prserv: import simplification

Simplify the importone() hook:
- to make it independent from the "history" mode which is
  client specific.
- remove the "history" parameter
- we want all values to be imported for binary
  reproducibility purposes.
- using the store_value() function (which warrants
  you don't save the same value twice and doesn't write
  when you're using a read-only server) is enough.
