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.

(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 *:*

USB is 99.8% async now :). 0.2% is the three control requests that
we need to execute synchronously. We could off-load that to a thread
or something but it's not worth the pain since those requests are
performed only during device initialization (ie when device is
connected to the VM).
The change is a bit bigger than I wanted due to the fact that generic
handle_packet()/handle_control() interface was not designed for
async transactions. So I ended up adding custom handle_packet()
code to usb-linux. We can make that generic if/when some other
component needs it.

This is a follow up to the async UHCI patch. Both BULK and ISOC transactions
are now fully asynchrounous. I left CONTROL synchronous for now, ideally
we want it to be async too and it should not be that hard to do now.
This patch obviously requires UHCI patch. The combo has been tested with
various devices. See the UHCI patch description for list of the devices.
Most of the testing was done with the KVM flavor of QEMU.

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.
