spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD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

kerneldump: remove physical argument from d_dumper

The physical address argument is essentially ignored by every dumper
method. In addition, the dump routines don't actually pass a real
address; every call to dump_append() passes a value of zero for
physical.

ips: Remove unused devclass arguments to DRIVER_MODULE.

Ever since the block layer expanded its command syntax beyond just
BIO_READ and BIO_WRITE, we've handled this expanded syntax poorly in
drivers when the driver doesn't support a particular command. Do a
sweep and fix that.

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.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

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

Separate the hardware definitions into ipsreg.h so they can be used by
future userland tools.

Overhaul error handling in the IPS driver. Don't use a magic value for
driver-induced errors, instead be better about propagating error status
upwards. Add more error definitions, courtesy of the linux driver. Fix
a command leak in the ioctl handler. Re-arrange some of the command handlers
to localize error handling.

Add crashdump support to the ips driver. It only works for the more modern
ServeRAID 4 - 7 models right now. Support for older cards is possible, but
I don't have any hardware to experiment with.

Thanks to Jack Hammer at Adaptec for providing debugging hints.

Lock the IPS driver and bring it out from under Giant. Also do some
significant clean up and optimizations:
- don't call bioq_disksort() on every command, the hardware will do that for
us.
- remove all of the complicated bio deferral code. bio's that can't be
serviced immediately can just wait on the bioq.
- Only reserve one command object for doing control commands to the card.
This simplifies a lot of code and significantly reduces the size of the
command struct.
- Allocate commands out of a slab instead of embedding them into the softc.
- Call the command action method directly instead of having ips_get_free_cmd()
call it indirectly.

Switch from using mutexes to using semaphores to protect against early
completion of synchronous commands. Also switch to a per-array bioq as it
appears to improve performance.

Change the disk(9) API in order to make device removal more robust.

Previously the "struct disk" were owned by the device driver and this
gave us problems when the device disappared and the users of that device
were not immediately disappearing.

Now the struct disk is allocate with a new call, disk_alloc() and owned
by geom_disk and just abandonned by the device driver when disk_create()
is called.

Unfortunately, this results in a ton of "s/\./->/" changes to device
drivers.

Since I'm doing the sweep anyway, a couple of other API improvements
have been carried out at the same time:

The Giant awareness flag has been flipped from DISKFLAG_NOGIANT to
DISKFLAG_NEEDSGIANT

A version number have been added to disk_create() so that we can detect,
report and ignore binary drivers with old ABI in the future.

Manual page update to follow shortly.

Add an off_t cast to prevent overflow on media size. This should
fix issues with geometry not matching drive size.

Use __FBSDID().
Also some minor style cleanups.

Fix pointer/int warnings so this compiles on amd64. The driver wants
to store an int in the bio->bio_driver1 (a void *). It is big enough,
but you have to match the int sizes first before doing the cast.

Add the 'ips' driver for the IBM (now Adaptec) ServeRAID controller
series. This driver was generously developed and released by David
Jeffreys and Adaptec. I've updated it to work with 5.x and fixed a
few bugs.
