* Major state refactoring of pc98 based HW (#8475) Angelo Salese2021-08-241-0/+140
First major step in splitting up machine classes in NEC PC98 family tree: * Splits up derivative HWs into own state machine and files (pc98ha.cpp, pc9821.cpp and pc9801_epson.cpp); * Adds a preliminary uPD4991a parallel RTC, used by pc98ha; * Fix -26, -86, -118 C-bus sound board dips or jumper settings; * Fix default sound card for pc9821 (-86) and pc9821ce2 / pc9821cx3 (-118); * Adds preliminary MAD Factory Otomichan-kai C-bus sound board; * Adds boilerplate code for C-bus installing board I/Os, avoiding the possible inconvenience of board(s) getting silently unmapped by other installed boards; * Major refactoring of HW dip switches readouts, using required_ioports instead of scattering things around in PPI hooks; * Extensive QA rundown, including research on missing features and undumped machines. pc9801.cpp: Don't passthrough mouse irq frequency when cycle setting is setup too, fixes jastrike mouse input on options menu. pc9801.cpp: Fix kanji RAM window LR readback, makes telenetm to properly display 8x16 chars on RS and derivative machines. pc8801.cpp: fixed OPNA RAM readback, allowing SWs to playback ADPCMs properly.
