— block decomposition: fix computation of recursive variables with mfs>0
— fix segfault of notmpterms option with block decomposition

new option max_check_ahead_periods (renaming old undocumented option max_periods), that truncates the number of periods for which agents check ahead the regime (a sort of myopic behavior beyond max_check_ahead_periods),
the option is valid for simul, smoother and likelihood.

Explicitly specify that OCTAVE_VERSION is a builtin. Otherwise the call to
“exists” will look for a file, among other things, which takes a lot of time.

The implementation was relying on the fact that in M_.equations_tags, all
equations have a name tag and they appear in the order given by equation
numbers. There is no guarantee that this will always be the case, so use a more
robust approach.

By the way, improve the implementation of get_equation_name_by_number.

small bug fixes

See merge request Dynare/dynare!2093

accept periodic solution in simulations ONLY IF two regimes differ by one period, to avoid pathological solutions.

We also do not check for periodicity when check ahead periods have been increased endogenously, again to avoid mis-identified periodicity.

Any other type of periodicity, is flagged as non-convergence with error code 313 (infinite loop of solutions).

if max_periods is set to finite number, enforce algorithm to check ahead ONLY until max_periods (i.e. when we want agents to be myopic beyond some future period)

when performing stochastic simulations, check ahead periods may increase endogenously at some point for regimes very long in expectation. such longer check ahead periods may considerably slow down convergence in subsequent periods, so users may want to avoid this.

with smoother_redux, factor out definition of nk to reconstruct filtered variables, and use a local variable nk (so options_.nk may remain empty).
