Make sure that plugin state is also restored after finite-difference calculations.

Before this change, loading a truncated MJB file would crash with mjERROR. After this change it will just return NULL.

- Fixed bug in timing of kinematics, was under-reported.
- Moved timing of inertia and collision into respective functions, in preparation for multi-threading.
- Detailed profiling in `testspeed` is always on, removed command-line flag.
- Improved `testspeed` self-documentation.

This solves the texture rendering issue with the Rubik's cube. The texture were specified with respect to the incorrect frame, so a default rotation of (0, 0, pi/2) is now applied to the model file.

Renamed `mjModel.eq_active` to `mjModel.eq_active0`, which now has the semantic of "initial value of `mjData.eq_active`".
Fixes#876.

1) protect mj_arenaAllocBytes with mutexes
2) create shards for each thread in the stack and update mj_stackAllocBytes to allocate memory within each shard for a given thread

- mjTIMER_ACCELERATION is not very useful, it's usually very tiny (0.5% for humanoid, 1% for 22humanoids). It basically times a single call to `mj_solveM`.
- Added `mjTIMER_ADVANCE` to time `mj_Euler` and `mj_implicit` (which can be significant).
- Moved `mj_transmission` to `mjTIMER_KINEMATICS` where it belongs (and used to be).

- See public description below.
- Stopped incrementing the iteration count in saveStats().
- `sizeof(mjSolverStat) == 40`, so this ends up costing 160KB, up from 40KB.
BEGIN_PUBLIC
Changed the size of `mjData.solver`, the structure used to collect solver diagnostic information. The array is now of length `mjNISLAND * mjNSOLVER`, where each row of length `mjNSOLVER` contains separate solver statistics for each constraint island. Until solver islanding is implemented, only row 0 is used.
- The new constant `mjNISLAND` is set to 20.
- `mjNSOLVER` is reduced from 1000 to 200.
- Added `mjData.solver_nisland`, the number of islands for which the solver ran.
- `mjData.solver_niter` (renamed from mjData.solver_iter) and `mjData.solver_nnz` are now integer vectors of length `mjNISLAND`.

The SDF is defined in the `geom` frame. Using a mesh changes this frame so the inverse transformation is needed. So far the full `geom_pos` and `geom_quat` were used, which possibly contained user transformation. This CL uses the new structures which only contain transformations due to mesh processing.

Also add asan instrumentation to detect stack frame leakages (i.e. `mj_markStack` without a corresponding `mj_freeStack` in the same caller function).
