Because at some point throwing exceptions from MEX files (with mexErrMsgTxt())
was not working under Windows 64-bit, we had designed a workaround to avoid
using exceptions.

Most MEX files were returning an error code as their first (or sometimes last)
argument, and that code would have to be checked from the MATLAB code.

Since this workaround is no longer needed, this commit removes it. As a
consequence, the interface of many MEX files is modified.

Add example mod-file for Ramsey and OSR

Closes #1645

Closes #1645

Documentation around change to ramsey

Closes #1678 and #1682

See merge request !1693

Moves common planner_objective command to front

Also clarifies restructures section on optimal policy and clarifies calling order of commands

[skip ci]

Automake actually provides such rules.

This reverts commit 6d516c39.

The method `desc_addname` adds arguments to the name of the node, and hence does not allow for line breaks. In the case of Dynare commands we don't run into a problem with this but we run into this problem with longer MATLAB/Octave commands.

For Dynare commands, we don't run into the problem with commands running over the page width as we use placeholders like `OPTIONS` since the order of the parameters passed to a command is irrelevant

For MATLAB/Octave commands, the order of parameters passed to a function is important, hence we cannot use a placeholder such as `OPTIONS`

closes #1688

- remove trailing whitespace
- replace tabs with spaces as per PEP guidelines

Closes: #1685

By the same token, remove unused support for Fortran 77.

Expand documentation of dynasave

Closes #1691

See merge request !1692

sim1.m: provide missing function input to nested function

See merge request !1691

Closes #1691

- `dynasave`: if a variable being saved was named `n` or `s`, the `eval` statements would break the code
- `dynasave`: use the `-struct` option to `save` to avoid `eval` statements
- `dynasave` and `dynatype`: do everything in 1 loop instead of 2
- `dynasave` and `dynatype`: use `strcmp` instead of `strfind`

- preprocessor update contains:
  - Partial reversion of global indentation of macro processor header files introduced in e2d5a83592634f0604d8c86409748cd2ec5906d2
  - Symbol List check pass: allow caller to specify the valid types of variables in a Symbol List
  - Allow `dynasave` and `dynatype` to support exogenous variables in their var_list

issue #1691

— Allow symbol list to accept auxiliary variables (#1355)
— Fixes around “det_cond_forecast” (preprocessor#39)
— Global reindentation

Also convert to Unix end-of-lines, and remove trailing whitespaces.

Finished identification order=1|2|3

See merge request !1689

Note that I still need to do a code clean up (provide some licenses for functions from other people) and to double check order=3. There is also much room for speed and memory improvement, but the code works fine for now. I will also provide more information to the merge request soon about the detailed changes for future reference.
