Patch 1-3 are from Luiz, added Markus's comments, discussion could be found
here:
http://lists.nongnu.org/archive/html/qemu-devel/2012-07/msg02716.html
Patch 3 was changed according Paolo's comments.
Patch 4-5: because qemu_opts_create can not fail while id is null, so create
function qemu_opts_create_nofail and use it.
Patch 6: create function qemu_opt_set_number, like qemu_opt_set_bool.
Patch 7: add def_value and use it in qemu_opts_print.
Patch 8: Create functions to pair with QEMUOptionParameter parser.
Patch 9: Use QemuOpts parser in Block.
Patch 10: Remove QEMUOptionParameter parser related code.
Patches 1 - 6 have been merged into block branch, so only patches 8 to 10
are included.
v7->v8)
1) print "elements => accept any params" while opts_accepts_any() ==
true.
2) since def_print_str is the default value if an option isn't set,
so rename it to def_value_str.
3) rebase to upstream source tree.
4) add gluster.c, raw-win32.c, and rbd.c.
v6->v7:
1) Fix typo: enouth->enough.
2) use osdep.h:stringify(), not redefining new macro.
3) preserve TODO comment.
4) fix typo: BLOCK_OPT_ENCRYPT->BLOCK_OPT_STATIC.
5) initialize disk_type even when opts is NULL.
v5->v6:
1) allocate enough space in append_opts_list function.
2) judge if opts == NULL in block layer create functions.
3) use bdrv_create_file(filename, NULL) in qcow_create funtion.
4) made more readable while using qemu_opt_get_number funtion.
v4->v5:
1) Rewrite qemu_opts_create_nofail function based on Peter Maydell's comments.
2) Use g_strdup_printf in qemu_opt_set_number.
3) Rewrite qemu_opts_print.
4) .bdrv_create_options returns pointer directly. Fix a bug about "encryption".
5) Check qemu_opt_get_number in raw-posix.c.
v3->v4:
1) Rebased to the newest source tree.
2) Remove redundant "#include "block-cache.h"
3) Other small changes.
v2->v3:
1) rewrite qemu_opt_set_bool and qemu_opt_set_number according Paolo's coments.
2) split patches to make review easier.
v1->v2:
1) add Luiz's patches.
2) create qemu_opt_set_number() and qemu_opts_create_nofail() functions.
3) add QemuOptsList map to drivers.
4) use original opts parser, not creating new ones.
5) fix other bugs.

qemu_opts_print has no user now, so can re-write the function safely.
qemu_opts_print will be used while using "qemu-img create", it will
produce the same output as previous code.
The behavior of this function has changed:
1. Print every possible option, whether a value has been set or not.
2. Option descriptors may provide a default value.
3. Print to stdout instead of stderr.
Previously the behavior was to print every option that has been set.
Options that have not been set would be skipped.
v7->v8:
1) print "elements => accept any params" while opts_accepts_any() ==
true.
2) since def_print_str is the default value if an option isn't set,
so rename it to def_value_str.

This patch will use QemuOpts related functions in block layer, add
a member bdrv_create_options to BlockDriver struct, it will return
a QemuOptsList pointer, which includes the image format's create
options.
And create options's primary consumer is block creating related functions,
so modify them together.
v7->v8)
1) rebase to upstream source tree.
2) add gluster.c, raw-win32.c, and rbd.c.
v6->v7:
1) use osdep.h:stringify(), not redefining new macro.
2) preserve TODO comment.
3) fix typo. BLOCK_OPT_ENCRYPT->BLOCK_OPT_STATIC.
4) initialize disk_type even when opts is NULL.
v5->v6:
1) judge if opts == NULL in block layer create functions.
2) use bdrv_create_file(filename, NULL) in qcow_create and cow_create funtion.
3) made more readable while using qemu_opt_get_number.
