Most of the knobs that affect helper functions called from cmd_hash_object() were passed to them as parameters already, and the only effect of having them as file-scope statics was to make the reader wonder if the parameters are hiding the file-scope global values by accident. Adjust their initialisation and make them function-local variables.
The only exception was no_filters hash_stdin_paths() peeked from the file-scope global, which was converted to a parameter to the helper function.
