Add detailed AC_ERR_* flags and use them. Long-term goal is to describe all errors with err_mask and tf combination (tf for failed sector information, etc...). After proper error diagnosis is implemented, sense data should also be generated from err_mask instead of directly from hardware tf registers as it is currently.

ATA devices don't generate many errors, so the preferred method is to printk() when they occur. ATAPI devices generate tons of exceptions during the normal course of operation, so this change skips logging the most common class of errors.

- Fix a regression in command completion, which prevented the restart of the DMA engine after the device throws an error. - Pack more hardware info into the port-reset error message. - Promote "welcome to our timeout" message from debug msg to normal printk.

Needed to get ATAPI working. - dump hardware error bits, if hardware signals an error - only reset hardware during timeout if a command was active - call ata_qc_complete() with a fine-grained error mask. Needed so that atapi_qc_complete() can distinguish between device errors and other errors.

Although according to the documentation this largely only affects desktop LED control, let's make sure we set the ATAPI bit when we have an ATAPI device attached to the port.

Don't directly reference qc->n_elem, as that might cause an off-by-one error for misaligned (padded) ATAPI transfers.

Use ata_pad_{alloc,free} in two drivers, to factor out common code. Add ata_pad_{alloc,free} to two other drivers, which needed the padding but had not been updated.

A few drivers were not following the standard meme of printing out their driver name and version at module load time; this is fixed as well.

The second argument to ata_qc_complete() was being used for two purposes: communicate the ATA Status register to the completion function, and indicate an error. On legacy PCI IDE hardware, the latter is often implicit in the former. On more modern hardware, the driver often completely emulated a Status register value, passing ATA_ERR as an indication that something went wrong. Now that previous code changes have eliminated the need to use drv_stat arg to communicate the ATA Status register value, we can convert it to a mask of possible error classes. This will lead to more flexible error handling in the future.

Enforce access rules where appropriate. If the compiler is smart enough, this may buy us an optimization or two as a side effect.

ata_get_mode_mask() uses bits 3 and 4 in the pio_mask to represent PIO modes 3 and 4. The value read from the drive, which reports support for PIO3 and PIO4 in bits 0 and 1, is shifted left by 3 bits and OR'd with 0x7 (which then corresponds to PIO 2-0 in libata). Thus, the drivers below need adjustments to comply with the way pio_mask is used. I changed the masks from the commented values to all support PIO4-0, since the spec mandates that PIO0-2 are supported and there's no reason not to support PIO3 IMO.
