4c72471cdb Changes to move output sample path from 16bit to 32 bit
AAC Core coder changes to take the output samples as 32 bit
and subject to peak limiter to avoid any clipping , at the
same time maintaining precision.

Array common_gain_element_present was accessed with an index of 10,
so a check has been added as fix and error return code handling has
been modified.

cd952cc64e Fix for multiply overflow in coupling channel element decoding
The numbers stored in the table
common_tables_ptr->cc_gain_scale are multiplied with itself,
((-norm_value) - 1) times and stored in ind_channel_info->cc_gain.
Since the number stored in common_tables_ptr->cc_gain_scale
has a q factor of 29, the result is right shifted by 29 to maintain
the same q factor.
