Don't do bgp/solow-1 in Octave

See merge request !1780

Do not compute cholesky decomposition of H if the matrix has zeros on
the diagonal.

Also adds test cases

... Or add a new method if one is missing.

Because of a bug, Octave wrongly complains that matlab/+pac/+bgp/{get,set}.m
shadow built-in functions (see https://savannah.gnu.org/bugs/?46849).

We disable the warning as early as we can after running the dynare command.
However the warning will nevertheless appear two times in a given Octave
session (the first time when the addpath to Dynare is done, the second time
when the dynare command is run).

When merging the enterprise code, the dogleg subfunction was modified to
incorporate a call to decomposition(), which does not exist under Octave and
MATLAB < R2017b.

For those cases, we reinstate the old code (which uses a plain matrix right
divide).

That filename conflicts with Octave’s builtin example() function.

unique(…, 'stable') does not exist in Octave 5.

Method of Moments: use analytical Jacobian in gradient-based optimizers (GMM only)

New option analytic_jacobian for mode_compute 1, 3, and 13

The formulas are taken from commit c2acb4e30f7a99426a34dbdea26991459454c834 of
the homebrew-core repository.

The formulas were modified as follows:
— in the "bottle" do/end block, this line was added:
   root_url "https://homebrew.bintray.com/bottles"
— in the "bottle" do/end block for gcc, this line was added:
   cellar :any

The preprocessor has been updated accordingly.

Currently it is not applied consistently to all binaries we produce.

Moreover we do not really have a way to test support for older macOS versions.

If there are problems, we might reintroduce this flag later, but we will have
to it consistently across all binaries.

This reverts commit 1975e467.

This reverts commit 2acacf61.

This reverts commit 8d4a8095.

Adapt the manual accordingly.

Closes: #1600

- strip the new preprocessor binary
- include the new preprocessor binary in the .zip and .7z archives
- include the old (backward-compatible) preprocessor binary in the .exe installer

Does not work with the version of Sphinx used on our Gitlab runners.
