extras: add rules for qemu guests
These patches enable usb autosuspend for the qemu emulated HID devices.
This reduces the cpu load for idle guests with a hid device attached
because the linux kernel will suspend the usb bus then and qemu can stop
running a 1000 Hz to emulate the (active) UHCI controller.

keymap: More robust state machine
Some drivers, like thinkpad_acpi, do not send a scan code at all (for known
keys), and some send the key code first, then the scan code. Implement a better
state machine which acceps them in any order and wait until a SYN event. If the
driver does not send SYN events, keymap will also handle this and print out
that fact.

Add ACL for media player USB devices
Originally we added an ACL for some particular mobile phone product IDs to
enable users to run e. g. the Android SDK as non-root. This was removed in 232f180 as we don't want to maintain product/vendor ID lists in udev.
However, we already know from media-player-info that devices like this are
media players. There is little reason to deny user access to those, so add back
a generic rule which adds an ACL to media player raw USB devices.

Use ata_id, not scsi_id, on ATAPI devices
The major benefit here, is that we get the ATAPI device serial
number. With SCSI ID we didn't get this since it's not part of the
SCSI INQUIRY command. Specifically this means that we get symlinks to
empty optical drives, e.g.
which we didn't get earlier. So this is a major win.
Also make ata_id work on CD-ROM devices when using /dev/bsg nodes so
this works on both the scsi_device as well as the block device. We do
this, basically, by issuing the ATA IDENTIFY PACKET DEVICE command
instead of the ATA IDENTIFY command. We also use 16-byte pass-through
ATA passthrough instead of 12-byte passthrough to avoid clashing with
the MMC BLANK command.

Run scsi_id and ata_id on the scsi_device object
In a multi-initiator setup, the HBA may very well export a SCSI device
for a device that another initiator has already logged into. But since
another initiator has already logged in, the kernel will not create a
block device.
Note that this is also the case for some RAID HBAs - for example, the
LSI 1068 series cards will export a SCSI device for a disk that is in
use by the HBAs RAID engine (no block device will be created here).
Running scsi_id and ata_id on the actual SCSI device means that we can
inquire the capabilities of the device. For example, we can check
whether ID_ATA_FEATURE_SET_SMART and ID_ATA_FEATURE_SET_SMART_ENABLED
is set and, if so, periodically poll the SMART status of the
disk. Even when other initiators has claimed the disk and if the disk
is in use by the RAID engine of the HBA.
Note that we run scsi_id and ata_id on /dev/bsg/* nodes - this is safe
to do because the scsi core guarantees that the bsg device has been
created before the actual add uevent for the scsi_device is emitted.
Since the block device is a direct child of the scsi_device we can
avoid running scsi_id and ata_id again by simply importing the
resulting ID_* properties from the parent.
needs to be reworked since we can't just use the CDROM_GET_CAPABILITY
ioctl on a /dev/bsg node (which is a character device). We do this by
just sending the SCSI INQUIRY command and checking the type (CD-ROM's
are all type 0x05 and disks are type 0x00) before we issue the ATA
IDENTIFY command through the SCSI command ATA PASS_THROUGH (12).
(Yes, it's a bit perverse how we have to tunnel our ATA commands
through a SCSI command but that's how Linux currently work.)
We still support for SG_IO version 3 (we fail back if version 4 fails
with EINVAL) because testing reveals that some drivers (such as
mpt2sas) still only support version 3 on the block nodes.
