89c76981fc heightfield: Better support for float/double data 
Previously, the heightfield constructor always assumed `PHY_FLOAT` meant
`btScalar`, contrary to documentation and other usages of `PHY_FLOAT`.

Adds new constructors that distinguish between `float` and `double`.
The legacy constructor is still there for backwards compatibility.

This allows the client to use `float` or `double` regardless of
`BT_USE_DOUBLE_PRECISION`.

Fix stack overflow in parsing URDF files in Bullet

Fix stack overflow in parsing URDF files in Bullet 
When reading response from the Bullet server after a "load URDF" command, the client code allocated and zeroed buffers for the data chunks with a "+1" to account for the terminating zero. This was when the buffer pointer was interpreted as a `char *`, so it meant "+ 1 byte".

When reading those buffers, however, the associated pointer was a `void *`, so reading `sizeof(void*)` (8 on my machine) bytes at a time. Therefore it was reading up to 7 bytes past the allocated (and zeroed) memory.

The change fixes that by changing the "+ 1" to "+ sizeof(void*)". At one place it also extends the zeroing to the final buffer position (missing "+ 1" in the original).

Fix a null dereference in UrdfParser 
When the parser sees no <inertial> tag inside a <deformable>, it logs an error but does not return false. So in the next step, a null pointer is dereferenced.

This can be tested with loading the following URDF:
```
<?xml version="1.0"?>
<robot name="rhythm_carrot_sticks">
  <deformable name="bag">
  </deformable>
</robot>
```
