bta_av_sbc_up_sample() function

* Function bta_av_sbc_up_sample * Description Given the source (p_src) audio data and * source speed (src_sps, samples per second), * This function converts it to audio data in the desired format * p_src: the data buffer that holds the source audio data * p_dst: the data buffer to hold the converted audio data * src_samples: The number of source samples (number of bytes) * dst_samples: The size of p_dst (number of bytes) * Note: An AE reported an issue with this function. * When called with bta_av_sbc_up_sample(src, uint8_array_dst..) * the byte before uint8_array_dst may get overwritten. * Using uint16_array_dst avoids the problem. * This issue is related to endian-ness and is hard to resolve * in a generic manner. * **************** Please use uint16 array as dst. * Returns The number of bytes used in p_dst * The number of bytes used in p_src (in *p_ret)
