Before this change:
- User-modified values of `mjModel.stat.{meanmass, meaninertia}` would not be saved to XML.
- Non-user-modified values of `mjModel.stat.{meansize, extent, center}` would always get saved to XML.
After this change values are saved to XML only if provided by the user, either in the XML or by changing values in `mjModel` before saving.

The box-box collider sometimes outputs bad contact points which are far outside one of the two boxes. This happens at configurations which are very rare numerically, but rare configurations (e.g. perfect box alignment) are often induced by the designer and the physics, making them actually not-so-rare.
Since the box collision functions are very difficult to understand, we circumvent the issue by extending the post processing code to detect and remove such contacts.

Accept new attributes on the plugin/actuator tag:
- dyntype
- dynprm
- actlimited
- actrange
- actearly
This addresses some of the requests in #1098.

Also reduce slightly the resolution of the models to make comparing golden data more readable.

Added `option-actuatorgroupdisable` attribute and associated `mjOption.disableactuator` integer bitfield, used to disable sets of actuators at runtime according to their group.
- The first 6 actuator groups are toggleable in the `simulate` viewer.
- Minor refactor and cleanup of actuator documentation.

0. Keyframe was generated by simulating passively for 64 timesteps and then saving from `simulate`.
1. This makes forward.data much more informative. There are more contacts, velocities are not 0.
2. Added non-zero controls to forward.data.
3. 70 timesteps is a lot to integrate, things can change a lot. Since we now start at time = 0.128 = after 64 steps of passive simulation, we continue to integrate for only 6 timesteps.

Renamed `mjModel.eq_active` to `mjModel.eq_active0`, which now has the semantic of "initial value of `mjData.eq_active`".
Fixes#876.

1) protect mj_arenaAllocBytes with mutexes
2) create shards for each thread in the stack and update mj_stackAllocBytes to allocate memory within each shard for a given thread
