Cleanup end IO handling
Abstract out the end IO handling, so that callers don't have to
keep track of completion details. Then we can make the
io_completion_data structure private to io_u, and just provide to

Change IO engine queuing
Instead of always pretending to be async, let the IO engines
return FIO_Q_COMPLETED or FIO_Q_QUEUED to signal async or
sync completions regardless of their nature. This cleans up
the queuing model quite a bit.
Also fixed a verification error spotted while doing this
transformation.
The main intent of this is to allow queuing more than 1 piece
of IO at the time, that will come in a later changeset.

usec_sleep() now takes into account the granularity of nanosleep().
Also stop using the remainder returned by nanosleep(), it doesn't
appear to always be accurate. Instead just check the elapsed time
manually.

[PATCH] Change O_DIRECT vs buffered setup
Change the default from O_DIRECT IO to normal buffered IO. That makes
more sense, as O_DIRECT is a special case and should be manually
enabled as such.
Do this by adding a option negate switch, so we don't need two sets
of parameters to control these options.

[PATCH] Change timeout to runtime and rearrange option entries
Runtime is a more descriptive name - the documentation is updated
as well, however the parsing has added an alias functionality to
support older names as well. So 'timeout' still works.
Also rearrange option entries, now they matter because the --cmdhelp
option will print them in order.
