PLATFORM_VERSION_ALL_CODENAMES isn't actually all the code names, just the ones active in our current target. We need the list of all targets so we can validate code names in NDK stub templates even if they're in the future. Unfortunately, all_codenames has been baked into build.prop for ages, so we're stuck with this name. Improve the comments and add PLATFORM_VERSION_FUTURE_CODENAMES to cover to cover the future targets. Test: make checkbuild Test: check $ANDROID_PRODUCT_OUT/system/build.prop Bug: None Change-Id: I81fed6f761e5362ef3050be9d1e3fb17739feadd
