Fix segfault in FuseStatic when body contains cameras or lights
...
FuseStatic deletes static (joint-less) bodies and reassigns their
children to the parent body. Geoms and sites were reassigned, but
cameras and lights were not, leaving dangling body pointers that
crash in mjCCamera::Compile() / mjCLight::Compile().
Add camera and light reassignment in FuseStatic and FuseReindex.

Dynamically allocate contact and efc_ arrays on a new memory arena.
...
- 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.
