When several PCI bridges were in use, monitor command "info pci" would
enter into infinite loop. Buses behind the bridge were not discoverable
because secondary and subordinate bus numbers were not used properly.
Other buses were not found because bus search terminated on first miss.

This reverts commit 2ba6edf0.

The commit has two issues:

* When it runs from the monitor, e.g. "device_add e1000,?", it prints
  to stderr instead of the monitor.

* Help looks to callers just like failed device creation.  This makes
  main() exit unsuccessfully on "-device e1000,?".

We need to do this differently.

This reverts commit 922910ce.

The commit has four issues:

* When it runs from the monitor, e.g. "device_add e1000,mac=?", it
  prints to stderr instead of the monitor.

* Help looks to callers just like failed device creation.  This makes
  main() exit unsuccessfully on "-device e1000,mac=?".

* It has an undocumented side effect on -global: "-global e1000.mac=?"
  prints help, but only when we actually add an e1000 device.

* It does not work for properties that accept the value "?".

We need to do this differently.

Help was shoehorned into device creation, qdev_device_add().  Since
help doesn't create a device, it returns NULL, which looks to callers
just like failed device creation.  Monitor handler do_device_add()
doesn't care, but main() exits unsuccessfully.

Move help out of device creation, into new qdev_device_help().

Return the bitwise inclusive or of all return values instead of the
last call's value.  This lets you find out whether any of the calls
returned a non-zero value.

No functional change, as existing users either don't care for the
value, or pass non-zero abort_on_failure, which breaks the loop on the
first non-zero return value.
