This speeds up dumping make variables from ~380ms using make to ~220ms using ckati. It also means that we're consistently using the same parser for builds (with the same .KATI_READONLY/etc extensions). envsetup.sh (lunch) / other scripts still use make, changing those to go through soong_ui will be a future change. Test: m clean; m nothing Test: USE_GOMA=true m nothing Test: m PRODUCT-aosp_x86-sdk Test: m APP-Calculator Test: build/soong/build_test.bash -only-config (on AOSP and internal master) Change-Id: I6ca554de8de4955fb869001d06d29969b75751cc
