The try_restoration_tile function now works by calling
av1_loop_restoration_filter_unit rather than
av1_loop_restoration_filter_frame. This is rather more efficient,
because it only works on the unit in question, rather than memcpy-ing
the rest of the frame.

This patch also does a certain amount of rejigging for loop
restoration coefficients, grouping the information for a given
restoration unit into a structure called RestorationUnitInfo. The end
result is to completely dispense with the RestorationInternal
structure.

The copy_tile functions in restoration.c, together with those
functions that operate on a single stripe, have been changed so that
they take pointers to the top-left corner of the area on which they
should work, together with a width and height.

The same isn't true of av1_loop_restoration_filter_unit, which still
takes pointers to the top-left of the tile. This is because you
actually need the absolute position in the tile in order to do striped
loop restoration properly.

The earlier default was 25, which was reduced to 17 in
https://aomedia-review.googlesource.com/c/aom/+/28181

However, as temporal filtering may use 3 frames on either side by
default, we should have default lag in frames as 16 + 3 = 19.

The compression performance is exactly neutral between lag-in-frames of
25 and 17.

Let read_nz_map() etc. output to uint8_t*.

Temporarily introduced coeff_is_byte_flag as an argument of
get_nz_count() and get_nz_map_ctx() to handle different types of input
coefficients. It helps to not duplicate too many functions.
If possible, unify types to uint8_t* later.

We replace the division by shifts using already calculated 'x_scale_fp'
and 'y_scale_fp'.

That way, hardware can do it on-the-fly instead using a set of
programmable registers.

The OD_FDST_16() and OD_IDST_16() macros were written for use in the
 OD_FDCT_32_ASYM macro which took asymmetrically scaled input and
 after running an asymmetric butterfly step, passed it through to
 the 16-point Type-II DCT and 16-point Type-IV DST.
Because the DST implementations were never tested as stand alone
 transforms, some of the signs from the butterfly step ended up inside
 the DST macros.
These extra operations will be addressed in a follow up patch.
