Alessio Quaglino f0608648cb Stricter swapping condition in mju_eig3.
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.

Yuval Tassa ee78b8f76b Added mjData.eq_active user input variable, for enabling/disabling the state of equality constraints.
Renamed `mjModel.eq_active` to `mjModel.eq_active0`, which now has the semantic of "initial value of `mjData.eq_active`".

Fixes #876.

Levi Burner c6961b77d7 Fallback for if GL_ARB_clip_control not available
If GL_ARB_clip_control not available then [znear, zfar] -> [1, -1] instead of [1, 0] in normalized device coordinates

Thus, Z is still reversed, but not shifted, clipping should still work properly, and conversion to window coordinates does not cause accuracy regression compared to non-reversed Z rendering.

Yuval Tassa 63fd23a934 Remove mjTIMER_ACCELERATION, add mjTIMER_ADVANCE.
- 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).

Yuval Tassa 86d8b912f4 Rejigged solver statistics in preparation for islanding.
- 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`.
