Add def_value_str (default value) to QemuOptDesc, to replace function of the
default value in QEMUOptionParameter.
Improve qemu_opts_get_* functions: if find opt, return opt->str; otherwise,
if desc->def_value_str is set, return desc->def_value_str; otherwise, return
input defval.
Improve qemu_opts_print: if option is set, print opt->str; otherwise, if
desc->def_value_str is set, also print it.

I still think you don't need to define the default value as a string to later
parse it, see what I mean https://lists.gnu.org/archive/html/qemu-devel/2014-03/msg04273.html
But I think we can live with it. See bellow, if you fix the issue you can add my Reviewed-by.

I see you removed this fprintf() in the commit afe65f5c92694d551aaebc128233b623e8665d5e
Please do this change in this commit and avoid breaking the block tests in
further commits.

This function won't be used until

It won't break block tests. The commit
afe65f5c92694d551aaebc128233b623e8665d5e
could be squashed with this commit directly. I split it into two steps just
to make
each patch easy to review, since in previous version, switching fprintf to
printf
in this patch was complained. But sure I can merge these two patches if you
still think it's better.

qemu_opt_del() already assumes that all QemuOpt instances contain
malloc'd name and value; but it had to cast away const because
opts_start_struct() was doing its own thing and using static storage
instead. By using the correct type and malloced strings everywhere, the
usage of this struct becomes clearer.

In later patch, qemu_opt_get_del functions will be added, they will
first get the option value, then call qemu_opt_del to remove the option
from opt list. To prepare for that purpose, move qemu_opt_del ahead first.

Add qemu_opt_get_del, qemu_opt_get_bool_del, qemu_opt_get_number_del and
qemu_opt_get_size_del to replace the same handling of QEMUOptionParamter
(get and delete).
Several drivers are coded to parse a known subset of options, then
remove them from the list before handing all remaining options to a
second driver for further option processing. get_*_del makes it easier
to retrieve a known option (or its default) and remove it from the list
all in one action.
Share common helper function:
For qemu_opt_get_bool/size/number, they and their get_*_del counterpart
could share most of the code except whether or not deleting the opt from
option list, so generate common helper functions.
For qemu_opt_get and qemu_opt_get_del, keep code duplication, since
1. qemu_opt_get_del returns malloc'd memory while qemu_opt_get returns
in-place memory
2. qemu_opt_get_del returns (char *), qemu_opt_get returns (const char *),
and could not change to (char *), since in one case, it will return
desc->def_value_str, which is (const char *).

Changes:
* Update description.
* After qemu_opt_get, delete all opt(s) related to the option instead of
delete the found opt only, so that it's really clean to pass left options
to second driver.

Add two temp conversion functions between QEMUOptionParameter to QemuOpts,
so that next patch can use it. It will simplify later patch for easier
review. And will be finally removed after all backend drivers switch to
QemuOpts.

Currently this function is not used anywhere. In later patches, it will
replace print_option_parameters. print_option_parameters uses printf,
to avoid print info changes after switching to QemuOpts, change
qemu_opts_print from fprintf stderr to printf to keep consistent.
Also to avoid print info changes, remove last printf and print size/number
with opt->value.uint instead of opt->str.
Signed-off-by: Chunyan Liu <cyliu@suse.com>

Changes:
* remove last printf
* add printf opt->value.uint for size/number type, keep same with
QEMUOptionParameter print. (e.g. 10M printed as 10485760)

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.

Changes:
* Use qemu_opt_find to judge if the option is set explicitly, replace
.assinged check in QEMUOptionParameter
* In qcow2_amend_options, use qemu_opt_get instead of qemu_opt_get_*_del

One extra change is to define QED_DEFAULT_CLUSTER_SIZE = 65536 instead
of 64 * 1024; because:
according to existing create_options, "cluster size" has default value =
QED_DEFAULT_CLUSTER_SIZE, after switching to create_opts, this has to be
stringized and set to .def_value_str. That is,
.def_value_str = stringify(QED_DEFAULT_CLUSTER_SIZE),
so the QED_DEFAULT_CLUSTER_SIZE could not be a expression.

Now only qemu_opts_append uses 'allocated' to indicate free memory.
For this function only, we can also let result list's (const char *)
members point to input list's members, only if the input list has
longer lifetime than result list. In current code, that is true.
So, we can remove the 'allocated' member from QemuOptsList definition
to keep code clean.

block/nfs.c is missing conversion. Have you tested your own patches?
A simple git am && config && make is enough to break the build.

Another case that's caused because "libnfs support no" and nfs.c is not
compiled. I'll update and check if there is other files missing. But is
there
any configure option that could enable all drivers?
For those changed backend drivers above, of course have been tested
"make && tests/qemu-iotests/check".
