Subject: [PATCH] Fix the pager such that if the xOpen() message sends back the
 SQLITE_OPEN_MEMORY flag, the pager is opened in journal-mode MEMORY, even if
 compiled with SQLITE_OMIT_DESERIALIZE.  No changes to the logic as long as
 that OMIT flag is omitted.  We need to better document the behavior of xOpen
 to describe this.
