[PATCH v3 00/11] qdev: Make array properties user accessible again

[Kevin Wolf]

Array properties have been inaccessible since commit f3558b1b both on
the command line and in QMP. This series reworks them so that they are
made accessible again in these external interfaces, this time as JSON
lists. See patch 11 for details.

v3:
- Rebased, patch 1 was already merged in the context of another series
- malloc() the elements for the temporary list in set_prop_array().
  Having the value directly in GenericList.padding resulted in bad
  alignment for some property types on 32 bit platforms.

v2:
- Patch 1: Use unsigned instead of uint32_t
- Patch 9: Fixed build error
- Patch 11: Split into a separate patch to clarify the intention
- Patch 12:
  * Improved the commit message
  * Document and statically assert alignment requirements for array
    elements (the static assertion turned out to be much uglier than I
    had hoped, but it is what it is)
  * Replace UB in pointer arithmetics with uintptr_t calculations
  * Fix properties without a .release callback
  * Check array size for integer overflow
  * Call visit_check_list() even for output visitors
- Coding style changes
