This is off by default for now. And autotools-only. But after significant preparatory work, we're now able to do it cleanly. Stuff that was previously exported just for tests (like page heap stuff or flags) is now unexported. Just like on windows all symbols explicitly exported by PERFTOOLS_DLL_DECL are visible and exported and rest are hidden. Those include all the malloc/new APIs of course, and all the other symbols we advertise in our headers (e.g. MallocExtension, MallocHook). Updates issue #600
