Since the introduction of arena memory, these fields now have dynamic sizes that change between time steps depending on the number of active constraints. This breaks strict correspondence between joints and `efc_` rows.
Note that these fields can still be accessed directly as attributes on the `MjData` object.

1. Links to the programming chapter were broken after 69c74f850e. They're now fixed with a redirect in readthedocs.io, but this commit updates them to the latest URL.
2. Most docs links should point to "stable" instead of "latest", since most users will want the docs for the released version, not the upcoming version. The exceptions are the programming chapter, and instructions for building the Python bindings from source.

Also allow a `Callable[[], [MjModel, MjData]]` to be provided as an argument to `launch` instead of a fixed MjModel/MjData instance. This allows users to customise the behaviour of the Reload button.

Since upgrading to Clang 15, abseil fails to build, because of abseil/abseil-cpp#1201.

The GIL bug was introduced in ec6ea6a69e and is resolved by decrementing the refcount before returning from MjWrapperLookup.

- Added new `cable` composite type:
* The `initial` parameter specifies the joint at the starting boundary: `free`, `ball`, or `none`.
* The boundary bodies are exposed with the names:`B_left` and `B_right`.
* The vertex initial positions can be specified directly in the XML with the parameter `vertex`.
* The orientation of the body frame **is** the orientation of the material frame of the curve.
- Added new `cable` passive force plugin:
* Twist and bending stiffness can be set separately with the parameters `twist` and `bend`.
* The stress-free configuration can be set to be the initial one or flat with the flag `flat`.
* New cable example showing the formation of plectoneme.
* New coil example.
* New belt example showing interaction between twist and anisotropy.
* Added test using cantilever exact solution.

- 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.
