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.

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.

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.

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

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 *:*

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.

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.
