No longer automatically add M-file substitutes for missing MEX files

However, keep the substitutes under matlab/missing/mex/, so that they can be
manually added should the need arise.

-Dynamic Loadable Libraries
-──────────────────────────
-
-For better performance, some parts of Dynare are written in the C++ language,
-which is faster than standard M-files. These parts are compiled and distributed
-as dynamic loadable libraries (DLL), located in the 'mex' subdirectory of your
-Dynare installation.
-
-If the DLL are correctly detected by MATLAB® or Octave, the following should
-be displayed when you launch Dynare:
-
-  Configuring Dynare ...
-  [mex] Generalized QZ.
-  [mex] Sylvester equation solution.
-  [mex] Kronecker products.
-  [mex] Sparse kronecker products.
-  [mex] Local state space iteration (second order).
-  [mex] Bytecode evaluation.
-  [mex] k-order perturbation solver.
-  [mex] k-order solution simulation.
-  [mex] Quasi Monte-Carlo sequence (Sobol).
-
-On the contrary, if DLL are not detected, Dynare will fallback on
-slower alternatives written in M-files (only for some of the DLLs),
-and display the following:
-
-  Configuring Dynare ...
-  [m]   Generalized QZ.
-  [m]   Sylvester equation solution.
-  [m]   Kronecker products.
-  [m]   Sparse kronecker products.
-  [m]   Local state space iteration (second order).
-  [no]  Bytecode evaluation.
-  [no]  k-order perturbation solver.
-  [no]  k-order solution simulation.
-  [no]  Quasi Monte-Carlo sequence (Sobol).
-
-In this last case, Dynare will run correctly on the basic features,
-but with suboptimal speed, and some features will be missing. There
-could be several reasons for MATLAB® or Octave failing to detect
-the DLL:
-
-— Your path settings may be wrong. Make sure that the ‘matlab’ subdirectory of
-  your Dynare installation is the only Dynare directory present in the path
-  variable.
-
-— Your MATLAB® or Octave version may be incompatible with the provided
-  binaries.
-
-— You may have a custom M-file in your search path with the same name than a
-  DLL, therefore overriding it.
