NB: does not (yet) works with Occbin regime-specific equations.

preprocessor.tex: add slides on verbatim block and command line options

See merge request Dynare/preprocessor!94

Incidentally, makes tag names case-insensitive in “model_replace” and
“model_remove”, which is consistent with tag declarations.

Closes: #104

preprocessor.tex: further updates

See merge request Dynare/preprocessor!93

preprocessor.tex: modernizations and typo corrections

See merge request Dynare/preprocessor!92

It maps column indices in the Jacobian returned by bytecode MEX in evaluate
mode (which only contains nonzero columns, but also incorporate recursive
variables), into column indices in the sparse representation (which has 3×n
columns for two-boundaries blocks and n columns for one-boundary blocks).
Columns unused in the sparse representation are indicated by a zero.

It would return an incorrect result. This had no impact except for debugging
information.

When parsing the FSTPG{2,3} opcodes, the bytecode MEX internally constructs a
Jacobian with as many lines as feedback variables. But the preprocessor would
also output instructions for filling derivatives of equations corresponding to
recursive variables in the “evaluate” mode, thus leading to memory corruption
in the bytecode MEX.

The two are now compatible, even though the bytecode representation will not be
used.

This is cleaner than using exit() or assert() for that purpose.

Currently defaults to 0.

This should have been in commit 0169240f.

Those options do not internally behave as the usual command options (which have
a “o_*” rule), so it makes more sense to treat them differently.

This is a restoration of the behaviour that was present in 5.x.

It is already available as a class member.

CI: fix linker issue with XCode 15 and add job for Homebrew arm64

See merge request Dynare/preprocessor!90

XCode 15 (on Ventura and Sonoma) has a linker issue, see https://github.com/mesonbuild/meson/issues/12282, workaround is to use ld_classic
