configure: Avoid duplicate flags when calling compile_prog
This patch removes redundant shell code and cleans it a little bit.
Shell macro compile_prog takes two arguments:
local_cflags and local ldflags.
$QEMU_CFLAGS is added automatically to the cflags, so there is no need
to pass it as an argument.
It is also unnecessary to pass -Werror twice.
$flag is a compiler warning option, so it should be in local_cflags
instead of local_ldflags.

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.

bdrv_media_changed() lets you poll for media change, but it returns
"don't know" except with block driver "host_floppy".
FDrive member media_changed gets set on device initialization and by
fdctrl_change_cb(), and cleared by fdctrl_media_changed(). Thus, it's
set on first entry to fdctrl_media_changed() since device
initialization or virtual media change.
fdctrl_media_changed() ignores media_changed unless
bdrv_media_changed() returns "don't know". If we change media via
monitor (setting media_changed), and the new media's block driver
returns 0, we lose. Fortunately, "host_floppy" always returns 1 on
first call. Brittle. Clean it up not to rely on it.

block/raw: Fix to forward method bdrv_media_changed()
Block driver "raw" forwards most methods to the underlying block
driver. However, it doesn't implement method bdrv_media_changed().
Makes bdrv_media_changed() always return -ENOTSUP.
I believe -fda /dev/fd0 gives you raw over host_floppy, and disk
change detection (fdc register 7 bit 7) is broken. Testing my theory
requires a computer museum, though.

async: Allow nested qemu_bh_poll calls
qemu may segfault when a BH handler first deletes a BH and then (possibly
indirectly) calls a nested qemu_bh_poll(). This is because the inner instance
frees the BH and deletes it from the list that the outer one processes.
This patch deletes BHs only in the outermost qemu_bh_poll instance.
Commit
7887f620 already tried to achieve the same, but it assumed that the BH
handler would only delete its own BH. With a nested qemu_bh_poll(), this isn't
guaranteed, so that commit wasn't enough. Hope this one fixes it for real.
