Fix the extension01.test script so that it works on windows.  Fix a 
harmless compiler warning in the fileio extension.
Add the ".eqp" dot-command to the ".help" output in the command-line shell.

Back out the unix VFS changes that seeks to avoid fstat() calls after an
unlink().  That change did not clear the problem on FuseFS.
Add an application ID for MBTiles tilesets.
Add the SQLITE_UNLINK_AFTER_CLOSE compile-time option.  If enabled, the
unlink of temporary files on unix is deferred until after the file is closed.
In the "wheretrace" logic (disabled for normal builds) expand the print width
of the flags field to be wide enough for all 17 bits.
