Introduces StyleParser::Result being a std::tuple<Status, T>, where
StyleParser::Status is a boolean enumerator which improves readibility.

The invalid `TransformState::getAngle()` read comes from the following: the
storage for `TransformState` is the [bound parameter in this
callback](https://github.com/mapbox/mapbox-gl-native/blob/5e0775d276f9ea3652bae1
23c4e85cc05ae13bd5/src/mbgl/map/source.cpp#L292-292). The callback itself is
copied into various lambda bindings and eventually winds up as the [after
callback](https://github.com/mapbox/mapbox-gl-native/blob/5e0775d276f9ea3652bae1
23c4e85cc05ae13bd5/src/mbgl/map/tile_data.cpp#L89-89) for the worker task.
On the way out, `tileLoadingCompleteCallback` gets called via this callback
binding. It first does `emitTileLoaded`, which happens to cause [a _new_ work
request to be
queued](https://github.com/mapbox/mapbox-gl-native/blob/5e0775d276f9ea3652bae123
c4e85cc05ae13bd5/src/mbgl/map/source.cpp#L250-250). This cancels the
in-progress work request, [by nulling-out the `after`
callback](https://github.com/mapbox/mapbox-gl-native/blob/5e0775d276f9ea3652bae1
23c4e85cc05ae13bd5/src/mbgl/util/work_task.cpp#L34-34). But in fact, the after
callback is still executing. The next thing it does is [call
transformState.getAngle()](https://github.com/mapbox/mapbox-gl-native/blob/5e077
5d276f9ea3652bae123c4e85cc05ae13bd5/src/mbgl/map/source.cpp#L574), but the
transformState is now gone.

This eliminates a reference loop: VectorTileData holds StyleLayers which
hold StyleBuckets which held Sources which hold VectorTileDatas. This
breaks the StyleBucket -> Source link in favor of manually resolving the
reference where necessary.

Layers are added and removed dynamically on the Map thread when we use shape
annotations and we are iterating style.layers on the Worker thread without
any lock.
Now when we create a [Live|Vector]TileData at the Map thread we give it
a layers list (instead of the Style) and [Live|Vector]TileData will ultimately
make a copy of this list (on the Map thread, so no concurrency with
adding shape annotations).
The copy should be relatively cheap because we are using a shared pointer
for storing the layers on the list.

Use the callback provided for reporting the errors instead of throwing
an exception. The problem with the exception is it will happen on the
Map thread which makes it impossible to the user of our API to catch,
ultimately resulting in a crash.
In the scenario of not providing a callback, we just print an error.

This reverts commit 2435c1ad2603432186ee61eb4c423244a088bc51 (#1710), which needs to be revisited in light of #1655, which is a much higher priority at the moment.

The util::Thread will call the stop() method of the MapContext's RunLoop
which will wait for the pending tasks tied to it to complete.
If we have a request that is timeout'ing, this could mean a really long
wait. Instead, we now send a cleanup message that will reset all the
attributes first (canceling the pending requests) so the the MapContext
gets destructed quickly.

We start loading the resources at the moment we set the style, but we
set the callback for error notification at renderStill(), which happen
afterwards.
If some error occurs in this short window, it was never being notified.
Now we save the last error and we check after we set the callback.

After parsing a tile, it redoes placement for that tile if the angle has
changed since it started parsing. These redo calls were accidentally
done from the worker thread. Assigning the new work to `workRequest`
caused it to cancel itself.
Fix the problem by calling redoPlacement from the map thread.

The tile parsing is done in a worker thread and if it fails,
we set the tile state to "obsolete" and set an error message.
When the completion callback is fired, we check for the error
message and if it is set, we emit the error signal.
The trick here is the signal cannot be emitted directly from
the worker thread because that would violate data ownership rules.

The callback will be called when any of the resources requested
from the network failed to load.
There is not recovery implemented yet, so the closest thing to
reseting the Map object and reloading all the resources would
be setting a new style.
