- Split terminal emulation code from the main part of the driver so that we can have alternative terminal emulator modules if we like in the future. (We are not quite there yet, though.) - Put sysmouse related code in a separate file, thus, simplifying the main part of the driver. As some files are added to the source tree, you need to run config(8) before you compile a new kernel next time. You shouldn't see any functional change by this commit; this is only internal code reorganization.
