bug:8037003 Changes the DisplayList from using stream read/write commands to use an array of objects manually allocated on a linear buffer. Depends on frameworks/native change https://googleplex-android-review.googlesource.com/#/c/257695/ which adds LinearAllocator Also changes drawRects to use float count instead of rect count, to be more like drawLines/drawPoints Change-Id: Ia2e4a11acd8f0a757042a05cbc9e7563cb73ee47
