If "-a" option is set this make modetest use atomic API instead
of legacy API.
Test the frame rate ("-v") it does a loop and swap between two
framebuffer for each active planes.
Signed-off-by: Benjamin Gaignard <benjamin.gaignard(a)linaro.org>
---
version 3:
- merge atomic code into modetest itself
- do not change build systems
version 2 :
- make modetest_atomic compile with meson and Android
version 1:
- add dedicated modetest_atomic tool to test atomic API
