[RFC PATCH 00/19] object store: grafts and shallow.

This applies on top of sb/object-store-alloc[1], and is the next part of the object store series.

I think we're getting close to actually being done in the object store series, as the next series to build on top of this will convert the lookup_{object, commit, ...} functions.

However I marked this series as RFC, as I expect heavy conflicts with the code base. sb/object-store-alloc builds on an older base of the code base and there have been some series that will conflict with this one. For example the patch to migrate path functions into a repository world will collide with one of Dschos series as he added another path helper function there. I am happy to reroll on top of that, but for now I chose sb/object-store-alloc to keep the momentum in the object-store series'.

There is another object store series that is not part of the critical path: There is a mem leak in the pack files stored in the raw object store. Upon free'ing the repository we do not free its pack files. We cannot free the packfiles, as otherwise the bitmap code would have dangling pointers into packfiles that no longer exists, leading to segfaults. So we'll need to have an object store series covering the bitmap code. I have something local, which I'll send out shortly.

Thanks, Stefan
