T80/8080 Mode (Mode 2) CPU Fixes:
1. ALU-based subtractions have AC flag inverted, SUB/SBB/DCR...
2. RRC/RLC/RAL/RAR only modify C flag
3. STC/CMC/CMA do not change AC flag
4. ALU AND operation sets AC flag to (BusA(3)|BusB(3))
5. DAD instruction does not modify AC flag
6. RESET does not change Flags, SP and Accumulator, only PC is set to zero

The fixes above make this core pass all known 8080 CPU tests.
Results of 8080 Executioner match those of real CPU, tested on Vector-06c with
KR580VM80A.

Audio clocks are generated by another PLL for the time being: tape loading
didn't work otherwise.
