[Qemu-block] [PATCH v3 0/5] block: Don't compare strings in bdrv_reopen_prepare()

[Max Reitz]

bdrv_reopen_prepare() assumes that all BDS options are strings, which is
not necessarily correct. This series introduces a new qobject_is_equal()
function which can be used to test whether any options have changed,
independently of their type.


v3:
- Patch 1:
  - Fix copyright header [Markus]
  - Drop qobject.h include from qnull.c [Markus]
  - Replacing all QObject includes by qmp/types.h in target/i386/cpu.c
    became unnecessary due to 01b2ffcedd94ad7b42bc870e4c6936c87ad03429
    (kept R-b anyway, because v2 contained exactly the same change as
     that commit)
- Patch 2:
  - Move the code for QInt and QFloat to QNum
  - Write function descriptions in imperative mood [Markus]
  - Break comment lines after 70 characters [Markus]
  - Style changes [Markus]
- Patch 3: Add a comment on what will go wrong when using e.g. -blockdev
           and the qemu-io reopen command together [Markus]
- Patch 5: Added some test cases for qobject_is_equal() [Markus]
