[PATCH v3 00/36] cleanup qemu_init and make sense of command line processing

[Paolo Bonzini <pbonzini@redhat.com>]

Incompatible changes WRT 5.x:

- "-incoming defer" will not generate a MIGRATION event until
  the migrate-incoming command is sent

- the "preconfig" runstate is not reported anymore, and is replaced
  with "prelaunch"

Since the patches build on a bunch of more mechanical changes to
remove the ram_size and bios_name global variables, which affect
all targets, I have already placed the result in the for-6.0 branch of
my gitlab repository.  The branch has also passed CI already.

Thanks,

Paolo
