[PATCH v2 0/3] iolog: add version 3 with timestamp support

[Mohamad Gebai <mogeb@fb.com>]

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.

  iolog: add version 3 to support timestamp-based replay
  iolog: add iolog_write for version 3
  iolog: update man page for version 3
