b430701823 When a table is renamed using "ALTER TABLE RENAME TO", update any REFERENCES
clauses that refer to the table, unless "PRAGMA legacy_alter_table" is true
and "PRAGMA foreign_keys" is set to false (i.e. so that when "PRAGMA
legacy_alter_table" is set behaviour is still compatible with versions 3.24
and earlier).

f7f2a82aa0 On the first connection to a WAL-mode database that was not cleanly shut down
and contains a left-over -shm file, truncate the -shm file to 3 bytes instead
of to 0 bytes. Avoiding a truncation to 0 means that system monitoring tools
can better detect if a process illegitimately tries to truncate a -shm file.
Such a rogue process might think it is being helpful by cleaning up old files,
but there is a race condition that can cause damage to the database.
