+Subject: [PATCH] sql: make VirtualCursor standard layout type
+
+sql::recover::VirtualCursor needs to be a standard layout type, but
+has members of type std::unique_ptr. However, std::unique_ptr is not
+guaranteed to be standard layout. Compiling with clang combined with
+gcc-11 libstdc++ fails because of this.

+ audio encoder
+
+AudioOpusEncoder was only used here for testing. Let's not let it get
+comfortable. We'll use MF AAC encoder here when we have it. (Soon...)
