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
• Better way to rename executable (including wine ones) so driver like mesa can apply the correct profile
• Reworked memory managment in the Dynarec, limiting amount of dynamic allocation
• PageSize detection and handling dynamic. Larger than 4K pagesize will be handled automaticaly.
• Lots of improvments in x87 handling (virtual stack, rounding, ffree, etc.)
