If the user specifies the backing file format,
then when opening the backing file, there is no need
to probe the (backing file) image to figure out its format.
This follows my previous patches implementing bdrv_create2
which keeps (for qcow2 only) the backing file format
as a qcow2-extension

Rearrange code, help printout and docs so that they are in the same
(hopefully more logical) order for easier maintenance.
Add help and docs for undocumented options.
Reformat slightly for more consistent help output.
Add comments to encourage better synchronization in the future.
