makefs: call brelse from bread

This matches NetBSD and rationalizes makefs with the kernel API.

This reverts commit 370e009188ba90c3290b1479aa06ec98b66e140a.

makefs: Cast daddr_t to off_t before multiplication

Apparently some large-file systems out there, such as my powerpc64le
Linux box, define daddr_t as a 32-bit type, which is sad and stymies
cross-building disk images. Cast daddr_t to off_t before doing
arithmetic that overflows.

Remove #define _KERNEL hacks from libprocstat

Make sys/buf.h, sys/pipe.h, sys/fs/devfs/devfs*.h headers usable in
userspace, assuming that the consumer has an idea what it is for.
Unhide more material from sys/mount.h and sys/ufs/ufs/inode.h,
sys/ufs/ufs/ufsmount.h for consumption of userspace tools, with the
same caveat.

Remove unacceptable hack from usr.sbin/makefs which relied on sys/buf.h
being unusable in userspace, where it override struct buf with its own
definition. Instead, provide struct m_buf and struct m_vnode and adapt
code to use local variants.

makefs: use FreeBSD brelse function signature

Although the ffs (and later msdosfs) implementation in makefs is
independent of the one in kernel, it makes sense to keep differences to
a minimum in order to ease comparison and porting changes across.

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.

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.
