This patch contains the following possible cleanups:
- every file should #include the headers containing the prototypes for
  it's global functions
- make the following needlessly global variables static:
  - ivtv-driver.c: newi2c
  - ivtv-streams.c: struct ivtv_stream_info[]
- make the following needlessly global functions static:
  - ivtv-fileops.c: ivtv_stop_decoding()
  - ivtv-i2c.c: ivtv_i2c_id_addr()
- #if 0 the following unused global functions:
  - ivtv-i2c.c: ivtv_msp34xx()
  - ivtv-udma.c: ivtv_udma_setup()
  - ivtv-video.c: ivtv_encoder_enable()
- ivtv-driver.c: remove the unused EXPORT_SYMBOL's
