added further documentation and fixed (!) the detection of used global object names on the LHS of assignments!

this allows name spaces on the LHS of assignments. It all works until insert-vardecs.c (5:ivd). There, the N_spids are turned into N_ids and the name spaces get lost again.
There is one catch though: annotatenamespace.c (3:ans) cannot properly find out whether a local definition of a global object refers to a different namespace.
The problem is that 3:ans runs before 3:uss which sucks in all used symbols at which point we could identify the objects within the symbols.
Unfortunately, 3:ans cannot easily be pushed behind 3:uss as 3:uss depends on gatherdependencies (3:gdp) which, in turn, requires (3:ans) :-(

One possible "solution" to this circular dependency would be to demand the user to always annotate the namespace on the LHS of assignments. Not nice but maybe acceptable,
at least for the time being.

So the key thing to do to progress this branch now is to make N_ids global object aware or create N_globobjs (<= 's' intentional!) which can sit within N_ids chains.
This has to happen when N_spids are replaced by N_ids in insert vardecs (5:ivd) and needs to be maintained
until all N_globobj (and then N_globobjs as well) are resolved in Resolving Global Objects/ Reference Parameters (5:rso and 5:rrp).

Hotfix 2302

Closes #2302

See merge request !187

fixed PMMskipPrf and SCS for and/or as exposed through issue 2308

See merge request sac-group/sac2c!186

added some comments in ct_prf as well

Hotfix 2303

Closes #2303

See merge request !184

completely rejigged the AUD WL code generation to properly support MOWLs

See merge request !183

now, it allows for
- multiple genarray + multiple propagate as long as the genarray shapes are all the same
- multiple fold + multiple propagate
- multiple propagate only
- one foldfix + multiple propagate

Also added tests for the base cases.

This should resolve the bug of issue #2298

resolve further aborts on missing module

See merge request !180

Fix issue #2297

Closes #2297

See merge request !182

added missing renaming in MOWL handling

See merge request !181

made the generated classes uniquely named added <file-name-strip> to the meta variables of the run script

this fixes the with-loop MOWL tests.

added the renaming, extended the explanation and streamlined the code modification.
also changed the default verbosity for the debug version to v2...
and added a few tests

one of the tests revealed that we, in some cases, do get self-assignment warnings from prop-obj -in/ out code generation.
I suppressed them on MAC for now. If they pop up on gcc based systems as well, we shall do the same there.

addendum to global objects: added tests

See merge request !179

added static declaration for global objects that are createed and used in programs locally

See merge request !178
