Features added
The protocols CONNECT destination option has been added as a replacement for the now deprecated protocol option.

Add the h2specd HTTP/2 test suite from the h2spec project.

Do not crash on HTTP/2 HEADERS frames with the PRIORITY flag set.
Do not crash on HTTP/2 HEADERS frames when the END_HEADERS flag is not set.
Do not crash on unknown HTTP/2 frame types.
Reject HTTP/2 WINDOW_UPDATE frames when they would cause the window to overflow.
Send a GOAWAY frame on closing the HTTP/2 connection.
