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.

155b8cdad9 atahd: Support inexact CHS.
The total size needs to have 3 factors cylinders, heads, & sectors. Imagine a disk having a total size with 3 prime factors 3 x 5 x 11. 15 cannot be assigned to heads because that would only leave 11 for sectors and cylinders. Therefore, test all heads and sectors combinations. If the third factor for cylinders is not found, then choose 16 heads, then the minimum number of sectors, and finally the maximum number of cylinders. The loop could be changed to skip values of heads that are not a factor, but it doesn't take any time to try them all.

Workaround for the case when no hard disk image
was specified. The device instance is still there
but it won't be visible by the guest OS.

9d0bae2d03 atirage: Add offset to cursor X position.
CUR_HORZ_OFF becomes non-zero when the cursor needs to be drawn to the left of the left edge of the frame buffer.

CUR_VERT_OFF is handled differently. When CUR_VERT_OFF is non-zero, CUR_OFFSET is changed to point to the first line of the cursor that will be drawn, so CUR_VERT_OFF is the number of lines to remove from the total height of the cursor.
Alternatively, we could handle CUR_VERT_OFF the same way as CUR_HORZ_OFF by leaving the cursor height constant, drawing the cursor starting from the CUR_VERT_OFF line, and adjusting cursor Y position by negative CUR_VERT_OFF.

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.
