  -----------
  tsan: define all fields for all mappings

Define all fields to 0 for all mappings.
This allows to write portable code and tests.
For all existing cases 0 values work out of the box
because we check if an address belongs to the range
and nothing belongs to [0, 0] range.

Depends on D107738.
