[Qemu-devel] [RFC v2 0/7] replace QEMUOptionParameter with QemuOpts parser

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

This is still a RFC, I cut some block image formats to simplify
the exploring.

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 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: remove QEMUOptionParameter and use QemuOpts parser.

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 (7):
  qemu-option: qemu_opt_set_bool(): fix code duplication
  qemu-option: opt_set(): split it up into more functions
  qemu-option: qemu_opts_validate(): fix duplicated code
  introduce qemu_opts_create_nofail function
  use qemu_opts_create_nofail
  create new function: qemu_opt_set_number
  remove QEMUOptionParameter
