Changing the framework to call init_static_data only the first time the
codec is ever opened seems like the obvious thing to do. It requires an
atomic flag per codec, I think we can devise a way.

By the way, the sine table generator in asrc_sine is significantly
faster than the float version from the libc, and bit-exact with itself
to boot, maybe you can make use of it.
