Some of the routines were using artificially limited builtin already,
drop the explicit limit.
The use of builtins allows quite often allows the compiler to elide the call
or most zeroing to begin with. For instance, if the target object is 32 bytes
in size and gets zeroed + has 16 bytes initialized, the compiler can just
add code to zero out the rest.
Note not all the primites have asm variants and some of the existing ones
are not optimized. Maintaines are strongly encourage to take a look
(regardless of this change).
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 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.

instead of including the userland string.h header.
Prompted by: breakage with old string.h from recent machine/types.h fix

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