85c8521e67 env(1): grow -L user/class and -U user/class options
This allows one to set the environment of the specified user either from
login.conf alone (-L) or both login.conf and ~/.login_conf if present (-U).

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.

8a16b7a18f 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.

fbbd9655e5 Renumber copyright clause 4
Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

a414225db1 Add the '-u name' option to the env command, which will completely unset
the given variable name (removing it from the environment, instead of
just setting it to a null value).

2966d28c32 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.

ba174a5e38 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.

ed4bcacfde env calls setenv("name=value", "value", 1); which violates POSIX:
"The setenv( ) function shall fail if:
[EINVAL] The name argument is a null pointer, points to an empty string,
or points to a string containing an '=' character."
The fix (like all others in this subject) is backward-compatible.

2f739d3c1a Undo r1.14 to env.c. While it is unusual for environment variables to
start with a '/', they are more supported (by POSIX and SUSv3) than
filenames which have an '=' in them.

8fbe7ebf7d 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.

6dcd6cac03 If the `utility' specified starts with a '/' character, then execute it
without checking it for an equals-sign.  If it starts with a slash, then
it cannot be a request to set the value of a valid environment variable.

212274c3b6 Move the code that clears the environment when `-i' is specified, so it that
it does not happen until all single-letter options are processed.  This will

executes in the usage() message and manual page. Use "utility" instead of
"command" in both places to emphasise that shell builtins etc. will not work,
and to be consistent with the terminology used by POSIX.
