-Subject: Clear context from orphan handlers when BaseAudioContext is going
- away
-
-When preparing to collect a BaseAudioContext, go through all the
-rendering_orphan_handlers_ and deletable_orphan_handlers_ and remove
-the context from the handler.  This ensures that these handlers no
-longer have references to the context when the BaseAudioContext is
-destroyed because in some cases, these orphan handlers will get pulled
-and access the context, which is already gone.
-
-Clearing these in a prefinalizer ensures these orphan handlers don't
-try to touch the context.
-
-Manually verified that the repro case no longer reproduces.
-
-Bug: 1062247

 Explicitly #include <ostream> in quic/platform/api/quic_ip_address.h, since std::ostream is referenced in it. In the C++ STL shipped with Visual Studio 2019, none of the headers included in quic_ip_address.h ends up including the required templates, which caused a compile error.
