Hi,

This is a compilation of patches I have to improve command line help
support. The first 2 patches have already been sent earlier, I
modified the first to fix an issue reported by Markus. The other
patches add support for -object help. A few preliminary patches for
QOM, to fix/improve some minor issues.

Marc-André Lureau (10):
  qemu-option: add help fallback to print the list of options
  qemu-option: improve qemu_opts_print_help() output
  qom/object: fix iterating properties over a class
  qom/object: register 'type' property as class property
  tests/qom-proplist: check duplicate "bv" property registration failed
  tests/qom-proplist: check properties are not listed multiple times
  tests/qom-proplist: check class properties iterator
  vl: handle -object ?
  hostmem: add some properties description
  vl: list user creatable propeties if '?' as argument
