usleep() is obsolete since POSIX.1-2001 and removed in POSIX.1-2008,
in favor of nanosleep(), which has been present since POSIX.1-2001.
The exceptions for DJGPP and TANDEM are preserved. Also, just in case
nanosleep() turns out to be unavailable on any Unix machinery that we
are unaware of, we allow a revert to using usleep() by defining
OPENSSL_USE_USLEEP.

This change ensures that sleep(0) is not invoked to cause unexpected
duplicate thread context switches when _REENTRANT is specified.

This fix also removes SPT model support as it was previously deprecated.
Upcoming threading models on the platform should be supportable without change
to this method.

As the sleep() call is interruptible, it is not even a good idea to call
it in a loop if the caller uses some ridiculously large value as an
infinity just waiting for an interrupt.

ossl_sleep() was implemented as a static inline function in internal/e_os.h,
using usleep() on Unix and Sleep() on Windows. So far well and good.
However, it also has a fallback implementation for systems that do not have
usleep() or Sleep(), and that implementation happens to use ossl_time_now(),
which is a normal function, private to libcrypto, and is judged to be too
complex to sanely make into a static inline function.
This fallback creates a problem, because we do use ossl_sleep() in apps/ and
a few test programs in test/, and when they are linked with libcrypto in
shared library form, ossl_time_now() can't be found, since it's not publicly
exposed.
Something needs to give, and the easiest, and hopefully sanest answer is to
make ossl_sleep() a publicly exposed function, which requires a slight name
change.
Documentation and 'make update' result included.
