Subject: [PATCH] Have the "crash" VFS used by the tcl tests (test6.c) handle
 SQLITE_FCNTL_SIZE_HINT internally, instead of passing it directly through to
 the underlying VFS. This is important if the crash VFS is simulating
 non-default device characteristics such as SQLITE_DEVCAP_SEQUENTIAL or
 ATOMIC.
