service: Add -E option to set environment variables before starting a service.

This allows for quicker testing/debugging of rc scripts and is a pre-req

spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD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

service(8): use an environment more consistent with init(8)

init(8) sets the "daemon" login class without specifying a pw
entry (so no substitutions are done on the variables). service(8)'s
use of env -L had the effect of specifying root's pw entry, with two
effects: getpwnam and getpwuid are being called, which may not be
entirely safe depending on what nsswitch is up to and what stage of
boot we are at, and substitutions would have been done.

Fix by teaching env(8) to allow -L -/classname to set the class
environment with no pw entry at all specified, and use it in
service(8).

service: respect nojailvnet keyword

In the 761d2bb5b9e70cf30f9c2dac62a47a2d2593e83f we added nojailvnet
keyword. The nojailvnet keyword is used to skip startup scripts in
jails that are run without VNET.

The service.sh was omitted in this commit. The service.sh
even documents that this is the same code as in rc - so lets reflect
that.

service(8): set the environment of the "daemon" class before invoking

As mentioned in r357562, this gives the user a single place to configure
environment variables that need to be used for various services -- the
"daemon" class -- for, e.g., configuring a system-wide HTTP proxy.

This is a part of D21481.

Use "$@" instead of $* to cope with parameters that have spaces in
them. "$@" preserves the args with spaces properly.

usr.sbin/service: Fix -j to not be order dependant

The introduced -j option is highly dependant on the ordering of arguments,
and it exhibited broken behavior in some other circumstances. Fix these
issues, and simplify the feature by removing the unneessary double parsing
of options.

service(8): Reset OPTIND properly now that we're parsing args twice

r328032 introduced a second round of argument parsing to proxy the request
through to a jail as needed, but failed to reset OPTIND before getting to
the second round of parsing to allow other flags to be set.

service(8): Add support for interfacing with services in jails

Provide a -j option that can take a jail name or id. If -j is specified,
check that the jail exists and proxy the service request through to
service(8) in the jail.

This allows for cleaner workflows when updating services in a jail, turning
the following:

pkg -j dns upgrade
jexec dns service named restart

into:

pkg -j dns upgrade
service -j dns named restart

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.

Fix an issue with service(8) where utilities such as screen(1) and tmux(1)
would behave differently when utilizing rc-script was invoked manually vs.
service(8). The issue being that these utilities require the TERM environ
variable to be set and service(8) was not passing it down.

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.
