H A D023.out093ea232 Sun May 08 03:16:43 GMT 2016 Eric Blake <eblake@redhat.com> qemu-io: Allow unaligned access by default

There's no reason to require the user to specify a flag just so
they can pass in unaligned numbers. Keep 'read -p' and 'write -p'
as no-ops so that I don't have to hunt down and update all users
of qemu-io, but otherwise make their behavior default as 'read' and
'write'. Also fix 'write -z', 'readv', 'writev', 'writev',
'aio_read', 'aio_write', and 'aio_write -z'. For now, 'read -b',
'write -b', and 'write -c' still require alignment (and 'multiwrite',
but that's slated to die soon).

qemu-iotest 23 is updated to match, as the only test that was
previously explicitly expecting an error on an unaligned request.

H A D13637546ff2 Mon May 16 16:43:03 GMT 2016 Eric Blake <eblake@redhat.com> qemu-iotests: Fix regression in 136 on aio_read invalid

Commit 093ea232 removed the ability for aio_read and aio_write
to artificially inflate the invalid statistics counters for
block devices, since it no longer flags unaligned offset or
length. Add 'aio_read -i' and 'aio_write -i' to restore
the ability, and update test 136 to use it.
