2b83592fdc Remove Giant from CAM. Drivers (SIMs) now register a mutex that CAM will 
use to synchornize and protect all data objects that are used for that
SIM.  Drivers that are not yet MPSAFE register Giant and operate as
usual.  RIght now, no drivers are MPSAFE, though a few will be changed
in the coming week as this work settles down.

The driver API has changed, so all CAM drivers will need to be recompiled.
The userland API has not changed, so tools like camcontrol do not need to
be recompiled.

4ed23cf283 - Use a regular mutex rather than a spin mutex. This driver doesn't need 
a spin mutex since it doesn't have an INTR_FAST interrupt handler.
  Beyond that the driver is still under Giant anyway.
- Remove unneeded locking during attach across operations that can't be
  called with locks held (such as bus_dma_tag_create()).

b49a9e5bab Don't augment the DRIVER_VERSION "v1.12" with __DATE__ and __TIME__. 
This is the only file of > 1700 files in a buildkernel here doing that.
It makes reproducible builds (same source => same binary) impossible.

d2bd3ab995 Import new version of the HPTMV driver from Highpoint. The major change 
here is the support for amd64, as well as possible support for PAE.  Many
thanks to Highpoint for continuing to support FreeBSD.

d4fcf3cba5 Remove bus_{mem,p}io.h and related code for a micro-optimization on i386 
and amd64.  The optimization is a trivial on recent machines.

d38d9c9e5e Move all of the hptmv files to /sys/dev/hptmv so that they won't be mistaken 
for being on a CVS vendor branch.  The files were moved via a repo-copy.
