If everything works fine for 16-bit streams,
the current code could be extended to do 24-bit.

Not sure if this is correct. But looks like
it was giving us off-by-one's when used to index
buffers.

(Resolves some conflicts)

Size should be determined from bits per sample.
The current code only accepts 16-bit streams.

Fix building with --disable-network.

Although gcc guarantees 16 byte stack alignment, threads under WinXP
don't appear to be guaranteed to start stack aligned.  So fix the
alignment.

A new field, AVCodecContext.internal is used to hold a new struct
AVCodecInternal, which has private fields that are not codec-specific and are
used by general libavcodec functions.

Moved internal_buffer, internal_buffer_count, and is_copy.
