[PATCH 0/5] Parallel Checkout (part 2)

This is the next step in the parallel checkout implementation. An overview of the complete series can be seen at [1].

The last patch in this series adds a design doc, so it may help to review it first. Also, there is no need to have any familiarity with part-1, as this part doesn't have any semantic dependency with that.

This series is based on the merge of 'mt/parallel-checkout-part-1' and 'master', so that it can use the "brew cast" fix and the latest security fix (both from master), to run the tests. (The merge is textually clean, but it needs a small semantic fix: the '#include "entry.h"' addition in builtin/stash.c).

Parallel-checkout-specific tests will be added in part-3.
