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
