dc0ff2140b Fix a number of bugs and significantly alter the command execution path to
properly support bounce buffers and resource shortages.  This allows the
driver to work properly and reliably with more than 4GB of RAM.  Of the
three data paths that exist in the driver, (block, CAM, ioctl), the ioctl
path has not been well tested with these changes due to difficulty with
finding an application that uses it that actually works.

2813692cc2 Merge common XPT_CALC_GEOMETRY functions into a single convenience function.
Devices below may experience a change in geometry.

* Due to a bug, aic(4) never used extended geometry.  Changes all drives
  >1G to now use extended translation.
* sbp(4) drives exactly 1 GB in size now no longer use extended geometry.
* umass(4) drives exactly 1 GB in size now no longer use extended geometry.

For all other controllers in this commit, this should be a no-op.

891619a66d Use bioq_flush() to drain a bio queue with a specific error code.
Retain the mistake of not updating the devstat API for now.

Spell bioq_disksort() consistently with the remaining bioq_*().

#include <geom/geom_disk.h> where this is more appropriate.

60794e0478 Centralize the devstat handling for all GEOM disk device drivers
in geom_disk.c.

As a side effect this makes a lot of #include <sys/devicestat.h>
lines not needed and some biofinish() calls can be reduced to
biodone() again.

d6b32def6c (1) Problem: PANIC when loading/unloading driver
as module. This also fix's issue kern/45713.
Fix - polling was implemented incorrectly for
adapter enquiry and adapter flush.
(2) Problem: PANIC when unloading driver
as module.
Fix - device nodes are not destroyed for amr0,
and amrd* when driver is unloaded
(3) Problem: PANIC from loading driver when
3ware adapter present, error message "Warning
"amrd is usurping twed's bmaj"
Fix - put #idef freebsd version < 500000 for
bmaj -1 -> amrd_cdevsw
(4) Problem: warnings in driver when compiling
with DAMR_DEBUG param enabled in Makefile
Fix - fix the warnings so driver can compile
when -Werror is present in Makefile.

9f1776230d Major update to the AMI MegaRAID driver.
- New support for 40LD firmware found in Series 475 and 471 adapters.
 - Better support for 8LD firmware adapters
 - Ioctl passthrough interface for userland utilities.
 - Improved error handling and queueing.
 - Several bugfixes (including the 'still open' shutdown bug and
   closing some small race conditions).
 - Zone-style command allocator, reducing memory wasted under heavy
   load conditions.
 - CAM interface (disabled and not fully working) for SCSI passthrough
   access to non-disk devices

Thanks to AMI for supplying a pile of new adapters and various other
help in making this happen.
