5a5ae9fd16 Exit with a non-0 exit code if there are errors
More correct behavior (and makes the Infinite Mac wrapper not close
the emulated Mac, which it does when it thinks there was a graceful
shutdown).

73272b28dd Implement the ADB keyboard
Besides generating KeyboardEvents in the SDL event handler and
returning the key state in the register 0 reads of the AdbKeyboard
device, we also needed to generalize the ADB bus polling a bit. We now
check all devices that have the service request bit set, instead of
hardcoding the mouse.

The SDL key event -> ADB raw key code mapping is based on BasiliskII/
SheepShaver's, but cleaned up a bit.

47d2e235a3 atirage: prevent big-endian accesses outside VRAM.
The simplest solution is to cut the aperture size by the amount
of video RAM installed. This way, accesses to the big-endian
aperture located above the installed VRAM will be catched and
reported by the MMU.

acdb14a10a Recalculate execution block after RFI.
While booting Mac OS X 10.2 installer CD, a return from RFI didn't change the instruction address virtual memory page but did change the physical memory page so we must always recalculate the physical address after RFI.
Perhaps there are other cases where this may be required?

dcd4384d46 Fix eb_end calculation.
- Subtract one so that it can't overflow to zero.
- Use page_start as the base so mask operation is not required.
- Recalculate it only when the page changes.

8348370142 Add separate flags for instruction and data TLBs.
The same flag was being used for flushing both instruction and data TLBs so sometimes a flush for one TLB list would not occur if the flag was cleared when flushing the other TLB list.

6b3cdad877 ppcmmu: Fix BAT update.
Need to schedule flush of both BAT and PAT type TLBs because BAT takes precedence over PAT which means updating a BAT can invalidate a PAT.

637844269f atapicdrom: Implement sector areas for Read CD.
The disk cache is unchanged. data_ptr continues to be only used for the user data sector area for each block. The other sector areas (synch, header, etc.) are filled in while reading.

has_data and get_data exist as a way to bypass data_ptr for parts of the transfer outside the user data sector area of each block. The default behaviour is defined in atabasedevice and is overridden by atapicdrom for the Read CD command. atapicdrom has a flag doing_sector_areas to control the behavior of the get_data method. When the flag is true, the sector_areas, current_block, and current_block_byte are used for selecting the correct data from one of the sector areas. The Read CD command initializes those variables. xfer_cnt remains the total number of bytes to be transferred and is now not necessarily the same as the number of disk image blocks read into the disk cache.

lba_to_msf is used to fill in the header. The values was not verified using a real CD.

Mac OS X just cares about the Mode in the header. For now, only the synch and header and user data areas are filled in. The other areas read as all zeros.

4bbc5ab0af CD-ROM: Fix interpretation of session number.
In Read TOC format 2, Mac OS X passes zero for Session Number. I believe Read TOC is supposed to return the first session starting from that number so it should return info for Session 1 as it would if Mac OS X passed 1 for the Session Number.
