[PATCH v3 0/4] log --author-date-order

The first one is unchanged. The second one was redone with Peff's help, and the other two patches have been adjusted for it.

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

Junio C Hamano (4):
  toposort: rename "lifo" field
  prio-queue: priority queue of pointers to structs
  sort-in-topological-order: use prio-queue
  log: --author-date-order
