When compiled with SQLITE_ALLOW_ROWID_IN_VIEW, rowid-in-view is on by default

Browse Source 
but can now be turned off using SQLITE_TESTCTRL_ROWID_IN_VIEW.  Without the
compile-time option, rowid-in-view is always off.

/* sqlite3_test_control(SQLITE_TESTCTRL_ROWID_IN_VIEW, int *pVal);
**
** Query or set the sqlite3Config.mNoVisibleRowid flag. Cases:
**
** *pVal==1 Allow ROWID in VIEWs
** *pVal==0 Disallow ROWID in VIEWs
** *pVal<0 No change
**
** In every case *pVal is written with 1 if ROWID is allowd in VIEWs and
** 0 if not. Changes to the setting only occur if SQLite is compiled
** with -DSQLITE_ALLOW_ROWID_IN_VIEW (hereafter: "SARIV"). With the
** "SARIV" compile-time option the default value for this setting is 1.
** Otherwise this setting defaults to 0. This setting may only be changed
** if SQLite is compiled with "SARIV". Hence, in the normal case when
** SQLite is compiled without "SARIV", this test-control is a no-op
** that always leaves *pVal set to 0.
**
** IMPORTANT: If you change this setting while a database connection
** is option, it is very important to run "PRAGMA writable_schema=RESET"
** afterwards in order to reparse all VIEW definitions in the schema.
