This reverts most of commit 3d1237fb2a.
The commit claims to sort the output of "-device help" "by
functionality rather than alphabetical". Issues:
* The output was unsorted before, not alphabetically sorted.
Misleading, but harmless enough.
* The commit doesn't just sort the output of "-device help" as it
claims, it adds categories to each line of "-device help", and it
prints devices once per category. In particular, devices without a
category aren't shown anymore. Maybe such devices should not exist,
but they do. Regression.
* Categories are also added to the output of "info qdm". Silent
change, not nice. Output remains unsorted, unlike "-device help".
I'm going to reimplement the feature we actually want, without the
warts. Reverting the flawed commit first should make it easier to
review. However, I can't revert it completely, since DeviceClass
member categories has been put to use. So leave that part in.

In the original code, qmp_get_command_list is used to construct
a list of all commands' name. To get the information of all qga
commands, it traverses the name list and search the command info
with its name. So it can cause O(n^2) in the number of commands.
This patch adds an interface to traverse the qmp command list by
QmpCommand to replace qmp_get_command_list. It can decrease the

If a socket is closed it remains in TIME_WAIT state for some time. On operating
systems using BSD sockets the endpoint of the socket may not be reused while in
this state unless SO_REUSEADDR was set on the socket. On windows on the other
hand the default behaviour is to allow reuse (i.e. identical to SO_REUSEADDR on
other operating systems) and setting SO_REUSEADDR on a socket allows it to be
bound to a endpoint even if the endpoint is already used by another socket
independently of the other sockets state. This can even result in undefined
behaviour.
Many sockets used by QEMU should not block the use of their endpoint after being
closed while they are still in TIME_WAIT state. Currently QEMU sets SO_REUSEADDR
for such sockets, which can lead to problems on Windows. This patch introduces
the function socket_set_fast_reuse that should be used instead of setting
SO_REUSEADDR when fast socket reuse is desired and behaves correctly on all
operating systems.
As a failure of this function can only be caused by bad QEMU internal errors, an
assertion handles these situations. The return value is still passed on, to
minimize changes in client code and prevent unused variable warnings if NDEBUG
is defined.

There's no Intel CPU with family=6,model=2, and Linux and Windows guests
disable SEP when seeing that combination due to Pentium Pro erratum #82.
In addition to just having SEP ignored by guests, Skype (and maybe other
applications) runs sysenter directly without passing through ntdll on
Windows, and crashes because Windows ignored the SEP CPUID bit.
So, having model > 2 is a better default on qemu64 and qemu32 for two
reasons: making SEP really available for guests, and avoiding crashing
applications that work on bare metal.
model=3 would fix the problem, but it causes CPU enumeration problems
for Windows guests[1]. So let's set model=6, that matches "Athlon
(PM core)" on AMD and "P2 with on-die L2 cache" on Intel and it allows
Windows to use all CPUs as well as fixing sysenter.

Currently, -smbios type=T,NAME=VAL,... adds one field (T,NAME) with
value VAL to fw_cfg for each unique NAME. If NAME occurs multiple
times, the last one's VAL is used (before the QemuOpts conversion, the
first one was used).
Multiple -smbios can add multiple fields with the same (T, NAME).
SeaBIOS reads all of them from fw_cfg, but uses only the first field
(T, NAME). The others are ignored.
"First one wins, subsequent ones get ignored silently" isn't nice. We
commonly let the last option win. Useful, because it lets you
-readconfig first, then selectively override with command line
options.
Clean up -smbios to work the common way. Accumulate the settings,
with later ones overwriting earlier ones. Put the result into fw_cfg
(no more useless duplicates).
Bonus cleanup: qemu_uuid_parse() no longer sets SMBIOS system uuid by
side effect.

Currently Xen hvm s3 has a bug coming from the difference between
qemu-traditioanl and qemu-xen. For qemu-traditional, the way to
resume from hvm s3 is via 'xl trigger' command. However, for
qemu-xen, the way to resume from hvm s3 inherited from standard
qemu, i.e. via QMP, and it doesn't work under Xen.
The root cause is, for qemu-xen, 'xl trigger' command didn't reset
devices, while QMP didn't unpause hvm domain though they did qemu
system reset.
We have two qemu patches and one xl patch to fix Xen hvm s3 bug.
This patch is the qemu patch 1. It adjusts qemu wakeup so that
Xen s3 resume logic (which will be implemented at qemu patch 2)
will be notified after qemu system reset.

These use a 32-bit load-of-immediate to save a mflr+addi+mtlr sequence.
Tested with a Windows 98 guest (pretty much the most recent thing I
could run on my PPC machine) and kvm-unit-tests's sieve.flat. The
speed up for sieve.flat is as high as 10% for qemu-system-i386, 25%
(no kidding) for qemu-system-x86_64 on my PowerBook G4.

Some drivers will have driver specifics options but no filename.
This new bool allow the block layer to treat them correctly.
The .bdrv_needs_filename is set in drivers not having .bdrv_parse_filename and
not having .bdrv_open.
The first exception to this rule will be the quorum driver.

The following sequence happens:
- the SeaBIOS virtio-blk driver does not support the WCE feature, which
causes QEMU to disable writeback caching
- the Linux virtio-blk driver resets the device, finds WCE is available
but writeback caching is disabled; tells block layer to not send cache
flush commands
- the Linux virtio-blk driver sets the DRIVER_OK bit, which causes
writeback caching to be re-enabled, but the Linux virtio-blk driver does
not know of this side effect and cache flushes remain disabled
The bug is at the third step. If the guest does know about CONFIG_WCE,
QEMU should ignore the WCE feature's state. The guest will control the
cache mode solely using configuration space. This change makes Linux
do flushes correctly, but Linux will keep SeaBIOS's writethrough mode.
Hence, whenever the guest is reset, the cache mode of the disk should
be reset to whatever was specified in the "-drive" option. With this
change, the Linux virtio-blk driver finds that writeback caching is
enabled, and tells the block layer to send cache flush commands
appropriately.
