On some cases, such as under KVM, tb_invalidate_phys_page_range()
may be called for large addresses, when qemu is configured to more than
4GB of RAM.

On these cases, qemu was crashing because it was using an index too
large for l1_map[], that supports only 32-bit addresses when compiling
without CONFIG_USER_ONLY.

Right now, we sprinkle #if defined(QEMU_IMG) && defined(QEMU_NBD) all over the
code.  It's ugly and causes us to have to build multiple object files for
linking against qemu and the tools.

This patch introduces a new file, qemu-tool.c which contains enough for
qemu-img, qemu-nbd, and QEMU to all share the same objects.

This also required getting qemu-nbd to be a bit more Windows friendly.  I also
changed the Windows block-raw to use normal IO instead of overlapping IO since
we don't actually do AIO yet on Windows.  I changed the various #if 0's to
 #if WIN32_AIO to make it easier for someone to eventually fix AIO on Windows.

After this patch, there are no longer any #ifdef's related to qemu-img and
qemu-nbd.

according to the alpha arch reference, the literal field of an operate
instruction is unsigned:

If bit <12> of the instruction is 1, an 8-bit zero-extended literal
constant is formed by bits
<20:13> of the instruction. The l teral is interpreted as a positive
integer bet ween 0 and 255
and is zero-extended to 64 bits.

This patch fixes the mis-interpretation of the literal field.

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.

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.
All other devices I have are not affected.

OpenBSD doesn't use AIO so don't try to build compatfd when not using AIO.

Also make sure to call qemu_aio_init() from bdrv_init.  Everything that uses
bdrv calls bdrv_init so it makes sense to init aio from there instead of
in every single tool.
