a52dec: Add patches from Handbrake project
this project hasn't been updated in 10 years, so adding patches that don't break the API should be ok. Patches: - A00: Make a52-state-t public - A01: Make it thread-safe (changing internal API by adding state objects) - A02: Quell common error - A03: Fix for automake vs autoconf
