Arttu Ylä-Outinen 024fedff57 Disable writing VPS when vps_period is negative. 
Turns vps_period in struct encoder_control_t into a signed value.
Negative values are interpreted as "never send parameter sets."

Arttu Ylä-Outinen d5f3778f72 Add function encoder_headers to API. 
This provides means for obtaining the VPS, SPS and PPS separately from
the rest of the bitstream.

  We can extend it later to make it a linked list like I was planning
  to do with the payload type.

Ari Koivula 9a3edce3fc Separate input and output from encoding. 
- Move image_t and pixel_t to the kvazaar.h API.
- Try and arrange things such that image_t can be used as input and
  output for encoding.
