RFR: 8087124 HTTP/2 implementation

[Michael McMahon]

Hi,

An updated webrev is available at:

http://cr.openjdk.java.net/~michaelm/8087124/webrev.2/

The main change is the removal of the permanently allocated
two threads per TCP connection (for HTTP/2)

Now, all socket reads and writes are done by the selector thread
(writes also happen on other threads). Asynchronous writes use the
same write() calls as the blocking interface. A new type AsyncConnection
defines a callback interface for asynchronous reads (and error reporting).
This interface is implemented by PlainHttpConnection and a new 
AsyncSSLConnection
(and AsyncSSLDelegate which is a non-blocking version of SSLDelegate).

Thanks
Michael
