Some of the TLS library wrappers defined only an empty function for
tls_connection_set_success_data(). That could result in memory leaks in
TLS server cases, so update these to do the minimal thing and free the
provided buffer as unused.

TLS 1.3 sends the OCSP response with the server Certificate message.
Since that Certificate message is not sent when resuming a session,
there can be no new OCSP response. Allow this since the OCSP response
was validated when checking the initial certificate exchange.

It looks like the OpenSSL callbacks for SSL_SESSION can end up calling
the remove callback for multiple SSL_SESSION entries that share the same
ex data. This could result in double freeing the session data on the
server side.
Track the SSL_SESSION ex data in a separate list and free the
allocations only if they are pointing to a valid allocated wpabuf
pointer.

The result (y2) was cleared and freed in error cases, but the pointer
itself was not cleared to NULL, so the error path would have returned a
pointer to freed memory. Fix this by properly clearing the return value
in error cases. In addition, simplify the function to avoid tracking
success case separately.

wc_HmacSetKey() seems to initialize everything that is needed for the
actual operation, but at least valgrind is reporting use of
uninitialized values when this was done on a data structure that was not
explicitly cleared.
Call wc_HmacInit() before wc_HmacSetKey() to avoid any unexpected
behavior from potentially uninitialized values.

The previous mechanism of unloaded the providers from tls_deinit() did
not work correctly for some cases. In particular, it was possible for
hostapd to end up unloading both providers and not being able to recover
from this if TLS server was not enabled.
Address this more cleanly by introducing a new crypto_unload() function
that will be called when the process is exiting.
