[Qemu-devel] [PATCH v24 11/31] qemu_opts_print: change fprintf stderr to printf

[Chunyan Liu <cyliu@suse.com>]

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)
