spdx: initial adoption of licensing ID tags.

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.

Initially, only tag files that use BSD 4-Clause "Original" license.

Various changes to make locate compilable with WARNS=6. Note that there
is still one issue on FreeBSD/arm (signed vs unsigned char) which prevents
actually bumping this to WARNS=6 - I'm still considering the correct
solution to this issue.

remove __P

getopt and friends are declared in <unistd.h>
getopt returns -1 not EOF.

$Id$ -> $FreeBSD$

Finish importing Lite2's src/usr.bin, except for ex, diff, grep, mail,
pascal and vmstat.sparc. All changed files on the vendor branch should
already have been imported.

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

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Do not store character 30. I made a test at my CS department
and at least one user use this char in a file name. Older
locate implementions core'd.

8-Bit character support.

Old locate(1) programs still works with the new database format, print
some garbage for 8 bit characters, but don't core (maybe except char 30).

7-Bit Puritan should not notice any difference. Same speed,
Same database size if the database contain only ASCII characters.

Bigram does not check for characters outside 32-127.

The bigram output is silly and need ~1/2 CPU time of
database rebuilding.

old:
locate.bigram < $filelist | sort | uniq -c | sort -nr
^^^^^^^^^^^^^^
this can easy made bigram

new:
bigram < $filelist | sort -nr

code
Code does not check for char 31.
Use a lookup array instead a function. 3 x faster.
