Note that the unitary test in lyapunov_solver.m that checks sparse matrix input
had to be removed. Previously, this test was passing by chance (because the
sparse test matrices had actually no zero element, hence the internal double
float storage was the same as in the dense case). Now it consistently fails
with the additional checks in disclyap_fast MEX.
The code that computes ghx·yhat+ghu·u (both with and without pruning) was
making the implicit assumption that q⩽n, i.e. that the number of shocks is less
than or equal to the number of states. If q>n, it would try to read invalid
memory references in ghx and yhat, and would thus either crash or return dummy
results.

In its output, the MEX was returning values for all endogenous variables, but
it was used in a context where only the variables from oo_.dr.restrict_var_list
were expected (as is done with local_state_space_iteration_2 MEX).
This commit fixes this discrepancy, and also fixes the test that was checking
that both MEX are returning the same output.
Closes: #1768
It applies the approximated policy function to a set of particles, using
Dynare++ routines.
There is support for parallelization, using Dynare++ multithreading
model (itself based on C++11 threads; we don’t use OpenMP because it is
incompatible with MKL). For the time being, default to a single thread. This
should be later refined through empirical testing.
