cad052544c try to make vips_thread_shutdown() optional

e9ce212b62 make out of order read a fatal error 
For png and jpg, out of order must always be a fatal error, since you
can't read from a specific y position.

This was a g_assert() before which meant that this test was missing from
production builds. It's now always a fatal error.

of order enough to make vipspng free the read object early
