Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.

Revert with prejudice.

This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.

Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

Partial merge of the SPDX changes

These changes are incomplete but are making it difficult
to determine what other changes can/should be merged.

No objections from: pfg

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

ANSIfy some more tools in usr.sbin/.

Most of these tools build with WARNS=6, except for their use of K&R
function declarations.

Per letter dated July 22, 1999, delete clause 3 from code directly

Use __FBSDID over rcsid[]. Protect copyright[] where needed.

WARNS=4, de-__P()

$Id$ -> $FreeBSD$

Use err(3).

compare return value from getopt against -1 rather than EOF, per the final
posix standard on the topic.

Remove trailing whitespace.
