[PATCH v2 0/4] log --author-date-order

Not much changed in the first three patches since the edition from
last week.  A clean-up to clarify the toposort API, introduction of
priority queue API, and then its use in topological sort logic.

The final patch adds "log --author-date-order" to build on top of
them.

Adding tests to t4202 and/or t6012 is left as an exercise to readers.

Junio C Hamano (4):
  toposort: rename "lifo" field
  commit-queue: LIFO or priority queue of commits
  sort-in-topological-order: use commit-queue
  log: --author-date-order
