* cdef: pick strength based on quantizer

   PSNR | PSNR Cb | PSNR Cr | PSNR HVS |    SSIM | MS SSIM | CIEDE 2000
-0.3890 | -0.7035 | -1.2771 |  -0.1636 | -0.0987 | -0.0441 |    -0.1748

~4-6% faster encoding time for low QP.

This avoids a desync when e.g., CDEF bits == 2

Now that partition context is stored at 8x8 granularity, a different
constant needs to be used for above_coeff_context size.

Fixes #1386

Currently, it uses heap allocations to pass the returned slice to
C-land. This isn't much a perf hit, give the infrequent use (once
per frame), and is a lot simpler than having callers provide alloc
callbacks.

container format will use this information to build seek index.
This will make the mp4 seekable

In reality, "bits_per_frame" was "bits_per_tu", so we can rename it
 and just subtract a constant amount to cover the cost of each
 temporal delimiter.

Allows the user to run the second pass of a two-pass encode while
 simultaneously outputing a new first-pass stats file to use for
 a third and subsequent passes.
No change to the public API is required.

PUBLIC API CHANGE:
-Addition of EncoderStatus::NotReady
-Addition of Context::twopass_out()
-Addition of Context::twopass_bytes_needed()
-Addition of Context::twopass_in()

The per-frame data passed to update_state() does not include the
 temporal delimeter.

It requires the git cargo-c until it is released

Currently pinned to one pass only, since, as far as I know, this is
all rav1e currently supports.

Should support the frame reuse better.

And some documentation.

That chunk of code belongs here, it is not needed for rust code anyway.
Slightly adjust the documentation on error.
