The /bin/ folder of all extra SR provided by the testnode are added to PATH.
SR must fixed either by moving executables or adding symlinks.

The testnode will stop looking at the parameter list of runTestSuite,
and --firefox_bin/--xvfb_bin are deprecated.

This is part of defining a generic and unique API between the testnode and
the tested software.

-  introduce External Function for Acquisition resolution to get over permissions
-  improve recursive TALES expression support
-  closely follow value resolution from ListBox
-  remove external method for default value resolution

- failure in callable does not throw error
- recursive tales support

This should fix bug 2071215-1637B3D
The fix was done by removing (commenting out) code which was making ERP5 possible to somehow use offline with the new UI.
Now the possibility is shrinking in favour of backward compatibility.

e.g. `activate(after_path=())` should ignore `after_path`

And move gadget global

Most properties of test suite and test suite repository were by mistake set with type "lines" instead
of strings. Due to this, constraints where not working (for checking missing properties). Also, workflow
was not properly set to check constraints. So at the end, most constraints were ignored.

Change properties from type lines to type string. Add test for constraitns. Add compatiblity code
to do transparent migration of existing tests suites and test suite repositories.

Remove obsolete properties and constraints.

This prepares for the removal of --firefox_bin and --xvfb_bin options. The
API between the testnode and the tested software must be exclusively generic.

generateMovementListForStockOptimisation was raising error when there was inventories.
The method was assuming that doing getObject() on an inventory line (from
getFutureInventoryList) was always returning a movement. But sometimes we get
the inventory itself. So do not use getVariationCategoryList, but use the variation_text
stored in the stock table.
