Make the hpt27xx(4) driver MPSAFE.
- Use the existing vbus locks instead of Giant for the CAM sim lock.
- Use callout(9) instead of timeout(9).
- Mark the interrupt handler as MPSAFE.
- Don't attempt to pass data in the softc from probe() to attach().

Re-do r255853. Along with adding back the API/ABI changes from the
original, this hides the contents of cam_compat.h from ktrace/kdump/truss,
avoiding problems there. There are no user-servicable parts in there, so
no need for those tools to be groping around in there.

Update the CAM API for FreeBSD 10:

- Remove the timeout_ch field. It's been deprecated since FreeBSD 7.0;
MPSAFE drivers should be managing their own timeout storage. The
remaining non-MPSAFE drivers have been modified to also manage their own
storage, and should be considered for updating to MPSAFE (or removal)
during the FreeBSD 10.x lifecycle.

- Add fields related to soft timeouts and quality of service, to be used
in upcoming work.

- Add room for more flags in the CCB header and path_inq structures.

- Begin support for extended 64-bit LUNs.

- Bump the CAM version number to 0x18, but add compat shims. Tested with
camcontrol and smartctl.

- Don't include date and time the driver is built, this is useful for
generating binary diffs.
- Constify a few strings used in the driver.
- Style changes to make the driver compile with default clang settings.
