Arttu Ylä-Outinen 6451df9a4f Move bitstream chunk definition to kvazaar.h. 
- Renames struct bitstream_chunk_t to kvz_data_chunk.
- Renames macro BITSTREAM_MEMORY_CHUNK_SIZE to KVZ_DATA_CHUNK_SIZE.
- Removes kvz_payload typedef.
- Adds function chunk_free(kvz_data_chunk *chunk) to kvazaar API.

Arttu Ylä-Outinen 25706af770 Add a function for moving bitstream data. 
Replaces calls to bitstream_append with bitstream_move where possible.

Arttu Ylä-Outinen 398f0c823b Replace memory bitstreams with linked lists. 
- Removes all bitstream types.
- Changes encoder_encode to return the encoded data as list of chunks.
- Moves writing of the encoded data to the main function.

Arttu Ylä-Outinen 4a7b86a43b Make g_exp_table statically allocated. 
Removes the need to free the table.

Ari Koivula fc58748ae8 Output bitstream through API. 
- Use the existing bitstream_t type to give access to the bitstream.
  We can extend it later to make it a linked list like I was planning
  to do with the payload type.
- The main encoder now also stores the bitstream in memory.

Ari Koivula d7383ccb25 Change license to LGPL. 
- Everyone who has contributed code to the project has been asked to license
  their contributions under LPGL and they have agreed.

- COPYING file changed to say LGPLv2.1 instead of GPLv2.

- GPL changed to LGPL in the header of every single file that a header and
  header added to the few that were missing one.

- Also.. Happy new year!

  require stdint.h.
- Includes required by the header have been moved from the .c to the header.
- Spaces have been added between includes to distinguish classes of includes.
