Find moves and copies between context c1 and c2 that are relevant

"copy" is a mapping from destination name -> source name,
where source is in c1 and destination is in c2 or vice-versa.
"movewithdir" is a mapping from source name -> destination name,
where the file at source present in one context but not the other
needs to be moved to destination by the merge process, because the
other context moved the directory it is in.
"diverge" is a mapping of source name -> list of destination names
for divergent renames.
"renamedelete" is a mapping of source name -> list of destination
names for files deleted in c1 that were renamed in c2 or vice-versa.

We have to re-setup the function building 'filectx' for each

detection. Moreover, having a proper '_ancestrycontext' setup ensures
the performance impact of this adjustment is kept limited. Without it,
each file could do a full dag traversal making the time complexity of
the operation explode (see issue4537).
This function exists here mostly to limit the impact on stable. Feel
free to refactor on default.
