This renders decoder unusable in some cases - for example,
http://samples.mplayerhq.hu/A-codecs/lossless/wavpack/crc_error-decoded_correctly_by_wvunpack.exe_4.40.wv
requires output buffer of size 44100*2*4 bytes, which is about twice as much
as current limit for output buffer; same situation with many lossy compression
samples (http://samples.mplayerhq.hu/A-codecs/lossless/wavpack/test_suite/hybrid_bitrates/).

If you convince Michael to increase AVCODEC_MAX_AUDIO_FRAME_SIZE, I'll apply
the rest of patches.
