drh f0075cd2e4 New Windows makefile targets for common EXEs that omit the ".exe" suffix, so 
that when muscle memory kicks in and we type "make sqlite3" on windows, it
still works.

stephan b1bbff20a0 Revert the native impl of kvvfs's xOpen() (as distinct from the JS impl which the wasm build uses) to the historical db name restrictions of 'local' or 'session', failing with SQLITE_CANTOPEN if passed another name. [ec866b04d088e53b] overhauled support for kvvfs db names in JS but it turns out that the native impl still relies on those names in order to match journals to databases. Correct a related too-lenient assert() in the WASM pieces.
