Remove copyright strings ifdef'd out

We've ifdef'd out the copyright strings for some time now. Go ahead and
remove the ifdefs. Plus whatever other detritis was left over from other
recent removals. These copyright strings are present in the comments and
are largely from CSRG's attempt at adding their copyright to every
binary file (which modern interpretations of the license doesn't
require).

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).

env(1): grow -L user/class and -U user/class options

This allows one to set the environment of the specified user either from

This is a supporting feature to allow service(8) to pull in the environment
of the "daemon" class before invoking the rc script.

This is a part of D21481.

General further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 3-Clause license.

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.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

Significantly reduce the memory leak as noted in BUGS section for
setenv(3) by tracking the size of the memory allocated instead of using
strlen() on the current value.

Convert all calls to POSIX from historic BSD API:
- unsetenv returns an int.
- putenv takes a char * instead of const char *.
- putenv no longer makes a copy of the input string.
- errno is set appropriately for POSIX. Exceptions involve bad environ
variable and internal initialization code. These both set errno to
EFAULT.

Several patches to base utilities to handle the POSIX changes from
Andrey Chernov's previous commit. A few I re-wrote to use setenv()
instead of putenv().

New regression module for tools/regression/environ to test these
functions. It also can be used to test the performance.

Bump __FreeBSD_version to 700050 due to API change.

Back out all POSIXified *env() changes.

Not because I admit they are technically wrong and not because of bug
reports (I receive nothing). But because I surprisingly meets so
strong opposition and resistance so lost any desire to continue that.

Anyone who interested in POSIX can dig out what changes and how
through cvs diffs.

Add the '-S' and '-P' options. The '-S' option can be used to split
apart a string, and supports some text substitutions. This can be
used to provide all the flexibility (and more!) that was lost by recent
changes to how the kernel parses #!-lines in shell scripts.

The '-P' option provides a way to specify an alternate set of directories
to use when searching for the 'utility' program to run. This way you can
be sure what directories are used for that search, without changing the
value of PATH that the user has set. Note that on FreeBSD 6.0, this
option is worthless unless the '-S' option is also used.
