Always null-terminate ccb_pathinq.(sim_vid|hba_vid|dev_name)

The sim_vid, hba_vid, and dev_name fields of struct ccb_pathinq are
fixed-length strings. AFAICT the only place they're read is in
sbin/camcontrol/camcontrol.c, which assumes they'll be null-terminated.
However, the kernel doesn't null-terminate them. A bunch of copy-pasted code
uses strncpy to write them, and doesn't guarantee null-termination. For at
least 4 drivers (mpr, mps, ciss, and hyperv), the hba_vid field actually
overflows. You can see the result by doing "camcontrol negotiate da0 -v".

This change null-terminates those fields everywhere they're set in the
kernel. It also shortens a few strings to ensure they'll fit within the
16-character field.

MFC r295276: Add defines for WRITE_UNCORRECTABLE ATA command, and improve

2016-03-06T02:33:02+00:00

command logging

Add #defines for ATA_WRITE_UNCORRECTABLE48 and its features. Update the
decoding in ATACAM to recognize the new values. Also improve command
decoding for a few other commands (SMART, NOP, SET_FEATURES). Bring the
decoding in ata(4) up to parity with ATACAM.

On my own tests I see no effect from this change, but I also can't
reproduce the reported problem in general.

MFC r286814, r286816: Remove UMA allocation of ATA requests.

2015-08-29T10:52:16+00:00

After CAM replaced old ATA stack, this driver processes no more then one
request at a time per channel.  Using UMA after that is overkill, so
replace it with simple preallocation of one request per channel.

MFC r286448: Disable 32-bit PIO for 6Gbit/s Intel SATA controllers.

2015-08-22T07:45:49+00:00

For some reason 32-bit PIO writes are not working on 6Gbit/s Intel SATA
ports, while 16/32-bit PIO reads and 16-bit PIO writes are working fine.
3Gbit/s ports on the same controllers have no this problem.

Workaround this by disabling 32-bit PIO for all Intel controllers that may
have 6Gbit/s ports.  It halves PIO performance from 6MB/s to 3MB/s, but
who bother about speed of such rare and slow mode, which is also highly
discouraged by SATA specifications?

Remove from legacy ata(4) driver support for hardware, supported by newer
and more functional drivers ahci(4), siis(4) and mvs(4).

This removes about 3400 lines of code, unused since FreeBSD 9.0 release.

MFC r280393: Reduce priority of ATA/SATA drivers.

Legacy ata(4) -> BUS_PROBE_LOW_PRIORITY;  more functional ahci(4), siis(4),
mvs(4) -> BUS_PROBE_DEFAULT;  BUS_PROBE_VENDOR leave for vendor drivers.
