Dr. David Alan Gilbert 44b1ff319c migration: pre_save return int
Modify the pre_save method on VMStateDescription to return an int
rather than void so that it potentially can fail.

Changed zillions of devices to make them return 0; the only
case I've made it return non-0 is hw/intc/s390_flic_kvm.c that already
had an error_report/return case.

Note: If you add an error exit in your pre_save you must emit
an error_report to say why.

Alistair Francis 3dc6f86936 Convert error_report() to warn_report()
Convert all uses of error_report("warning:"... to use warn_report()
instead. This helps standardise on a single method of printing warnings
to the user.

All of the warnings were changed using these two commands:
    find ./* -type f -exec sed -i \
      's|error_report(".*warning[,:] |warn_report("|Ig' {} +

Indentation fixed up manually afterwards.

The test-qdev-global-props test case was manually updated to ensure that
this patch passes make check (as the test cases are case sensitive).

Markus Armbruster da34e65cb4 include/qemu/osdep.h: Don't include qapi/error.h
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.

bad idea to use a QOM typename macro to initialize it, because in
general we're free to rename QOM types as part of code refactoring
and cleanup.  For the handful of devices that were doing this by
mistake, replace the QOM typenames with the corresponding literal
strings.

Since 39bffca203 (qdev: register all
types natively through QEMU Object Model), TypeInfo as used in
the common, non-iterative pattern is no longer amended with information

Fix the documented QOM examples:

 sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h

Since frequently the wrong examples are being copied by contributors of
new devices, fix all types in the tree:

 sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c
 sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c

This also avoids to piggy-back these changes onto real functional

Hans de Goede 9a77a0f589 usb: split packet result into actual_length + status
Since with the ehci and xhci controllers a single packet can be larger
then maxpacketsize, it is possible for the result of a single packet
to be both having transferred some data as well as the transfer to have
an error.

An example would be an input transfer from a bulk endpoint successfully
receiving 1 or more maxpacketsize packets from the device, followed
by a packet signalling halt.

While already touching all the devices and controllers handle_packet /
handle_data / handle_control code, also change the return type of
these functions to void, solely storing the status in the packet. To
make the code paths for regular versus async packet handling more
uniform.

This patch unfortunately is somewhat invasive, since makeing the qemu
usb core deal with this requires changes everywhere. This patch only
prepares the usb core for this, all the hcd / device changes are done
in such a way that there are no functional changes.

This patch has been tested with uhci and ehci hcds, together with usb-audio,
usb-hid and usb-storage devices, as well as with usb-redir redirection
with a wide variety of real devices.

Note that there is usually no need to directly set packet->actual_length
form devices handle_data callback, as that is done by usb_packet_copy()

In qdev, each bus in practice identified an abstract superclass, but
this was mostly hidden.  In QOM, instead, these abstract classes are
explicit so we can move bus properties there.

All bus property walks are removed, and all device property walks
are changed to look along the class hierarchy instead.

We would have duplicates if class A defines some properties and its
subclass B does not define any, because class_b->props will be
left equal to class_a->props.

The solution here is to reintroduce the class_base_init TypeInfo
callback, that was present in one of the early QOM versions but
removed (on my request...) before committing.

This breaks global bus properties, an obscure feature when used
with the command-line which is actually useful and used when used by
backwards-compatible machine types.  So this patch also adjusts the
global bus properties in hw/pc_piix.c to refer to the abstract class.

Globals and other properties must be modified in the same patch to
avoid complications related to initialization ordering.

Gerd Hoffmann 9d55d1adc8 usb: add serial number generator
This patch adds a function which creates unique serial numbers for usb
devices and puts it into use.  Windows guests tend to become unhappy if
they find two identical usb devices in the system.  Effects range from
non-functional devices (with yellow exclamation mark in device manager)
to BSODs.  Handing out unique serial numbers to devices fixes this.

With this patch applied almost all emulated devices get a generated,
unique serial number.  There are two exceptions:

 * usb-storage devices will prefer a user-specified serial number
   and will only get a generated number in case the serial property
   is unset.
 * usb-hid devices keep the fixed serial number "42" as it is used
   to signal "remote wakeup actually works".
   See commit 7b074a22da

Gerd Hoffmann f1ae32a1ec usb: the big rename
Reorganize usb source files.  Create a new hw/usb/ directory and move
all usb source code to that place.  Also make filenames a bit more
descriptive.  Host adapters are prefixed with "hch-" now, usb device
emulations are prefixed with "dev-".  Fixup paths Makefile and include
paths to make it compile.  No code changes.
