Subject: tinyds: Use WAYLAND_DISPLAY and WAYLAND_SOCKET for wl backend
X-Git-Tag: accepted/tizen/unified/20220720.034120~67
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=refs%2Fchanges%2F80%2F278180%2F1;p=platform%2Fcore%2Fuifw%2Flibds-tizen.git

tinyds: Use WAYLAND_DISPLAY and WAYLAND_SOCKET for wl backend

Instead of assuming the name of wayland display server by iterating
arbitrary number of names, it uses values of WAYLAND_DISPLAY and
WAYLAND_SOCKET environments.

The library of wayland-client uses these values when trying to connect
to wayland server.
