This set of patches introduces version 3 of the iolog replay. This version adds support for timestamps on both iolog_read and iolog_write. The 'wait' action is no longer supported with version 3, as the same behavior can be achieved with timestamps, and it keeps the iolog file easier to follow. This could also allow to potentially deprecate the 'wait' action eventually. Changes from v1: * Add commit messages to #2 and #3, and fix the format of #1. * Store fio_gettime() in td->last_issue directly rather than memcpying to it in commit #1.
