The current OptsVisitor flattens the whole structure, if there are same
named fields under different paths (like `in' and `out' in `Audiodev'),
the current visitor can't cope with them (for example setting
`frequency=44100' will set the in's frequency to 44100 and leave out's
frequency unspecified)

This is required to keep backward compatibility while applying the
proposed changes to OptsVisitor in the next commit.
Strictly speaking this change breaks QMP compatibility, but since this

Version 1 of the pc-*-2.5 machine class series was applied to the PCI
tree instead of v3 (which was rebased after the broken_reserved_end
patch by Igor was included).
This patch includes the missing hunks from v3, to make sure
broken_reserved_end is set at the right machine class.

This patch is still not applied upstream.
As there has been no discussion in over a year, I assume it is no longer
a problem and I'm going to mark it invalid. Please rep;ly if that is
not the case.
If it *is* still a problem, then we should go discuss on oftc#qemu.

The following changes since commit 684bb5770ec5d72a66620f64fc5d9672bf8d3509:
