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.

07f29d9f76 Remove old spinlock_debug code from libc
This no longer seems useful.  Remove it.

This was prompted by a "cast discards volatile qualifier" warning
in libthr when WARNS=6.

82358b1b5a Remove #include of spinlock.h from libc_private.h. Declare spinlocks as
struct _spinlock.  Keep the typedef in for now; another set of changes
may come around to clean up consumers of spinlocks.

cc3521d660 - Define a _spinunlock() function so that threading implementations may do
more complicated things than just setting the lock to 0.
 - Implement stubs for this function in libc and the two threading libraries
   that are currently in the tree.

f374bfcd3c Implement compile time debug support for spinlocks.
Simplify the atomic lock prototype, removing the lock value.

Delete the unlock prototypes that are not required.

f1daac6f22 In a threaded library, expect the lock field to be declared volatile,
so provide function prototypes that respect that, avoiding a gcc
warning that `volatile' is being thrown away.

0a31d34120 Add a private (to libc, libc_r and libpthread) header file containing
prototypes for the spinlock functions that will be used for thread locks.
libc will have stubs declared with weak symbols. libpthread and libc_r
will have functions that really do something.
