* error - error reporting function
*
* If len != 0, inbuf should contain all the necessary input data, and fill
* should be NULL
* If len = 0, inbuf can be NULL, in which case the decompressor will allocate
* the input buffer. If inbuf != NULL it must be at least XXX_IOBUF_SIZE bytes.
* fill will be called (repeatedly...) to read data, at most XXX_IOBUF_SIZE
* bytes should be read per call. Replace XXX with the appropriate decompressor
* name, i.e. LZMA_IOBUF_SIZE.
*
* If flush = NULL, outbuf must be large enough to buffer all the expected
* output. If flush != NULL, the output buffer will be allocated by the
* decompressor (outbuf = NULL), and the flush function will be called to
* flush the output buffer at the appropriate time (decompressor and stream
* dependent).
