added decoder_read()
On our way to stabilize the decoder API, we will one day remove the input stream functions. The most basic function, read() will be provided by decoder_api.h with this patch. It already contains a loop (still with manual polling), error/eof handling and decoder command checks. This kind of code used to be duplicated in all decoder plugins.
