to prepare for having a long running odb helper sub-process handling the communication between Git and an external odb.
We introduce "odb.<name>.subprocesscommand" to make it possible to define such a sub-process, and we mark such odb helpers with the new 'script_mode' field set to 0.
Helpers defined using the existing "odb.<name>.scriptcommand" are marked with the 'script_mode' field set to 1.
Implementation of the different capabilities/instructions in the new (sub-)process mode is left for following commits.
