Andrew Chow	3bfa0fe125	Initialize and Shutdown sqlite3 globals ... sqlite3 recommends that sqlite3_initialize be called when the application starts, and sqlite3_shutdown when it stops. Since we don't always use sqlite3, we initialize it when a SQLiteDatabse is constructed (calling sqlite3_initialize after initialized is a no-op). We call sqlite3_shutdown when we see that there are no databases opened. The number of open databases is tracked by an atomic g_dbs_open.	2020-10-14 11:28:18 -04:00
