This change enables attaching images to the style with batches and
avoids massive re-allocations. Thus, it improves UI performance
especially at start-up time.
New setPrefetchZoomDelta(optional<uint8_t> delta) method allow overriding
default tile prefetch setting that is defined by the Map instance. The
method can be moved to generic style specification if found to be useful
for gl-js engine.
- Generate style code for 'line-sort-key' and 'symbol-sort-key'
- Add new layout properties to FillLayer::Impl, FillBucket, and FillLayerFactory
- Fix consistency of paint and layout properties type alias usage in FillBucket, LineBucket

- Enable node render tests for fill-sort-key and line-sort-key
- Fix FillBucket test construction
- Prefer emplace_back to push_back for PatternFeature container
- Fix buggy static_cast for PatternFeature indices
- Maintain sort of features as they are created
- Switch pattern layout features container to list from vector for better insert performance
- Fix formatting expected by sanity check
- Use subclass PatternLayoutSorted to work around lack of template functions
- Fix to retain source order for features with equivalent sort keys during sorting
- [core] Fix clang-format

Composing tiles from the GeoJSON features is an expensive
operation that might block UI thread on updating the `GeoJsonSource`
with the new data.
This change moves tile composing to the background thread and thus
unblocks the UI thread.
The output of Layer::getProperty is a mapbox::base::Value which is
equivalent to JSON. When setting the value of an enum property via JSON
its value would be a string, so it would be natural to return a string
too.
Also, the numbers generated depend on the enum definition. They are not
part of the style spec.
