It seems that meson does not link libquadmath (which is needed by libgfortran).
When doing dynamic linking, this is not an issue since the dynamic linker loads
libquadmath recursively after loading libgfortran. But when doing static linking,
libquadmath needs to be explicitly linked.

Not yet clear at this point: why isn’t this needed under Linux and Windows?

Dynare++ is no longer distributed as a standalone binary.

Fix marginal linearization in the context of perfect_foresight_with_expectation_errors_solver with homotopy

If a solution corresponding to 100% of the shock can’t be found in the first
informational period, marginal linearization will be performed to extrapolate a
solution.

However, in subsequent informational periods, this extrapolated solution cannot
be used for the initial conditions of endogenous variables, because the initial
conditions are not a true solution of the nonlinear model. For those subsequent
informational periods, the correct approach is to compute the two solutions
needed for marginal linearization using as initial conditions the values
obtained in the same two solutions for the previous informational
periods (stored as oo_.deterministic_simulation.{sim1,sim2}).

Unfortunately it is not possible to enable it for all supported Octave
versions (which would have allowed us to remove the old codepath), because of
this bug: https://savannah.gnu.org/bugs/?64687

Incidentally, this means that the JSONlab submodule is no longer needed, so it
is removed in the present commit.

As a consequence, drop old uncrustify config file.

This replaces the old hack which was using a local Linux-specific symlink. Now,
the Dynare default is the same as in Sphinx, i.e. rely on a CDN for delivering
MathJax.

Adapt our CI accordingly to continue using MathJax from the Debian package
there (to avoid privacy issues related to the use of a CDN).
