c

Log Message:
Remove dumb middle button emulation code from the ms(4) driver.

Also fix leftover comments (derived from the original Sun's "firm_event"
implementation as seen in sys/dev/sun/ms.c) to sync with reality on x68k.

The current implementation the ms(4) driver just checks whether
two (left/right) buttons are changed in the same packet.
This means it cannot handle a release event correctly if two
buttons pressed simultaneously are released in the different timing.

The middle button emulation should be handled in application layer
as other Xservers do, and I'll import Emulate3Buttons support for the
X68k Xorg based monolithic server.
