[v2,00/12] qdev: Make array properties user accessible again

Message

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 12 for details.

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
