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.

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.

db(3): Fix aliasing warnings from modern GCC.

Obtained from: NetBSD (CVS Rev. 1.20)

Fix clang warnings.

Update SCCS IDs for Berkeley DB 1.86 merge.

style: operators should appear at the line end if we have to wrap.

Several signed/unsigned warning fixes.

When allocating memory, zero out them if we don't intend to overwrite them
all; before freeing memory, zero out them before we release it as free
heap. This will eliminate some potential information

When allocating memory, zero out them if we don't intend to overwrite them
all; before freeing memory, zero out them before we release it as free
heap. This will eliminate some potential information leak issue.

While there, remove the PURIFY option. There is a slight difference between
the new behavior and the old -DPURIFY behavior, with the latter initializes
memory with 0xff's. The difference between old and new approach does not
generate observable difference.

I found "portsdb -u" dumps core with recent INDEX file, and this is
caused by refering broken (uninitialized?) pointer which is retrieved
from __bt_new() (and from mpool_new()).

I don't know why this linp[0] is read before stored because this
should be controlled by .lower and .upper member of PAGE structure
which are correctly initialized.

But this workaround fixes the problem on my environment and this
module has #ifdef PURIFY option which initializes new and reused
memory from mpool by memset(p, 0xff, size) like as I did.

Please feel free to fix the real bug instead of my workaround.

Eliminate 61 warnings emitted at WARNS=2 (leaving 53 to go).
Only warnings that could be fixed without changing the generated object
code and without restructuring the source code have been handled.
