Ari Koivula 8ad7d2a714 Move interlacing stuff to libkvazaaar API
This moves the interlacing from CLI code to api->encoder_encode, in
order to make it possible to use field coding through the lib API.

The field order is now determined per frame, as FFmpeg gives it per
frame and it's signaled per frame.

As a side effect, the CLI also now prints info from frames instead of
fields. While we might want to extend the API in the future to allow
printing of more detailed information about fields, for now it's
more important that the CLI uses the real lib API.

PSNR calculation for interlaced frames disabled until we have a way to
avoid deinterlacing the frame when it's not necessary.

Arttu Ylä-Outinen 49677810b5 Rename config module to cfg.

generated by configure is included in global.h. Fixes problems with
large input files on 32-bit systems.

Arttu Ylä-Outinen 70b3e10e27 Fix a crash with owf=4, gop=8, frames=10.
A call to kvz_threadqueue_waitfor caused the tqj_bitstream_written field
of the previous encoder state to become a dangling pointer, subsequently
causing an assertion to fail. This would only occur when the encoder
state used for a new frame was not the last finished one.

Fixed by setting tqj_bitstream_written to NULL after the job is done and
removing unnecessary calls to kvz_threadqueue_waitfor.
