This reverses #3095. Rationale: * We're now exposing source attributes as a public API. Making those attributes unavailable at certain times complicates that API. * We're preparing to split RenderSource out of Source. Removing this removes a point of coupling between the two.
Darwin
The code in the Darwin platform targets Apple platforms but is not specific to iOS or macOS. This code is not distributed as an SDK in itself, but is required by the Mapbox iOS SDK and Mapbox macOS SDK.
These files depend on the Foundation and Core Foundation frameworks but do not depend on iOS- or macOS–specific frameworks, such as UIKit or AppKit. Any non-cross-platform code is guarded by TargetConditionals.h macros.
