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.

Fix decoding of ASN.1 LONG and ZLONG items

LONG and ZLONG items (which are OpenSSL private special cases of
ASN1_INTEGER) are encoded into DER with padding if the leading octet
has the high bit set, where the padding can be 0x00 (for positive
numbers) or 0xff (for negative ones).

When decoding DER to LONG or ZLONG, the padding wasn't taken in
account at all, which means that if the encoded size with padding
is one byte more than the size of long, decoding fails.  This change
fixes that issue.

Fixed PKCS5_PBKDF2_HMAC() to adhere to the documentation.

The documentation of this function states that the password parameter
can be NULL. However, the implementation returns an error in this case
due to the inner workings of the HMAC_Init_ex() function.
With this change, NULL password will be treated as an empty string and
PKCS5_PBKDF2_HMAC() no longer fails on this input.

I have also added two new test cases that tests the handling of the
special values NULL and -1 of the password and passlen parameters,
respectively.
