Remove some useless uses of ARCH_CFLAGS -- this variable was never set
so will always be empty. The uses were accidental: in commit 0c439cbf8
Juan Quintela removed ARCH_CFLAGS in favour of CFLAGS (which in turn
became QEMU_CFLAGS). However in commit be17dc90 a use of it was
reintroduced (apparently accidentally) by Michael S. Tsirkin, and then
I subsequently cut-n-pasted that into a number of other configure

Some locale settings let make fail or create wrong results
because tr '[:lower:]' '[:upper:]' which is used to convert
from lower to upper case depends on the locale.
With locale tr_TR.UTF-8, lower case 'i' is not converted to 'I'.
This results in wrong entries in config-host.h like these ones:
#define CONFIG_QEMU_PREFiX "/usr/local"
#define CONFIG_QEMU_BiNDiR "/usr/local/bin"
This problem was reported by Emre Ersin.
The same problem occurs when configure creates the target specific
files config-target.mak. They get wrong declarations:
TARGET_CRiS=y
TARGET_i386=y
TARGET_MiCROBLAZE=y
TARGET_MiPS64=y
TARGET_MiPS=y
TARGET_UNiCORE32=y
It is sufficient to restrict the conversion to the characters a-z.
Using this explicit range avoids the dependency on the locale
settings and is also shorter.
v2:
POSIX says that 'tr a-z' is unspecified outside of the POSIX
locale, so we must set LC_ALL=C to make sure that we are using
POSIX (hint from Eric Blake, thanks).

The macro offsetof is defined in stddef.h. It is conforming to
the standards C89, C99 and POSIX.1-2001 (see man page), so it
is a sufficiently old standard.
Therefore chances are very high that QEMU never needs a local
definition of this macro.
osdep.h already includes stddef.h, so this patch simply removes
the unneeded code from the files configure and osdep.h.
If we ever need the local definition again, it should be added
to compiler.h (the macro is usually provided with the compiler,
it is not OS specific).

This patch adds the posibility to filter out certain devices from redirecion.
To use this pass the filter property to -device usb-redir. The filter
property takes a string consisting of filter rules, the format for a rule is:
<class>:<vendor>:<product>:<version>:<allow>
-1 can be used to allow any value for a field.
Muliple rules can be concatonated using | as a separator. Note that if
a device matches none of the passed in rules, redirecting it will not be
allowed!
Example:
-device usb-redir,filter='-1:0x0781:0x5567👎0|0x08👎-1👎1'
This example will deny the Sandisk Cruzer Blade being redirected, as it
has a usb id of 0781:5567, it will allow any other usb mass storage devices,
and it will deny any other devices (the default for devices not matching any
of the rules.

The most common use of -net tap is to connect a tap device to a bridge. This
requires the use of a script and running qemu as root in order to allocate a
tap device to pass to the script.
This model is great for portability and flexibility but it's incredibly
difficult to eliminate the need to run qemu as root. The only really viable
mechanism is to use tunctl to create a tap device, attach it to a bridge as
root, and then hand that tap device to qemu. The problem with this mechanism
is that it requires administrator intervention whenever a user wants to create
a guest.
By essentially writing a helper that implements the most common qemu-ifup
script that can be safely given cap_net_admin, we can dramatically simplify
things for non-privileged users. We still support existing -net tap options
as a mechanism for advanced users and backwards compatibility.
Currently, this is very Linux centric but there's really no reason why it
couldn't be extended for other Unixes.
A typical invocation would be similar to one of the following:
qemu linux.img -net bridge -net nic,model=virtio
qemu linux.img -net tap,helper="/usr/local/libexec/qemu-bridge-helper"
-net nic,model=virtio
qemu linux.img -netdev bridge,id=hn0
-device virtio-net-pci,netdev=hn0,id=nic1
qemu linux.img -netdev tap,helper="/usr/local/libexec/qemu-bridge-helper",id=hn0
-device virtio-net-pci,netdev=hn0,id=nic1
The default bridge that we attach to is br0. The thinking is that a distro
could preconfigure such an interface to allow out-of-the-box bridged networking.
Alternatively, if a user wants to use a different bridge, a typical invocation
would be simliar to one of the following:
qemu linux.img -net bridge,br=qemubr0 -net nic,model=virtio
qemu linux.img -net tap,helper="/usr/local/libexec/qemu-bridge-helper --br=qemubr0"
-net nic,model=virtio
qemu linux.img -netdev bridge,br=qemubr0,id=hn0
-device virtio-net-pci,netdev=hn0,id=nic1
qemu linux.img -netdev tap,helper="/usr/local/libexec/qemu-bridge-helper --br=qemubr0",id=hn0
-device virtio-net-pci,netdev=hn0,id=nic1

The ideal way to use qemu-bridge-helper is to give it an fscap of using:
setcap cap_net_admin=ep qemu-bridge-helper
Unfortunately, most distros still do not have a mechanism to package files
with fscaps applied. This means they'll have to SUID the qemu-bridge-helper
binary.
To improve security, use libcap to reduce our capability set to just
cap_net_admin, then reduce privileges down to the calling user. This is
hopefully close to equivalent to fscap support from a security perspective.

This patch adds a helper that can be used to create a tap device attached to
a bridge device. Since this helper is minimal in what it does, it can be
given CAP_NET_ADMIN which allows qemu to avoid running as root while still
satisfying the majority of what users tend to want to do with tap devices.
The way this all works is that qemu launches this helper passing a bridge
name and the name of an inherited file descriptor. The descriptor is one
end of a socketpair() of domain sockets. This domain socket is used to
transmit a file descriptor of the opened tap device from the helper to qemu.
The helper can then exit and let qemu use the tap device.
