Yuval Tassa c945247e7c Don't write limited and actuatorfrclimited attributes when "true" is not a valid value.
Saved XMLs are filled with
```
<joint type="free" limited="false" actuatorforcelimited="false"/>
```

but since these are hardcoded to "false" at compile time, there is no point in saving them to XML.

Alessio Quaglino 7cdf180641 Introduce trilinear flex parametrization.
These flexes use only 24 DOFs (3 per vertex of the bounding box), while colliding with the full high resolution mesh.

On an 8x8x8 cube, the performance using DOFs at all vertices is

```
 Simulation time      : 18.74 s
 Steps per second     : 533
 Realtime factor      : 0.53 x
 Time per step        : 1874.4 µs

 Contacts per step    : 114.88
 Constraints per step : 3322.51
 Degrees of freedom   : 1536
```

With the new implementation, it is the following:

```
 Simulation time      : 1.82 s
 Steps per second     : 5507
 Realtime factor      : 5.51 x
 Time per step        : 181.6 µs

 Contacts per step    : 38.84
 Constraints per step : 155.36
 Degrees of freedom   : 24
```

Alessio Quaglino 66faba9aa5 Avoid changing semantics of mjsPlugin.name across XML sections.
The `extension` section used to discard the plugin name and write the instance name in `plugin.name`, while all of the other sections wrote the instance name in `plugin.instance_name` and optionally the plugin name in `plugin.name` (via the function `OnePlugin`). Now all plugin names are in `plugin.plugin_name` and the instance is written in `plugin.name`, so that it is possible to lookup a plugin via its unique instance name.
