faster image inspection

Vendor the latest HEAD in c/common to pull in changes for a faster
inspection of images.  Previously, only the size computation was
optional, now the one for the parent image is as well.

In many cases, the parent image is not needed but it takes around 10ms
on my local machine.  With this change, we cut off 10ms from many code
paths, most importantly, container creation.

[NO NEW TESTS NEEDED]
