Does not work for Julia mode, neither with block and bytecode.

Note: in DLL mode, the number of temporary terms in no longer given in the
‘ntt’ symbol; it must be computed using ‘M_.dynamic_tmp_nbr’.

add JSON output for plot_shock_decomposition, realtime_shock_decomposition, and initial_condition_decomposition

macroprocessor: fix bug: when macro variables were defined on the command line the resulting .mod file had newlines inserted at the top, resulting in incorrect line numbers when errors were encountered

In other words, allow newlines before these options

Before this commit, a dynare call such as
```
dynare <<mod file>> -Db=“A” -Da=@{b}
```
would not expand the value of `b` in `a` whereas
```
dynare <<mod file>> -Da=“A” -Db=@{a}
```
would expand the value of `a` into `b` because the arguments were stored in a map which printed the `@#define` statements in the .mod file in alphabetic order.

Use ReplaceShorterLiterals option to enforce replacement of all strings.

By the way, fix bug in detection of duplicate elements.

This is more elegant, and makes it easier to distinguish them from integer
options.

This reverts commit 21d42e60.

Add in M_ a list of exogenous variables that needs to be excluded if the model is not used for estimation.

Here, emplace() and insert() are not interchangeable because this is a std::set of
std::vector<int>, and we really want the initializer-list constructor of
std::vector (and not the two int's constructor).

Fixes the test deterministic_simulations/lola_solve_one_boundary.mod
