* Inline constrain and msb for cdef_filter_block
  This reduces its average time by around 42%.
* Inline round_shift for pred_directional and others
  This reduces its average time by around 10%.
* Inline sgrproj_sum_finish to its various callers
  It is at the lowest level of a hot call graph and almost trivial.
* Inline get_mv_rate in motion estimation
  It is almost trivial and called often.

Temporarily fixes #1115.

And keep the actual code as default trait

To compute the number of pixels available in the top-right and
bottom-left edges, get_intra_edges() received frame_w_in_b (MiCols) and
frame_h_in_b (MiRows) as parameters, initialized as follow:

    MiCols = 2 * ( ( FrameWidth + 7 ) >> 3 )
    MiRows = 2 * ( ( FrameHeight + 7 ) >> 3 )

<https://aomediacodec.github.io/av1-spec/#compute-image-size-function>

The sizes computed by get_intra_edges() were basically the frame
dimensions rounded up to the next multiple of 8, decimated:

    (MI_SIZE >> plane_cfg.xdec) * frame_w_in_b
    (MI_SIZE >> plane_cfg.ydec) * frame_h_in_b

But in Frame::new(), the luma plane dimensions are also initialized with
the frame dimensions rounded up to the next multiple of 8. Therefore, it
is equivalent to directly use the plane dimensions.

The function get_sad() was called with block width and block height
parameters swapped.

As a consequence, in tests, associate the precomputed SAD values to the
transposed block size.

This function is not needed in rust and it is mostly a convenience for
other languages. Instead move this chunk in the appropriate bindings.

* Fetch sccache binary release
* Use sccache for C and C++ dependencies
* Limit sccache size to 500M
* Use CI generic cache to store compiler cache

The functions sad_ssse3() and sad_sse2() only support u16 and u8
respectively, so they are not generic.

Make the caller pass the expected type.

This doesn't actually call the assembly functdions yet.

It acts a aligned memory wrapper.

Fixes #1101

Preliminary to use a different backing storage.

Apparently cbindgen has problems parsing them in the former rendition.

This reduces the odds of a Travis timeout.

Also, check out the v1.0.0-errata1 tag of libaom.

Many of the settings change nothing at the default speed.

Make cargo doc happier and make crav1e not depend on compiler
unstable feature.
