As I'm a glutton for punishment I thought I'd have a go at fixing the
slowly growing number of record/replay bugs. The two fixes are:

 replay: stop us hanging in rr_wait_io_event
 chardev: force write all when recording replay logs

And the rest is various clean-ups and debugging aids. I don't know if
its worth pushing for 8.2 but it would certainly be nice to get some
review/testing to see if it solves issues for anyone else.

Alex.

Alex Bennée (11):
  tests/avocado: add a simple i386 replay kernel test
  tests/avocado: fix typo in replay_linux
  scripts/replay-dump: update to latest format
  scripts/replay_dump: track total number of instructions
  replay: remove host_clock_last
  replay: add proper kdoc for ReplayState
  replay: make has_unread_data a bool
  replay: introduce a central report point for sync errors
  replay: stop us hanging in rr_wait_io_event
  chardev: force write all when recording replay logs
  tests/avocado: remove skips from replay_kernel
