[Qemu-devel] [PATCH v28 19/33] QemuOpts: export qemu_opt_find

[Chunyan Liu <cyliu@suse.com>]

Export qemu_opt_find for qcow2 driver using it.
After replacing QEMUOptionParameter with QemuOpts, qcow2 driver will
use qemu_opt_find to judge if an option is explicitly set, to replace
the usage of .assigned in QEMUOptionParameter.

Changes:
  * same as v27.
  * changes to v26:
    Following Eric's comment, split v26 qcow2.c patch into two:
    export qemu_opt_find first and then qcow2.c patch
