c999c51d77 scsicdrom, scsihd: Check lun. 
READ_CAPACITY_10, READ_6, and READ_10 now checks LUN that is included in CDB and returns a CHECK_CONDITION if it doesn't match.

d3c913e384 scsicdrom: Cleanup. 
- Use macros for reading 2 byte or 4 byte big endian data. block_size is assumed to be < 64K so WRITE_DWORD_BE_A will write two leading zeros.
- Scalar pass by value parameters don't need to be const.
- Remove some unnecessary locals.

a79f07e4dc scsicdrom: Move mode_select_6. 
Make it a separate method like scsihd. It also checks the incoming param size. If it's zero then the phase is not switched. Is that wrong? Still probably unfinished.

fd961f9ff9 Fix Analyzer warnings. 
In Xcode, type Command-Shift-B to analyze every source file or Command-Shift-Control-B to analyze the current source file.

For pseudo_dma_read report FIFO underrun and init data_word in that case.

45a9d45e3f Add SCSI devices. 
scsibus has a new method attach_scsi_devices which is used by all machines to populate a SCSI bus with one or more hard drives or CD-ROM drives.

HDDs are specified by the hdd_img property.
CDs are specified by the cdr_img property.
Multiple images are delimited by a colon :

attach_scsi_devices is called by the scsi controller after the scsi controller has attached itself to the scsi bus.
The bus suffix is applied to the property name.
Curio has no suffix so it will use hdd_img and cdr_img properties.
Mesh is expected to have a suffix of 2 so it will use hdd_img2 and cdr_img2 properties.

HDDs will skip SCSI ID 3 unless 7 HDDs are added, in which case, the seventh HDD will use ID 3.
CDs will start at SCSI ID 3, go to 7, then down to 0.
SCSI IDs are skipped if a device is already using that SCSI ID.

ScsiCdrom and ScsiHD no longer use REGISTER_DEVICE or DeviceDescription or PropMap which is normal for devices that can have multiple instances.
