The vmstate for isa_ipmi_kcs was referencing into the kcs structure,
instead create a kcs structure separate and use that.
There were also some issues in the state transfer. The inlen field
was not being transferred, so if a transaction was in process during
the transfer it would be messed up. And the use_irq field was
transferred, but that should come from the configuration.
To fix this, the new VMS_VSTRUCT macros are used so the exact
version of the structure can be specified, depending on what
version was being received. So an upgrade should work for KCS.

Instead of scanning IPMI devices from a fwinfo list, allow
the fwinfo to be fetched from the IPMI interface class.
Then the code looking for IPMI fwinfo can scan devices on a
bus and look for ones that implement the IPMI class.
This will let the ACPI scope be defined by the calling
code so the IPMI code doesn't have to know the scope.

Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the
Error typedef. Since then, we've moved to include qemu/osdep.h
everywhere. Its file comment explains: "To avoid getting into
possible circular include dependencies, this file should not include
any other QEMU headers, with the exceptions of config-host.h,
compiler.h, os-posix.h and os-win32.h, all of which are doing a
similar job to this file and are under similar constraints."
qapi/error.h doesn't do a similar job, and it doesn't adhere to
similar constraints: it includes qapi-types.h. That's in excess of
100KiB of crap most .c files don't actually need.
Add the typedef to qemu/typedefs.h, and include that instead of
qapi/error.h. Include qapi/error.h in .c files that need it and don't
get it now. Include qapi-types.h in qom/object.h for uint16List.
Update scripts/clean-includes accordingly. Update it further to match
reality: replace config.h by config-target.h, add sysemu/os-posix.h,
sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h
comment quoted above similarly.
This reduces the number of objects depending on qapi/error.h from "all
of them" to less than a third. Unfortunately, the number depending on
qapi-types.h shrinks only a little. More work is needed for that one.

Replace the int32 softfloat-specific typedef with int32_t.
This change was made with
find hw include fpu target-* -name '*.[ch]' | xargs sed -i -e 's/\bint32\b/int32_t/g'
together with manual removal of the typedef definition, and
manual undoing of some mis-hits where macro arguments were
being used for token pasting rather than as a type.
The uses in hw/ipmi/ should not have been using this type at all.
