b870472db5 usb: add audio device model
This brings a usb audio device to qemu.  Output only, fixed at
16bit stereo @ 480000 Hz.  Based on a patch from
H. Peter Anvin <hpa@linux.intel.com>

Usage: add '-device usb-audio' to your qemu command line.

Works sorta ok on a idle machine.  Known issues:

 * Is *very* sensitive to latencies.
 * Burns quite some CPU due to usb polling.

In short:  It brings the qemu usb emulation to its limits.  Enjoy!

e0b8e72dd9 usb: fix port reset
commit 891fb2cd45 removed the implicit
detach before (re-)attaching in usb_attach().  Some usb host controllers
used that behavior though to do a port reset by a detach+attach
sequence.

This patch establishes old behavior by adding a new usb_reset() function
for port resets and putting it into use, thereby also unifying port
reset behavior of all host controllers.  The patch also adds asserts to
usb_attach() and usb_detach() to make sure the calls are symmetrical.

891fb2cd45 usb: claim port at device initialization time.
This patch makes qemu assign a port when creating the device, not when
attaching it.  For most usb devices this isn't a noticable difference
because they are in attached state all the time.

The change affects usb-host devices which live in detached state while
the real device is unplugged from the host.  They have a fixed port
assigned all the time now instead of getting grabbing one on attach and
releasing it at detach, i.e. they stop floating around at the usb bus.

The change also allows to simplify usb-hub.  It doesn't need the
handle_attach() callback any more to configure the downstream ports.
This can be done at device initialitation time now.  The changed
initialization order (first grab upstream port, then register downstream
ports) also fixes some icky corner cases.  For example it is not possible
any more to plug the hub into one of its own downstream ports.

The usb host adapters must care too.  USBPort->dev being non-NULL
doesn't imply any more the device is in attached state.  The host
adapters must additionally check the USBPort->dev->attached flag.

Zap data pointer from USBPacket, add a QEMUIOVector instead.
Add a bunch of helper functions to manage USBPacket data.
Switch over users to the new interface.

Note that USBPacket->len was used for two purposes:  First to

transfered bytes or the status code on async transfers.  There
is a new result variable for the latter.  A new status code
was added to catch uninitialized result.

Nobody creates iovecs with more than one element (yet).
Some users are (temporarely) limited to iovecs with a single
element to keep the patch size as small as possible.

4706ab6cc0 usb: Replace device_destroy bus op with a child_detach port op
Note this fixes 2 things in one go, first of all the device_destroy bus
op should be a device_detach bus op, as pending async packets from the
device should be cancelled on detach not on destroy.

Secondly having this as a bus op won't work with companion controllers, since
then there will be 1 bus driven by the ehci controller and thus 1 set of bus
ops, but the device being detached may be downstream of a handed over port.
Making the detach of a downstream device a port op allows the ehci controller
to forward this to the companion controller port for handed over ports.

Note that currently all usb1 emulated device claim to be fullspeed, this

hardware keyboards, mice and tablets usually are lo-speed, so reporting these

c1ecb40a61 usb core: add migration support
Yes, seriously.  There is no migration support at all for usb devices.
They loose state, especially the device address, and stop responding
because of that.  Oops.

Luckily there is so much broken usb hardware out there that the guest
usually just kicks the device hard (via port reset and
reinitialization), then continues without a hitch.  So we got away with
that in a surprising high number of cases.

The arrival of remote wakeup (which enables autosuspend support) changes
that picture though.  The usb devices also forget that it they are
supposed to wakeup, so they don't do that.  The host also doesn't notice
the device stopped working in case it suspended the device and thus
expects it waking up instead of polling it.  Result is that your mouse
is dead.

Lets start fixing that.  Add a vmstate struct for USBDevice.

5f69076b8d usb: add port property.
This allows to explictily set the physical port where you want to
plug the usb device.  Example:

  -device usb-tablet,bus=usb.0,port=2

With explicit port addressing qemu can and will not automagically add
USB Hubs.  This means that:

  (a) You can plug two devices of your choice into the two uhci
      root ports.
  (b) If you want plug in more that two devices you have to care
      about adding a hub yourself.

Plugging a hub works this way:

  -device usb-hub,bus=usb.0,port=1

Use this to add a device to the hub:

  -device usb-tablet,bus=usb.0,port=1.1

a980a065fb usb: move USB_REQ_{GET,SET}_CONFIGURATION handling to common code
This patch adds fields to the USBDevice struct for the current
speed (hard-wired to full speed for now) and current device
configuration.  Also a init function is added which inializes
these fields.  This allows USB_REQ_{GET,SET}_CONFIGURATION

For most drivers the conversion is trivial ad they support a single
configuration only anyway.  One exception is bluetooth where some
device-specific setup code runs after get/set configuration.  The
other is usb-net which actually has two configurations so the
the code to check for the active configuration has been adapted.

72cf2d4f0e Fix sys-queue.h conflict for good
Problem: Our file sys-queue.h is a copy of the BSD file, but there are
some additions and it's not entirely compatible. Because of that, there have
been conflicts with system headers on BSD systems. Some hacks have been
introduced in the commits 15cc923584,
f40d753718,
96555a96d7 and
3990d09adf but the fixes were fragile.

Solution: Avoid the conflict entirely by renaming the functions and the
file. Revert the previous hacks.

a5d2f7273c qdev/usb: make qemu aware of usb busses.
Move usb code from vl.c to usb-bus.c and make it use the new data
structures added by qdev conversion.  qemu usb core should be able
to handle multiple USB busses just fine now (untested though).

Kill some usb_*_init() legacy functions, use usb_create_simple()
instead.

Kill some FIXMEs added by the first qdev/usb patch.

376253ece4 monitor: Rework API (Jan Kiszka)
Refactor the monitor API and prepare it for decoupled terminals:
term_print functions are renamed to monitor_* and all monitor services
gain a new parameter (mon) that will once refer to the monitor instance
the output is supposed to appear on. However, the argument remains
unused for now. All monitor command callbacks are also extended by a mon
parameter so that command handlers are able to pass an appropriate
reference to monitor output services.

For the case that monitor outputs so far happen without clearly
identifiable context, the global variable cur_mon is introduced that
shall once provide a pointer either to the current active monitor (while
processing commands) or to the default one. On the mid or long term,
those use case will be obsoleted so that this variable can be removed
again.

Due to the broad usage of the monitor interface, this patch mostly deals
with converting users of the monitor API. A few of them are already
extended to pass 'mon' from the command handler further down to internal
functions that invoke monitor_printf.

At this chance, monitor-related prototypes are moved from console.h to
a new monitor.h. The same is done for the readline API.

bb5fc20f7c monitor: Rework modal password input (Jan Kiszka)
Currently, waiting for the user to type in some password blocks the
whole VM because monitor_readline starts its own I/O loop. And this loop
also screws up reading passwords from virtual console.

Patch below fixes the shortcomings by using normal I/O processing also
for waiting on a password. To keep to modal property for the monitor
terminal, the command handler is temporarily replaced by a password
handler and a callback infrastructure is established to process the
result before switching back to command mode.

c0f4ce7751 monitor: Rework early disk password inquiry (Jan Kiszka)
Reading the passwords for encrypted hard disks during early startup is
broken (I guess for quiet a while now):
 - No monitor terminal is ready for input at this point
 - Forcing all mux'ed terminals into monitor mode can confuse other
   users of that channels

To overcome these issues and to lay the ground for a clean decoupling of
monitor terminals, this patch changes the initial password inquiry as
follows:
 - Prevent autostart if there is some encrypted disk
 - Once the user tries to resume the VM, prompt for all missing
   passwords
 - Only resume if all passwords were accepted

5d0c5750bb usb: Support for removing device by host addr, improved auto filter syntax (Max Krasnyansky)
This patch adds support for removing USB devices by host address.
Which is usefull for things like libvirtd because there is no easy way to
find guest USB address of the host device.
In other words you can now do:
   usb_add host:3.5
   ...
   usb_del host:3.5
Before the patch 'usb_del' did not support 'host:' notation.

----
Syntax for specifying auto connect filters has been improved.
Old syntax was
    host:bus.dev
    host:pid:vid
New syntax is
    host:auto:bus.dev[:pid:vid]
In both the cases any attribute can be set to "*".

New syntax is more flexible and lets you do things like
    host:3.*:5533:* /* grab any device on bus 3 with vendor id 5533 */

It's now possible to remove auto filters. For example:
    usb_del host:auto:3.*:5533:*

Active filters are printed after all host devices in 'info usb' output.
Which now looks like this:

  Device 1.1, speed 480 Mb/s
    Hub: USB device 1d6b:0002, EHCI Host Controller
  Device 1.4, speed 480 Mb/s
    Class 00: USB device 1058:0704, External HDD
  Auto filters:
    Device 3.* ID *:*

4b096fc9ec husb: support for USB host device auto connect (Max Krasnyansky)
QEMU can now automatically grab host USB devices that match the filter.
For now I just extended 'host:X.Y' and 'host:VID:PID' syntax to handle
wildcards. So for example if you do something like
   usb_add host:5.*
QEMU will automatically grab any non-hub device with host address 5.*.

Same with the 'host:PID:*', we grab any device that matches PID.

Filtering itself is very generic so we can probably add more elaborate
syntax like 'host:BUS.ADDR:VID:PID'. So that we can do 'host:5.*:6000:*'.

Anyway, it's implemented using a periodic timer that scans host devices
and grabs those that match the filter. Timer is started when the first
filter is added.

We now keep the list of all host devices that we grabbed to make sure that
we do not grab the same device twice.

btw It's currently possible to grab the same host device more than once.
ie You can just do "usb_add host:1.1" more than once, which of course does
not work. So this patch fixes that issue too.

Along with auto disconnect patch that I send a minute ago the setup is very
seamless now. You can just allocate some usb ports to the VMs and plug/unplug
devices at any time.

1f3870ab24 husb: support for USB host device auto disconnect (Max Krasnyansky)
I got really annoyed by the fact that you have to manually do
usb_del in the monitor when host device is unplugged and decided
to fix it :)

Basically we now automatically remove guest USB device
when the actual host device is disconnected.

At first I've extended set_fd_handlerX() stuff to support checking
for exceptions on fds. But unfortunately usbfs code does not wake up
user-space process when device is removed, which means we need a
timer to periodically check if device is still there. So I removed
fd exception stuff and implemented it with the timer.
