(cherry picked from commit 62ecd3635a)

This patch changes the exponent difference threshold in the exponent
strategy decision function of the AC-3 encoder.  I tested lowering in
increments of 100.  From 1000 down to 500 generally increased in quality
with each step, but 400 was generally much worse.

This will be beneficial for use with the audio conversion API without
requiring it to depend on all of dsputil.

(cherry picked from commit e0eb963aaa)

This moves the fields needed by asm near the top, before any
structs or other members which complicate the offset calculation.
Modifying other structs will no longer require updating the offsets,
and the asm code is slightly simpler due to the smaller offsets.
