aiongg 0a97679647 Images: harden the background decodes ...

- A panic anywhere in a background job, sizing and the wait at the gate
  included, marks the image bad. A guard takes the job off the busy
  list however it ends, and a thread that ends is counted out so
  another starts.
- Background decodes reserve their bytes where mip chooses the decode:
  the reduced JPEG estimate before a reduced decode (a JPEG without one
  goes to the full decode), the full peak before a full decode, nothing
  when a cached level is halved.
- A request turned away as recently decoded schedules one generation
  advance for when its window has passed, so its stand-in doesn't stay
  until the view changes. Emptying the cache (new colour settings,
  clear) starts a new epoch, and decodes into the old cache no longer
  count as recent.
- At most two full decodes are kept for zooming in; a newer one evicts
  the oldest.
- warm's planning runs under catch_unwind; a panic skips warming.
- Renderer::images_pending says whether the last render drew an image
  still decoding.

Regression tests use a test-only fault hook that panics inside the job
and inside warm's planning.
