[Qemu-devel] [PATCH for-next 1/6] qemu-img: Move quiet into ImgConvertState

[Max Reitz <mreitz@redhat.com>]

Move img_convert()'s quiet flag into the ImgConvertState so it is
accessible by nested functions.  -q dictates that it suppresses anything
but errors, so if those functions want to emit warnings, they need to
query this flag first.  (There currently are no such warnings, but there
will be as of the next patch.)
