sg1000.cpp: many improvements [Enik Land]
- Create a SG-1000 expansion slot.
- Hook up the SG-1000 expansion slot to sg1000.cpp and sms.cpp (sg1000m3).
- Split the sk1100 code from sg1000.cpp and attach it to the new expansion slot.
- Create a new FM Sound Unit device and attach it to the new expansion slot.
- For the sc3000 driver, re-add sk1100 as a fixed SG-1000 expansion device.
- Add sg1000 software list to sg1000m3 and Japanese/Korean SMS drivers.
sms.cpp: implemented some new findings [Enik Land]
- Remove some mirrors for ports $DC/$DD on SMSJ based on Charles' hw tests.
- Add basic C-Sync callback to 315_5124.cpp, based on Charles' hw tests.
- Add built-in Rapid Fire (uses C-Sync) for SMSJ and Korean SMS1 drivers.
- Add new SMS drivers due to XTAL differences:
sms1br - Tec Toy Master System I (Brazil)
sms2br - Tec Toy Master System II (Brazil)
smsbr - Tec Toy Master System III Compact (Brazil)
sms1paln - Tec Toy Master System I (PAL-N)
sms2paln - Tec Toy Master System II (PAL-N)
smspaln - Tec Toy Master System III Compact (PAL-N)
Brazil is PAL-M TV system, but I decided to call it by the
country name, seems to be better recognizable and for
emulation looks more like a NTSC system. PAL-N is used
in Argentina, Paraguay and Uruguay and looks closer to
the European PAL system when compared to PAL-M.
