264bcad69a Avoid integer overflows (a) when dealing with zeroblob(N) calls when 2*N is larger than 2^31, and (b) in fts5 when a corrupt record is close to 2^31 bytes in size. Both of these require special builds with SQLITE_MAX_LENGTH set to a non-default value.

1d574d3d71 Remove the memvfs.c extension, to prevent it from being misused. 
See [forum:/forumpost/91811439aa|forum post 91811439aa] for the complaint
that prompted me to take down this demonstration code.  I have other things
to do rather than argue about posts such as the foregoing, so it is easier
to just take the code down.  If you need this code, you can downloading older
check-ins.  The beauty of DAG-based version control systems like Fossil
(and Git) is that nothing is ever lost; it is just stops appearing on
trunk.
