Not quite right. This needs to be:
# @help: #optional human readable text string, not suitable for parsing.
#
# @default: #optional string representation of the default used
# if the option is omitted (since 2.0).

NULL input; for opt_set, when set to an existing option, rewrite the option
with new value.

In qemu_opt_set functions, if desc doen't exist but opts_accepts_any is true, it
won't report error, but can still alloc an opt for the option and save it.
However, after that, when doing qemu_opt_get, this option could be found in opts
but opt->desc is NULL. This is correct, should not be treated as error.
This patch would fix vvfat issue after changing to QemuOpts.

Change block layer to support both QemuOpts and QEMUOptionParameter.
After this patch, it will change backend drivers one by one. At the end,
QEMUOptionParameter will be removed and only QemuOpts is kept.
