Make kvazaar_encode consume one frame on each call.
...
- Replaces read_one_frame by encoder_feed_frame.
- Adds field "prepared" to encoderstate_t to indicate that
encoder_next_frame has been called.
- Input frames are read in the main function and passed to
encoder_encode.

Rename stats_done to frame_done in encoderstate.
...
The new field frame_done is set to zero when starting to encode a new
frame and reset to one when the encoded data has been written.

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.

Move OWF logic and CLI stuff out of encoder_compute_stats.
...
- CLI stuff is moved to either cli-module or to main function.
- OWF stuff is made more explicit by counting the frames instead of
communicating through encoder_state_t.stats_done.

Rename parameter encoder_state to state in all functions.
...
- It's so widely used that there isn't really need to emphasize that
it's the encoders state. Also, it isn't really the encoders state,
but encoding jobs state.

header added to the few that were missing one.

- Add encoder_state->global->cur_lambda_cost_sqrt.
- Use sqrt lambda for inter search and rough intra search.
- The effect on inter is around 10-20% bdrate. The effect on intra is smaller
and non-existent when --rd=2 is enabled, as the intra search refinement was
already done with SSD and correct lambda.
