First, the current logic is buggy, because mod_file->use_dll is undefined at
this point (mod_file having been deleted above).

More fundamentally, the preprocessor is now evolving into something to be used
without MATLAB/Octave, so this statement is now inaccurate in some use cases.

There is a new LINKOPTS variable which governs the list of symbols to be
exported, so we set it to an empty value to have all symbols exported.
Previously we were overloading the LDFLAGS which was containing the list of
exported symbols.

Fix comments in header of dynamic and static files

Columns and rows were confused

In the case where the external function computes itself its derivatives, the
TEF terms were not always created before being used, hence leading to a
preprocessor crash. This problem could only happen with ramsey_policy, because
otherwise the model does not contain derivatives of external functions.

This fixes the following bugs:

- 1st and 2nd ext fcn deriv nodes were incorrectly added to
  DataTree::external_function_node_map, because of the chaining of
  constructors.

- the following methods of FirstDerivExternalFunctionNode were not overloaded:
  toStatic(), buildSimilarExternalFunctionNode()

- the following methods of SecondDerivExternalFunctionNode were not overloaded:
  toStatic(), buildSimilarExternalFunctionNode(), compile(),
  compileExternalFunctionOutput()

Since the method was not implement, the method of the parent class was used.
This was leading to wrong results in the context of Ramsey Policy (basically
derivative operators on external functions were dropped from FOCs).

Fixes #598

Closes #624

- don't emit warnings if the steady_state_model block is not used
- the ramsey_policy check is spurious, there is another one deeper

Also rename DynareOutput.hh to FileOutputType.hh. Include the latter in dist
tarball, and add copyright/license header.

Closes #556

- allow recursive definitions (Closes #554)
- allow a variable to be defined twice, simply emit a warning (Ref #556)
