udp: add a thread into udp.c for receiving data into a circular buffer, this stops the problem of live decoding/encoding giving errors.

Also added a buf_size which is the number of TS packets that to be allocated for the circular buffer.

Also makes the bpp_tab non static const, as it needs to be changed in
this case.

Fix encoding of monow/monob images, fix trac issue #193.

Reduce code duplication, increase robustness.

Fix decoding of file Test_1bpp.tif, fix trac issue #171.

Helps debugging.

This allows more 3rd party applications to correctly read
the resulting wav files.

The later parsing of payload data depends on the configuration
being present. If it hasn't been configured properly yet,
parsing a data packet may lead to a crash.

This allows the values to be used without changing C code and is closer to how
the other DEBUG flags work.

In the main loop, stream_number is incremented after checking the stream type,
so the search usually will not find the wanted stream.

This patch eliminates the useless stream_number variable and introduces a new
one, called real_stream_index to store the real stream index of the current
stream, no matter if we are looping through all the streams or only the streams
of a program.

Format detection and internal frame initialization is moved to a
separate init_image() function, which is called when all the tags have
been read, and so both BitsPerSample and SamplesPerPixel information
has been collected.

This fixes decoding of the file 11.tiff from roundup issue #1925.

Add an extra size validity check in asf_read_frame_header(). Without
this asf->packet_size_left may become negative, which triggers an
assertion failure later.
