spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD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

various: general 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.

No functional change intended.

Stop suggesting -grope argument when -grope argument was actually given

Pass the size of the top-level table to map when mapping the table instead
of the size of the pointer.

- Use <x86/mptable.h> instead of duplicating its definitions.
- Switch to mmaping the table from RAM instead of reading it out of
/dev/mem via read(2).

Divine the array size by using 'nitems(array)' instead of using magic numbers.

Suggested by: Garrett Cooper

The MPtable specification allows for an 8-bit "BUS ID" and "I/O APIC ID".

Since the 'busses[]' and 'apics[]' arrays are indexed by these 8-bit IDs
make sure that they have enough space to accomodate up to 256 entries.

Add an missing argument to open(2). If O_CREAT flag is specified,
file permission has to be specified as well.

Mark all global variables static for mptable(1).

While there, remove basetableEntryTypes, which became unused in r71209.

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

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

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

Remove the useless "version" number output.
We don't give a version number each userland binary.

Make this build and work on amd64 (sledge at least).

Don't need to redundantly redeclare optreset.

Deal with table parsing bugs caused by out-of-order record entries.
Complain about out-of-order entries. This fixes the 'mp extended
table HOSED!" report on the DL360 we have here with the "fixed" compaq
bios rom to fix the table length off-by-one error.

Add `_PATH_DEVZERO'.
Use _PATH_* where where possible.

Stop printing out the Nfoo options help, since these tunables are about to
go away.

Remove 3 off by 128 errors.

getopt(3) returns -1 not EOF.

Don't #include implementation header <machine/types.h> directly.
#include <sys/types.h> before the headers that depend on it.

Use err(3). Add missing parameter for printf() (reviewed by steve).

Changed the Ints labels for the IO APIC from "INT#" to "PIN#" to better
reflect its logical usage. Ie., there is NOT a 1-to-1 correspondence
between IRQ numbers and APIC pin numbers as there is with the 8259 ICU.

Removed suggested "options AUTO_START", no longer used.

Removed the SMP_TIMER_NC suggestion.
This is (almost) defunct, start to phase it out...

Removed SMP_PRIVPAGES from options list.
This functionality is now automatic.

Made 'options NINTR' greater of 24 and calculated value.
This coincides with changing kernel default to 64.

Document APIC_IO as mandatory.
Document SMP_AUTOSTART as working.

fixed minor typo, bumped to version 2.0.9
