This commit was manufactured to restore the state of the 5.3-RELEASE image.

atapicam(4) is currently off by three orders of magnitude regarding the

2004-06-17T07:29:56+00:00

timeout values in the CAM CCBs.  Divide by 1000 to get values in seconds
which are what ata(4) timeouts internally use.

This does lose granularity, though, and small values can now round down
to zero.  It's probably worth making all ata(4) timeouts in terms of
hz/ticks/milliseconds/something.

Use auto-sense data provided by the lowlevel ATA code.

(atapi_cb): Reenable automatic retrieve of sense data on error, making

2004-02-11T10:14:08+00:00

 it asynchronous to avoid incorrect use of ata_atapicmd within an
 ATAPI callback.

Fixed a memory leak.

Use UMA instead of plain malloc for getting ATA request storage.

This gives +10% performance on simple tests, so definitly worth it.
A few percent more could be had by not using M_ZERO'd alloc's, but
we then need to clear fields all over the place to be safe, and
that was deemed not worth the trouble (and it makes life dangerous).

#include sema.h is now required.
