spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD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

In sys/dev/cxgb/common/cxgb_mc5.c, remove static function
dbgi_wr_addr3(), which is unused since r167514.

- update firmware to 5.0
- add support for T3C
- add DDP support (zero-copy receive)
- fix TOE transmit of large requests
- fix shutdown so that sockets don't remain in CLOSING state indefinitely
- register listeners when an interface is brought up after tom is loaded
- fix setting of multicast filter
- enable link at device attach
- exit tick handler if shutdown is in progress
- add helper for logging TCB
- add sysctls for dumping transmit queues

When building cxgb as a module make include paths relative to the driver's root.
This will make it possible to build the module out of tree against an older src tree.

(MFp4)
- upgrade to reflect state of 1.0.0.86
- move from firmware rev 3.2 to 4.0.0
- import driver bits for offload functionality
- remove binary distribution clause from top level files as it
runs counter to the intent of purely supporting the hardware
