Scott Mitchell f7b3caeddc OpenSslEngine option to wrap/unwrap multiple packets per call
Motivation:
The JDK SSLEngine documentation says that a call to wrap/unwrap "will attempt to consume one complete SSL/TLS network packet" [1]. This limitation can result in thrashing in the pipeline to decode and encode data that may be spread amongst multiple SSL/TLS network packets.
ReferenceCountedOpenSslEngine also does not correct account for the overhead introduced by each individual SSL_write call if there are multiple ByteBuffers passed to the wrap() method.

Modifications:
- OpenSslEngine and SslHandler supports a mode to not comply with the limitation to only deal with a single SSL/TLS network packet per call
- ReferenceCountedOpenSslEngine correctly accounts for the overhead of each call to SSL_write
- SslHandler shouldn't cache maxPacketBufferSize as aggressively because this value may change before/after the handshake.

Result:
OpenSslEngine and SslHanadler can handle multiple SSL/TLS network packet per call.
