Adding WebSocket per-frame DEFLATE extension
https://bugs.webkit.org/show_bug.cgi?id=77522
Source/JavaScriptCore:
Added USE(ZLIB) flag.
Reviewed by Kent Tamura.
Source/WebCore:
Add WebSocketDeflateFramer class which handles deflate-frame extension.
This class encapsulates WebSocketDeflater and WebSocketInflater classes,
which depend on zlib, so that WebSocketChannel is not necessary to aware
zlib dependency.
