libx265: Fix 'braces around scalar initializer' warning

Now the first field is an integer and not an array.

fate: Add a PICT test

This stimulates the direct pixel mode in Quickdraw decoder.

lavf: Open PICT images with Quickdraw

Update the pictor test to use the pictor codec, as both formats share
the .pic file extension.

quickdraw: Support direct pixel blocks

Data is stored in separated components so rework decode_rle() to support
stepping and offsets.

quickdraw: Switch to greedy parsing

Quickdraw packs data as a series of codes that the application is supposed
to handle, but it does not define any order in which they might appear.
Since it's unfeasible to support *all* opcodes defined by the spec,
only handle well-known blocks containing video data and ignore any unknown
or unsupported ones.

Move palette loading and rle decoding to separate functions to resue them
in other blocks and drop format initialization in init since it can
support more formats than pal8.

Validate width and height.

quickdraw: Convert to bytestream2

Add appropriate error messages and reduce r, g, b variables scope.
