* Add C++ ifdefs around C++ code.
The purpose of this change is to gate C++ code behind a cplusplus define so that FLEX can be made into a module for Swift code. Swift modules do not allow for C++ code. However this means if FLEX is used a Swift module, it will not have functionality of the excluded code. Ideally in the future, FLEX can be converted fully to support Swift without bridging headers.
* Revert "Add C++ ifdefs around C++ code."
This reverts commit 77c02207f9.
* Add include <Foundation/Foundation.h> to ActivityStreamSPI header
We use a different build setup internally, and we need all headers to be able to stand on their own. This file is using NS_ENUM, which is defined in Foundation, without importing it, so we're adding the import to resolve that.
