Outer loop: controls masking conditions and computes best scalefac and global gain Corresponds to shine_outer_loop() in l3loop.c

The outer iteration loop controls the masking conditions of all scalefactorbands. It computes the best scalefac and global gain. This module calls the inner iteration loop.
