RFR 8133632: javax.net.ssl.SSLEngine does not properly handle received SSL fatal alerts

[Jamil Nimeh]

Hello folks,

This fixes an issue in SSLEngine that happens when an engine unwraps a 
TLS fatal alert record.  The resulting engine state still leaves both 
input and output queues in an open state, and in NEED_UNWRAP. Unwrapping 
just causes the exception thrown as a result of processing the exception 
to be thrown again.

This fix updates the resulting state of the engine in this particular 
case to have both I/O queues closed and updates the state of the engine 
to NOT_HANDSHAKING.
