AC3 sample to reproduce the problem

Thanks for porting a52dec to audioencoder. But it seems that the behavior
changed about "discont" buffers.

 * Steps to reproduce:

gst-launch-0.10 filesrc location=sample.ac3 ! ac3parse ! a52dec ! fakesink

 * Actual result:

GstPipeline:pipeline0/GstA52Dec:a52dec0: Could not decode stream

 * Previsous result:

No error

 * Other informations:

The check around "if (a52_block (a52dec->state))" and "if (a52_frame)" is now a
GST_AUDIO_DECODER_ERROR. Previously it was a GST_WARNING with a discont=TRUE.
Also the line "GST_BUFFER_FLAG_SET (buf, GST_BUFFER_FLAG_DISCONT);"
disappeared.
