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.

- 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.

Implement compile time debug support for spinlocks.
...
Simplify the atomic lock prototype, removing the lock value.
Delete the unlock prototypes that are not required.

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.

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.
