22d0703853 config-host.mak: rename confdir to qemu_confdir
$confdir is a confusing name, as it's not clear if it's "the system
config dir" or "the Qemus-specific directory inside the config dir".
$qemu_confdir makes it more clear.

The current C code that uses CONFIG_QEMU_CONFDIR should be safe, as now
create_config generates the same #define name (CONFIG_QEMU_CONFDIR) for
both "confdir" and "qemu_confdir" variables.

6aae2a2e0e config-host.mak: rename datadir to qemu_datadir
Autoconf concept of "datadir" is supposed to be "$prefix/share", not
"$prefix/share/PACKAGE", so using datadir for the Qemu-specific
directory is confusing.

The current C code that uses CONFIG_QEMU_DATADIR should be safe, as now
create_config generates the same #define name (CONFIG_QEMU_DATADIR) for
both "datadir" and "qemu_datadir" variables.

10ea68b343 configure: rename $confdir to $qemu_confdir
There's no "confdir" variable on Autoconf, but it's good to make it
clear that it's a variable for the Qemu-specific subdirectory inside
$sysconfdir.

850da188a2 configure: rename $docdir to $qemu_docdir
The autoconf "docdir" variable is used for the program-specific

c00b280805 configure: rename $datadir to $qemu_datadir
The variable is used for the qemu-specific directory and has a different
meaning of the autoconf "datadir" variable (that's used for the
$prefix/share directory, not for $prefix/share/PACKAGE).

This doesn't change behavior or interfaces, it's just an internal
variable rename.

650ab98d1d tracetool: Rewrite infrastructure as python modules
The tracetool script is written in shell and has hit several portability
problems due to shell quirks or external tools across host platforms.
Additionally the amount of string processing and lack of real data
structures makes it tough to implement code generator backends for
tracers that are more complex.

This patch replaces the shell version of tracetool with a Python
version.  The new tracetool design is:

  scripts/tracetool.py - top-level script
  scripts/tracetool/backend/ - tracer backends live here (simple, ust)
  scripts/tracetool/format/  - output formats live here (.c, .h)

There is common code for trace-events definition parsing so that
backends can focus on generating code rather than parsing input.

Support for all existing backends (nop, stderr, simple, ust,
and dtrace) is added back in follow-up patches.

8fb0315165 configure: Remove useless uses of ARCH_CFLAGS
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
feature tests.

bb55b712e8 Fix conversion from lower to upper case with Turkish locale
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).

82246040ea osdep: Remove local definition of macro offsetof
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).

6af165892c usb-redir: Add the posibility to filter out certain devices from redirecion
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.

a7c36ee492 Add support for net bridge
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

47e98658f5 Add cap reduction support to enable use as SUID
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.

7b93fadf3a Add basic version of bridge helper
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.

359bc95d3e configure: Fix test for supported host CPU type
The test for whether the host CPU is supported had several problems:
 * the attempt to fall back to TCI was done as a duplicate
   test, very late (so "--cpu foo" would fail early but "--cpu unicore32"
   would fail late, differently, and after configure had already
   printed a lot of output)
 * a number of CPUs only supported as guests were included in the
   list of CPUs we would accept as valid hosts, which would result
   in a late compile failure on those systems rather than a
   configure failure or fallback to TCI
 * bailing out for an unsupported CPU happened before the main
   option parsing, so "configure --help" wouldn't work

Fix these by folding the setting of ARCH into the first test for
supported host CPU, removing spurious guest-only CPU names from it,
and moving the "fall back to TCI" code earlier.

QEMU applications on W32 don't use the default SDL compiler flags:

Instead of a GUI application, a console application is created.

This has disadvantages (there is always an empty console window) and
no obvious reason, so this patch removes the strange flag modification.

Tests using the glib test framework are independent from libcheck and
afaik are always present (although having a configure switch to disable
them is probably worth it).

21d4a791da configure: tighten pie toolchain support test for tls variables
Some toolchains don't support pie properly when tls variables are
in use.  Disallow pie when such toolchains are detected.

3439eec34f configure: check for EFD_NONBLOCK | EFD_CLOEXEC flags
Add check for the EFD_NONBLOCK and EFD_CLOEXEC flags to the
CONFIG_EVENTFD test.
This fixes the following build failure on Fedora 9:

      CC    event_notifier.o
    event_notifier.c: In function `event_notifier_init':
    event_notifier.c:21: error: `EFD_NONBLOCK' undeclared (first use in this function)
    event_notifier.c:21: error: (Each undeclared identifier is reported only once
    event_notifier.c:21: error: for each function it appears in.)
    event_notifier.c:21: error: `EFD_CLOEXEC' undeclared (first use in this function)
    make: *** [event_notifier.o] Error 1

40d6444e91 configure: build position independent executables on x86-Linux hosts
Change the default on x86 Linux hosts to building PIE (position
independent executables); instead of restricting the option to
user-only targets, apply it to all targets.

In addition, set the relocation sections to read-only (relro) when
available; this reduces the attack surface by disallowing changes to
relocation tables at runtime.

While PIE reduces performance and relro increases load time, it
greatly improves security, with the potential to reduce a code
execution vulnerability to a self denial of service.

Non-x86 are not changed, as they require TCG changes; neither are
non-Linux, due to lack of test coverage.

f2338fb48a configure: Do not use 'sed -i'
'sed -i' is not defined in POSIX. It doesn't work on Mac OS X the way
it's used in configure (without suffix argument). This patch implements
Peter Maydell's idea of xattr.h detection.
