Initial change for DumpRrenderTree support library

This library provides:
 - An implementation of WebKitClient,
 - An implementation of WebPlugin,
 - An implementation of WebMediaPalyer,
 - Initialization and termination functions,
 - Two function for database, and
 - Some functions required by webkit_glue.

webkit_support.gyp is not referred by build/all.gyp. A gyp for DRT/chromium in
WebKit tree will refer to it.

BUG=none
TEST=none. This is a part of test code.
