Hello Tanibata-San,

I am currently testing your patches against the latest Weston 1.5 release.

For this particular patch, I had to modify this section in order to compile
:

nodist_weston_ivi_shell_user_interface_SOURCES =                \
        protocol/ivi-hmi-controller-client-protocol.h           \
        protocol/ivi-hmi-controller-protocol.c                  \
        protocol/ivi-application-protocol.c

Notice the "protocol/ivi-application-protocol.c" line at the end. WIthout
it, the build process failed when linking the binary.
