[PATCH 02/25] efw-downloader: efw-proto: define EfwProto as derived object of HinawaFwResp

[Takashi Sakamoto]

Echo Digital Audio corporation designed specific protocol to operate
Fireworks board module. The protocol includes a pair of asynchronous
transactions on IEEE 1394 bus to transfer command frame and receive
response frame.

This commit adds EfwProto GObject object. This object inherits
HinawaFwResp to receive the response frame from Linux 1394 OHCI driver,
thus libglib-2.0, libgobject-2.0 and libhinawa 2.1 is added for
build and runtime dependency.
