Original commit message:
Very evil missuse of svn to test if AVOption and AVOption2 are compatible.
If this test triggers anywhere for anyone, revert this commit immedeatly.
Ill revert this in a day or 2, its just so we know beforehand if the idea
with the union is doable or not without breaking ABI/API.

work_chunks_* and dv_idct_factor_* variables appear only once in the binary
instead of 3 times.

initialized by ff_fft_init and using different code can result in slightly
different values, in addition it crashes when the tables are hardcoded.
On amd64 this slightly changes qdm2 output.

This hopefully is fast enough so that it is reasonable to use the same formula
directly instead of the table for CONFIG_SMALL.

--enable-hardcoded-tables was used.
Due to the size, the code for the tables is generated at compile time.

buffers e.g. in the decode_end function.

- clarify when 0 is returned
- explain that decode_audio3 has to be called multiple times when there
are multiple frames in a single packet

This allows for some simplifications like removing some outer loops
and gives much better performance for thread_count > number of idle CPUs.

processing with jobs > threads without wasting too much memory.
It also avoids needing a separate int array when the only additional data
the jobs needs is a single int running from 0 to count-1.

A certain rotten fruit operating system doesn't provide the 8-byte stack
alignment required by the standard ARM ABI, so align it manually.
