917eec6ff4 CMakeLists.txt: Fix testppc copy command. 
The destination of the .csv files should be that of the testppc
executable, not the dingusppc executable.

On Apple platform, the dingusppc executable may be a bundle and copying
the .csv files into the bundle causes a code signing error.

ad4515721b amic: Emulate SCC receive DMA registers instead of returning random values. 
The SCC DMA Receive control registers previously returned std::rand(),
a workaround to unblock Mac OS 8.5/8.5.1 boot which polls these
registers expecting specific bit patterns. This caused non-deterministic
bimodal boot times (~10s vs ~18s) on Power Mac 6100 as the guest would
sometimes enter a ~7s polling loop depending on the random value.

Add AmicSerialRcvDma to properly track the control register and byte
count state for both SCC receive channels. Writes now update the status
byte using the same bit manipulation as the transmit DMA channels, and
reads return the tracked state. Also wire up the RX byte count registers
(SCC_RXA/B_Byte_Cnt_Hi/Lo) which were previously ignored on write.

b182e01218 viacuda: Avoid float in VIA timer calculations. 
- float is limited to 24 bits so use longer uint32_t or uint64_t.
- Rename the formal parameter so it more closely matches the actual
  parameter. Also, don't hide the class field.
- Multiply is faster than divide.
