merge: let the user choose to merge, keep local or keep remote subrepo revisions
When a subrepo has changed on the local and remote revisions, prompt the user
whether it wants to merge those subrepo revisions, keep the local revision or
keep the remote revision.
Up until now mercurial would always perform a merge on a subrepo that had
changed on the local and the remote revisions. This is often inconvenient. For
example:
- You may want to perform the actual subrepo merge after you have merged the
parent subrepo files.
- Some subrepos may be considered "read only", in the sense that you are not
supposed to add new revisions to them. In those cases "merging a subrepo" means
choosing which _existing_ revision you want to use on the merged revision. This
is often the case for subrepos that contain binary dependencies (such as DLLs,
etc).
This new prompt makes mercurial better cope with those common scenarios.
Notes:
- The default behavior (which is the one that is used when ui is not
interactive) remains unchanged (i.e. merge is the default action).
- This prompt will be shown even if the ui --tool flag is set.
- I don't know of a way to test the "keep local" and "keep remote" options (i.e.
to force the test to choose those options).

Check that deep archive works with largefiles (which overrides hgsubrepo impl)
This also tests the repo.ui regression in 43fb170a23bd, and that lf subrepo
subrepos are archived properly.
Note that add --large through a subrepo currently adds the file as a normal file
