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 *:*

husb: Make control transactions asynchronous (Max Krasnyansky)

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.

uhci: Change default transaction lifetime to 32 frames (Max Krasnyansky)

Transaction lifetime was originally set to 10 frames. That was an arbitrary
number I picked without much thinking :).
I'm changing that to 32 frames because things like interrupt transfers
and such are scheduled at that rate. It seems like 1/32 is accepted as
lowest supported rate. OHCI, for example, defines exactly 32 interrupt
heads.

While testing USB webcam under XP I noticed that interrupt transactions were
being canceled and then resubmitted on a regular basis, which works but is a
waste of CPU cycles. This change fixes that.

Fix up pxe boot (Glauber Costa)

As discussed in
http://lists.gnu.org/archive/html/qemu-devel/2008-08/msg00667.html,
current pxe boot is broken for some use cases. The problem
goes away if we reduce the number of allowed bits in the address space
to 32 (which has the side effect of reducing guest max mem size to 4Gb).

After digging for a while, it turns out that it happens because pxelinux
tries to access address 0x10009e9a6, which does not fit a 32-bit address.
A closer look, however, reveals this access is totally valid: It's just
0x9e9a6 with an add carry.

To avoid this, this patch casts the address passed to the POPL macro to
a 32-bit value. This is also done, although just theorectically, for
PUSHL too.
