Allow an ALPN callback to pretend to not exist

RFC 7301 mandates that the server SHALL respond with a fatal
"no_application_protocol" alert when there is no overlap between
the client's supplied list and the server's list of supported protocols.
In commit 062178678f5374b09f00d70796f6e692e8775aca we changed from
ignoring non-success returns from the supplied alpn_select_cb() to
treating such non-success returns as indicative of non-overlap and
sending the fatal alert.

In effect, this is using the presence of an alpn_select_cb() as a proxy
to attempt to determine whether the application has configured a list
of supported protocols.  However, there may be cases in which an
application's architecture leads it to supply an alpn_select_cb() but
have that callback be configured to take no action on connections that
do not have ALPN configured; returning SSL_TLSEXT_ERR_NOACK from
the callback would be the natural way to do so.  Unfortunately, the
aforementioned behavior change also treated SSL_TLSEXT_ERR_NOACK as
indicative of no overlap and terminated the connection; this change
supplies special handling for SSL_TLSEXT_ERR_NOACK returns from the
callback.  In effect, it provides a way for a callback to obtain the
behavior that would have occurred if no callback was registered at
all, which was not possible prior to this change.

e_os2.h: Refine OSSL_SSIZE definition under UEFI environment

Under UEFI build environment, we may encounter the OSSL_SSIZE macro
re-definition error in e_os2.h if any module call OpenSSL API directly
by including "openssl/xxxx.h" (caused by the predefined _WIN32/_WIN64
macro, which should have been un-defined under OPENSSL_SYS_UEFI).

Though it's not one recommended usage, this patch could still eliminate
the possible build issue by refining the OSSL_SSIZE definition under
OPENSSL_SYS_UEFI.

In rand_cleanup_int(), don't go creating a default method

If no default method was yet given, RAND_get_rand_method() will set it
up.  Doing so just to clean it away seems pretty silly, so instead,
use the default_RAND_meth variable directly.

This also clears a possible race condition where this will try to init
things, such as ERR or ENGINE when in the middle of a OPENSSL_cleanup.
