spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD

The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch
up to that fact and revert to their recommended match of BSD-2-Clause.

sys/dev: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Various fixes to hptiop(4):
- Use callout(9) instead of timeout(9).
- Use the existing hba lock as the CAM sim lock instead of Giant.
- Mark interrupt handler MPSAFE.
- Reorder detach and destroy the hba lock in detach.

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.

- Import the HEAD csup code which is the basis for the cvsmode work.

- Spell cam correctly (scbus), this makes it possible to compile hptiop
in GENERIC and LINT. [1]
- Rename hpt_dbg_level to hpt_iop_dbg_level to avoid multiple definition
of hpt_dbg_level (hptmv also has hpt_dbg_level).
