Change the names of the stream interface APIs to be of the form "_strm" instead of "_str". In other words, added an "m" to the end, to try to make it clear that we are talking about a "stream" and not a "string. check-in: 1f44bfdc user: drh tags: sessions

It also makes the code a little smaller. check-in: 83913515 user: drh tags: trunk
01:10
If an SQL function makes a recursive call to do an INSERT into the same database, make sure that the last_insert_rowid() for that INSERT is recorded. check-in: e93aecc0 user: drh tags: trunk
