Saran Tunyasuvunakool 077acb1c8f Revert test fixture name in user_{model,objects}_test.cc.
These were inadvertently renamed to XMLReaderTest by an overzealous auto-renamer in 58fd72f53d.

Saran Tunyasuvunakool 58fd72f53d 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.

Nimrod Gileadi a693a2d981 Don't infer limited attributes automatically by default.
This is an amendment to 4bfc2c0311.

Add an autolimits compiler option. When true, *limited will be inferred from the presence of the *range attributes.
When false, models where limited is not specified, and range is will fail to compile.
