block: get rid of the BDRV_O_FILE flag
BDRV_O_FILE is only used to communicate between bdrv_file_open and bdrv_open.
It affects two things: first bdrv_open only searches for protocols using
find_protocol instead of all image formats and host drivers. We can easily
move that to the caller and pass the found driver to bdrv_open. Second
it is used to not force a read-write open of a snapshot file. But we never
use bdrv_file_open to open snapshots and this behaviour doesn't make sense
to start with.
qemu-io abused the BDRV_O_FILE for it's growable option, switch it to
using bdrv_file_open to make sure we only open files as growable were
we can actually support that.
This patch requires Kevin's "[PATCH] Replace calls of old bdrv_open" to
be applied first.
