ata: DMA requires a SG list

READCD can actually be requested so that no SG list is prepared.
Should help with #13775

* Wrote a new infoblock header according to ATA/ATAPI-6 that is cleaner and more
verbose than the old one. Removed the latter.
* Put some of the hardcoded values into defines for more clearity.
* Report more detailed device type for ATAPI devices and report removable
media based on the bit in the infoblock as well.
* Rename the channel ID attributes back to ide to let the hack in scsi_periph
work that then publishes the devices under the disk/ata[pi] tree.
* Also disable command queueing for ATAPI devices.
* Remove remnants of CHS support.

For packet devices we want to actually return a check condition when the device
indicates an error. Also we then need to pass through the request sense command
to the device. This should fix media status reporting for ATAPI.

Check the result after sending the packet, other error conditions like media
presence will be triggered there and we use FinishRequest() to catch those.

* Reworked device detection, we'll see how well this works...
* Reworked some of the transfer handling after reading the specs.
* Ensure that the device selection bit is set correctly for all commands.
* Generally disable interrupts and enable them only when expecting a DMA one.
* Renamed disk failure to device fault according to specs.

* Rework ATAPI handling, removing all PIO interrupts. As Marcus pointed out the
complication is not really worth it and it would in any case be unreliable
in the shared interrupt case (even though you could always check the poll
condition in the interrupt handler).
* Probably broke ATAPI with those changes though.
* Change blocksLeft to bytesLeft to allow using it for arbitrary ATAPI requests.
* Check some more error conditions and actually let those states get through
to the SCSI layer.

Adding ATAPI support to the new ATA bus_manager. Only tested in QEMU.

* Adding/updating license headers.
* Add the standalone ata module to the Jamfile.

* Work in progress commit of a reworked ATA bus_manager. It's now object based,
but doesn't really do anything more than before.
* It also replaces everything IDE with ATA counterparts and cleans up a lot
of the definitions.
* Cleaning up the old ATA bus_manager as well as some license headers missing.
