ALPN / NPN need to handle no compatible protocols found

Motivation:
If there are no common protocols in the ALPN protocol exchange we still compete the handshake successfully.  This handshake should fail according to http://tools.ietf.org/html/rfc7301#section-3.2 with a status of no_application_protocol.

Modifications:
-Upstream project used for ALPN (alpn-boot) does not support this.  So a PR https://github.com/jetty-project/jetty-alpn/pull/3 was submitted.
-The netty code using alpn-boot should support the new interface (return null on existing method).
-Version number of alpn-boot must be updated in pom.xml files

Result:
-Netty fails the SSL handshake if ALPN is used and there are no common protocols.
Right now we do not, but this PR does not add/modify any existing OpenSSL code.  The thought is this interface structure (although not complete) will be consistent with the JDK side.  It is also not known what this interface will look like and at this point is only known to likely be needed.  The rational for not knowing what it will look like is the following:

1. Not sure what level of interface this will be (JNI, java, tcnative hooks, etc...).
2. OpenSSL itself currently is not in compliance with the specs (and does not provide the interface we require to be consistent with the JDK implementation).  I have reported an issue with a suggested approach but I'm not sure how that will actually be implemented.

My mental model is when ALPN supported is added of openssl this can be either filled out or re-visited to determine if it is necessary.
