Handle 4 byte reads from the machine ID MMIO region. Also change the 6100

ae0bb838bf Add basic support for the extended ADB mouse protocol.
We now respond to the switch to device handler ID 4 and the register 1
read (as described by https://developer.apple.com/library/archive/technotes/hw/hw_01.html#Extended).

We don't yet use the extra precision bits in the register 0.

d08b486db0 Fix keyboard events occasionally being dropped
AdbKeyboard would copy the event into its own fields and set the
changed field, so that we could return the event when register was 0.
However, if a subsequent event was received before ADB polling, the
previous event would be overwritten and lost.

Fix this by maintaining a queue of events, so that we can return
everything since the last poll.

d45bba924d Fix "a" key always being as as a keyup
We were using an empty value on the second byte of the ADB keyboard
register 0, but that maps to the "a" key. This manifested itself
as the Key Caps DA never showing the "a" key as being down.

Switch to a non-existent key for the second byte.

d4c9db7fcf Move disk image reading to be behind an ImgFile class
Allows different implementations for different platforms (the JS
build relies on browser APIs to stream disk images over the network).

Setting aside the JS build, this also reduces some code duplication.

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.

35c86ad6bf Clean up #includes
Result of running IWYU (https://include-what-you-use.org/) and
applying most of the suggestions about unncessary includes and
forward declarations.

Was motivated by observing that <thread> was being included in
ppcopcodes.cpp even though it was unused (found while researching
the use of threads), but seems generally good to help with build
times and correctness.

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.
