v0.3.6

What's Changed

=> Speedup dynarec, and allow the use of BIGBLOCK 2 or 3 combined with CALLRET on more software

• Wrapping: More libs and function wrapping (gtk3, vulkan...)
• Reworked X11 Callback handling, for better stability
• Reworked exit and the load/unload of libs
• Some more profiles in box86rc
• More SSE3+ opcodes in dynarec
