This splits headers into three locations: include - for backwards compatibility, the global include include_all - for things system/vendor both use include_vendor - for things that only vendors use The goal is to gradually have system things stop referencing (at least most) of these headers. Bug: 37280010 Test: build (CL on top adds back in symlinks) Change-Id: Ibf194276b7faa857e1e7605d7719f4e7d873ecba
