Leaks of `c/image/types.Image` = persistent HTTP connections

[Miloslav Trmač]

From a quick code grep, it seems to me that

common/libimage/image.go

Line 842 in 65a52f4

 remoteImg, err := remoteRef.NewImage(ctx, sys) 

(and, pedantically,

common/libimage/image.go

Line 94 in 65a52f4

 if _, err := ref.NewImage(context.Background(), nil); err != nil { 

, though that one is a no-op) should .Close() the returned types.Image.

That’s nowadays necessary to close potentially-persistent HTTP connections for c/image/docker .
