util.sql: Add API to start an explicit write transaction This will be used in SQLite3 to BEGIN IMMEDIATE, which attempts to acquire write locks immediately instead of when the first write statement is started. Thus it would fail faster if the write lock is already taken. Normally that should not occur but e.g. prosodyctl could take it. Investigating whether something similar is sensible in PostgreSQL, MySQL is a future task.
