Decoder bug fixes (#60)
* Fix for divide-by-zero in ixheaacd_sbr_env_calc

These changes handle the divide-by-zero runtime error reported
while calculating the energy because the consecutive frequency bands
were coming same.

* Fix for divide-by-zero in ixheaacd_calc_stop_band

These changes handle the divide-by-zero runtime error reported
because sampling frequency comes out to be zero.

9c27c43dd7 Fix for Segmentation fault in ixheaacd_reset_acelp_data_fix func.
In ixheaacd_dec_main(),ixheaacd_config() returned from ixheaacd_read_bit_buf()
due to setjmp/longjmp changes which resulted in ixheeacd_decode_create() not
being called which is needed to initialize many pointers which in turn resulted in
Segementation fault.

As a fix, added a flag decode_create_done which will tell the status of
ixheeacd_decode_create() func and ixheaacd_usac_process will be called
based on this flag.

97fb283165 Fix for oobw in ixheaacd_decode_init()
seed_value[] is an array of size MAX_NUM_CHANNELS which is 6.
seed_value is accessed using number of channels in the stream.
For the given input number of channels are more than six,which
is causing OOB write.

As fix, check has been added based on number of channels.As
we support only stereo in USAC, we are returning error if
stream contains more than 2 channels.
