Removed the file pointer from the hdd_t struct;

Partially split off the Logitech Serial Mouse emulation from Microsoft Serial Mouse;
Slightly reworked serial port emulation (the two UART's are now device_t's, non-FIFO mode implemented and is now default, FIFO mode reimplemented from scratch so it's now actually correct);
Added the emulation of the SiS 85c497 chip to the SiS 85c496/497 chipset;
Bugfixes to the emulated Super I/O chips and made them all device_t's now.
