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.

Remind people to have 'Fixes #XXXX' in the commit message

It's of course also possible to just add them to the PR description,
but having these lines in the commit messages provide better
automation.

Fixup the github pull request template

When creating a single commit PR, github will now automatically
include the commit comment first in the pull request description, and
add the template content last.  That makes the description section at
the end useless.

crypto/ppccap.c: SIGILL-free processor capabilities detection on MacOS X.

It seems to be problematic to probe processor capabilities with SIGILL

Configure: use 5.10.0, don't require...

Configure started with 'require 5.10.0', but if executed by older perl
it failed with "might be runaway multi-line // string" instead of

bio/b_print.c: switch to int64_t as "greatest-width integer type".

Originally there was dependency on BN configuration parameters, but
it stemmed from times when "long long" support was optional. Today
we require 64-bit support from compiler, and there is no reason to
have "greatest-width integer" depend on BN configuration.

bio/b_print.c: recognize even 'j' format modifier.

'j' is specified as modifier for "greatest-width integer type", which in
practice means 64 bits on both 32- and 64-bit platforms. Since we rely
on __attribute__((__format__(__printf__,...))) to sanitize BIO_print
format, we can use it to denote [u]int64_t-s in platform-neutral manner.

Fix s_client early data indicator

s_client was always saying that early_data was rejected even when it was
accepted. This was because it was using the wrong test to detect the end
of the handshake. It was using SSL_in_init() which only tells you whether
it is currently processing/sending/expecting handshake messages. It should
use SSL_is_init_finished() which tells you that no handshake messages are
being processed/sent/expected AND we have completed the handshake. In the
early data case we are not processing/sending handshake messages and we
are expecting early data (not a handshake message) - but the handshake has
not yet completed.

Fix early data bug with pause between EoED and CF

If the server received EoED then SSL_read_early_data() will return
SSL_READ_EARLY_DATA_FINISH. However if the CF has not yet been processed
then SSL_is_init_finished() will still return 0. Therefore we should still
be able to write early data.
