Share how a ref's diff endpoints are derived

Browse Source 
The commit files context works out the two ends to diff from the ref (or
range of refs) it was entered for. The panels that hold those refs
themselves — commits, sub-commits, stash, reflog — are about to need the
same two ends, to hand out the diff behind what they render into the
focused main view. Pull the derivation out of the context so they can ask
for it rather than each spelling out the parent-of-from rule again.
