Those const data members are simply made public.

Now both x+(-y) and (-x)+y are simplified using a minus operator.

Also simplify some code using std::swap().

Incidentally, this fixes an issue in DataTree::operator=(), where this would
cause to the copy to have a different number of nodes than the original.

New options "mexext" and "matlabroot" are introduced, so that the preprocessor
knows where to find MATLAB and which architecture to compile for.

Only recent gcc is now supported. A set of optimization flags is used so that
compilation goes reasonably fast on large models.

Consequently, options "msvc", "mingw" and "cygwin" have been removed.

Introducing a new DataTree::getVariable() const method was necessary in the process.

In particular, it is necessary to turn back DataTree::AddVariable() into a
non-virtual method, because it is called from DataTree's constructor. Enforcing
the absence of leads/lags is now done using a new boolean DataTree::is_static.

Take advantage of the new copy constructor for handling
PlannerObjectiveStatement more elegantly.

Unfortunately it is not possible to implement *move* constructor / assigment
operators, because the reference ExprNode::datatree is not mutable.

The syntax makes clearer the distinction between a function call and an
initialization. Also, it prevents bugs due to implicit type conversions.

Closes: Dynare/dynare#1315

- BTW, store them in a std::vector rather than std::list

- incidentally, fix issue in VariableNode::removeTrendLeadLag where expression
  sharing was possibly violated when creating a new VariableNode

Given a previously declared var_model, the var_expectation_model statement is
used to declare a way of forming expectations with this VAR (possibly using a
finite or infinite discounted sum). The var_expectation operator now takes a
single argument, the name of the var_expectation_model.

For the moment, this only works when the var_model is using equations
explicitly declared in the model block.

- M and MEX files are now under +${MODELNAME}/
- bytecode and C source now under ${MODELNAME}/model/
