Test app/script patches from Jan Nijtmans for cygwin. Add/replace many more sentinel arguments for TCL variadic functions which specifically need a NULL trailing argument. With this, 'make test' on cygwin runs to completion for me, with 134 of 329227 tests failing. MSC build fails the same 13 tests which fail for me in trunk.

** Specifically, this file tests the effect of errors while initializing
** the various pluggable sub-systems from within sqlite3_initialize().
** If an error occurs in sqlite3_initialize() the following should be
** true:
**
**   1) An error code is returned to the user, and
**   2) A subsequent call to sqlite3_shutdown() calls the shutdown method
**      of those subsystems that were initialized, and
**   3) A subsequent call to sqlite3_initialize() attempts to initialize
**      the remaining, uninitialized, subsystems.
