Going forward, the version number at head will be kept one ahead of the latest released version. The rationale behind this change is so that it is clear that the source code at head is more recent.

This change also requires user scripts to explicitly synchronize changes to physics state to the viewer. The Simulate class was reconfigured so that certain UI events are handled during this sync operation, outside of the render loop on the main thread. These correspond to operations that require access to the full mjModel/mjData.
To support other, more interactive operations (e.g. camera movements), a new mjvSceneState struct is introduced which captures only the portion of the physics state required for scene re-rendering. The mjvSceneState is updated from mjModel/mjData during the viewer sync operation, and is significantly cheaper than a full mj_copyModel and mj_copyData.

Add -Wgnu-empty-initializer to Clang builds to catch this issue in the future. Initialising arrays with empty braces is not part of the C standard and fails on MSVC. This commit should catch the issue earlier by detecting it in Clang.

The bug was introduced in 2f0fb1e4ef. The glfwSwapBuffers call should occur on the main UI thread, not the CoreVideo DisplayLink thread.

- Before this change, the y-axis scale had only one digit, leading to user confusion. Small changes in senor values could appear as if the values remained at the nearest integer value, while in fact the y-axis itself was changing, but this was not evident in the GUI due to the reduced precision.
- Fixes#719.

Note that The GLFW adapter currently assumes that a GPU is always present, so this new code path is never reached at the moment.

Change atomic_bool to atomic_int to make sure that the compiler will try the best to
generate machine code, instead of relying on an external atomic library
Current users only get a cryptic "Illegal instruction" crash.

- Memory heuristic rounds up to the nearest MB.
- `simulate` reports total memory currently allocated in the info box.
- All example models use `<size memory/>` rather than legacy attributes.
- Regenerated `example_saved.xml` and reformatted original model in [overview chapter](https://mujoco.readthedocs.io/en/latest/overview.html?#examples).
- `<size>` top-level section does not get written if empty.

- Add private function `mj_arenaAlloc`. This is used internally to allocate memory from the arena.
- Add private function `mj_nefc` to count constraints. This function returns a tight upper bound on `d->nefc`. The number of counted constraints can be slightly bigger than exact `d->nefc` in the case of constraints with empty Jacobian, as when placing a frictional tendon between two world sites.
- Add new `memory` attribute to the `size` XML element for specification of arena memory size. This attribute is mutually exclusive with `nstack` and `njmax` specifications, which are now deprecated (but left around for the time being for legacy compatibility).
- Move `d->stack` to the end of the new arena space. The stack now grows in reverse from the end.
