GitLab

This breaks the caching, because those patches have a recent timestamp (due to
git recloning).

This is a partial revert of 8a3938eb

Fixes #1622

– before executing the rule for unpacking the source, delete previously
  unpacked sources to avoid file overwrite (delete all versions so that the
  Gitlab cache does not grow too big)
— ensure that those rules are executed when a patch is modified

The MEX files are built out-of-tree (because we want to do them in parallel).
This would create a potential race condition if several builds want to create
the symlinks under mex/matlab/ or mex/octave/.

The solution is to disable those symlinks for out-of-tree builds.

Do not update OpenBLAS to 0.3.7, because that version fails to build when
LAPACKE is not requested.

The scripts are based the former “dynare-build” project. They have been
overhauled and simplified.

Building a Windows package (both installer and zip archive) is as easy as
running “make -C windows” (provided the right Debian packages are installed,
use the “windows/install-packages.sh” script for that purpose).

The layout of MEX files for Octave in the package has been
changed (mex/octave/win32/ and mex/octave/win64/ instead of mex/octave32/ and
mex/octave/), for consistency with MATLAB MEX.

imcforecast.m: Make code robust to 1 period

See merge request Dynare/dynare!1659

When using 1 period, the second dimension was a singleton that was removed as well by squeeze, resulting in a column vector when a row vector/matrix was expected. Fixes https://forum.dynare.org/t/problem-with-the-conditional-forecast-in-dynare-4-5-7/14385/2
