Zone import/prefill

Code seems okay but we need to sort out two things:

1. Tests need to be be trimmed because adding huge files will unnecessarily inflate Git repo and slow down everything. Please trim all test zones to couple lines, either valid or invalid.

2. Commit messages should explain reasons why the change was made instead of describing the change itself (that can be seen in the code anyway :-). Example: "zimport: checking return value of zi_state_parsing()" -> "zimport: avoid crash on zi_state_parsing() failure" etc.

Other than that it is good and I want to include it in release on Wednesday.
