There are implmentations that can dead lock when calling certain functions in certain states. It works fine before HIDL because SurfaceFlinger calls those functions in another thread. We allow for 4 hwbinder threads in this commit to simulate how SurfaceFlinger calls hwcomposer. Bug: 38183197 Test: camera, videos, multi windows, screencap, screenrecord Change-Id: Ie05b2ca349b8c1ed9a3ac962981434f2efee92d9
