e45985b595 Fix a bug in the custom in-memory VFS used by fuzzcheck. This bug masks 
other bugs that should have caused some existing fuzzdata7.db entries to
fail, and so this fix is initially on a branch until those other bugs can
be repaired.

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.

42eb070729 Add the "PRAGMA legacy_alter_table=ON" command to enable the pre-3.25.0 
behavior of ALTER TABLE that does not modify the bodies of triggers or
views or the WHERE clause of a partial index.  Enable the legacy behavior
by default when running the xRename method of virtual tables.

eda079cd2c Combine the Expr.pTab and Expr.pWin fields into a union named "y". Add a new 
EP_WinFunc property that is only true if Expr.y.pWin is a valid pointer.
This reduces the size of the Expr object by 8 bytes, reduces the overall
amount of code, and shaves over 1 million cycles off of the speed test.
