[Qemu-devel] [PATCH V6 00/10] replace QEMUOptionParameter with QemuOpts parser

[Dong Xu Wang <wdongxu@linux.vnet.ibm.com>]

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.

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.

Dong Xu Wang (10):
  qemu-option: opt_set(): split it up into more functions
  qemu-option: qemu_opts_validate(): fix duplicated code
  qemu-option: qemu_opt_set_bool(): fix code duplication
  introduce qemu_opts_create_nofail function
  use qemu_opts_create_nofail
  create new function: qemu_opt_set_number
  add def_print_str and use it in qemu_opts_print.
  Create four opts list related functions
  Use QemuOpts support in block layer
  remove QEMUOptionParameter related functions and struct
