Commit Message

Make sqlite3.Open thread safe

* sqlite3_open_v2 implicitly calls sqlite3_initialize
* sqlite3_initialize is not thread safe in the prologue
* concurrent calls of sqlite3.Open even on different files
  may trigger mutex initialization race and crash
* Fix: use go channel with a single message in it as a barrier
  letting only single-threaded sqlite3_open_v2 for the first time
* Reproducibility: very low, couple hours of concurrent sqlite3.Open calls
  trigger a single crash
