ppcmmu: Reduce unmapped physical memory logging.
...
Don't log consecutive accesses to unmapped physical memory addresses. This saves a couple hundred thousand lines in the log in some cases.
This is only a partial fix. Any access that isn't logged should be queued and output if a log message is output that is not this log message or after a time period.

Fix compiler warnings: uninitialized variables.
...
- mpc601_block_address_translation will now return 0 for prot and pa when bat_hit is false (when the if statement is not positive during the for loop). The calling function doesn't care what prot and pa are when bat_hit is false, but we do this to remove the compiler warining.
- For tlb_flush_entry, the compiler thinks m might not always be in the range 0 to 5 so tlb1 and tlb2 might not get initialized by the switch statement. Add default to get around this warning.

Fix compiler warnings: cast loses precision.
...
Use explicit cast when converting large integer types to smaller integer types when it is known that the most significant bytes are not required.
For pcidevice, check the ROM file size before casting to int. We'll allow expansion ROM sizes up to 4MB but usually they are 64K, sometimes 128K, rarely 256K.
for machinefactory, change the type to size_t so that it can correctly get the size of files that are larger than 4GB; it already checks the file size is 4MB before we need to cast to uint32_t.
For floppyimg, check the image size before casting to int. For raw images, only allow files up to 2MB. For DiskCopy42 images, it already checks the file size, so do the cast after that.

Fix TBR range
...
Fixed an issue where TBR doesn't have full 64-bit range. The original calculation was 64 bit and ended with a ÷ 10^9. This means the max for the upper 32 bits is 2^32/10^9 = 4. The solution is to use a multiplication method that supports a 96 bit product. core/mathutils.h contains functions for that. TBR driving frequency is assumed to be less than 1 GHz. Some minor modification is required for future > 1 GHz support.

Fix RTC units
...
Fixed an issue where get-msecs-601 and get-msecs-60x were not returning the same value. RTC was being calculated using timebase frequency instead of nanosecond frequency. 601 uses RTC. 60x uses TBR. On a real Mac, a G3 CPU won't have a RTC and accessing RTC would cause an exception. This is not the case for dingusppc but I don't think that's a problem.

Make accessing RTC or TBR not affect the other
...
Fixed an issue where the following would cause inconsistent results (tb in the left column would sometimes decrement instead of always incrementing):
2 0 do 2 0 do cr tb@ 8 u.r ." ." 8 u.r loop 2 0 do cr 12 spaces rtc@ 8 u.r ." ." 8 u.r loop 2 0 do cr tb@ 8 u.r ." ." 8 u.r space rtc@ 8 u.r ." ." 8 u.r loop loop
RTC and TBR could not be used simultaneously because they are both incremented by an amount based on the last time stamp but that time stamp can be changed by accessing either RTC or TBR. The solution is to have a different time stamp for each.
