block: Add driver-specific options for backing files

Options starting in "backing." are passed to the backing file now. If
you don't need to specify the filename for the backing file, you can add
it on the command line instead of in the image file:

$ qemu-nbd -t /tmp/test.img...

curl: Use bdrv_open options instead of filename

As a bonus, going through the QemuOpts QEMU_OPT_SIZE parser for the
readahead option gives us proper error reporting that the previous use
of atoi() lacked.

gluster: Use bdrv_open options instead of filename

This is only to convert the internal interface that is used for passing
the "filename" to be parsed, but converting to actual fine grained
options is left for another day, as it doesn't look trivial.
