7bd3c89114 Add two new static mutexes, SQLITE_MUTEX_STATIC_APP1 and _APP2, for use by 
the application program.  First intended use is in test programs for the
memory allocation logic where one does not want to allocating a _FAST
or _RECURSIVE mutex since that would involve using the memory allocation
system under test.
