pass M_, options_, oo_ as arguments to stoch_simul, simult_, discretionary_policy. closes dynare#1197

The globs were not expanded because pathname expansion does not occur in a
variable assignment. Use a Bash array instead.

This means we now require GCC 8.

Boost filesystem library is no longer needed.

They're no longer needed now that the date is part of the snapshot filename.
Also, updating them from the CI was creating a discrepancy with the snapshots
listed on the website (until the latter was rebuilt).

It now also deletes the old snapshots. It has been moved in
/home/gitlab-runner/ on eris.

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

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.
