f349474920 minikconfig: implement allnoconfig and defconfig modes
Apart from defconfig (which is a no-op),
allyesconfig/allnoconfig/randcondfig can be implemented simply by ignoring
the RHS of assignments and "default" statements.  The RHS is replaced
respectively by "true", "false" or a random value.

However, allyesconfig and randconfig do not quite work, because all the
files for hw/ARCH/Kconfig are sourced and therefore you could end up
enabling some ARM boards in x86 or things like that.  This is left for
future work, but I am leaving it in to help debugging minikconf itself.

allnoconfig mode is tied to a new configure option, --without-default-devices.

e0e312f352 build: switch to Kconfig
The make_device_config.sh script is replaced by minikconf, which
is modified to support the same command line as its predecessor.

The roots of the parsing are default-configs/*.mak, Kconfig.host and
hw/Kconfig.  One difference with make_device_config.sh is that all symbols
have to be defined in a Kconfig file, including those coming from the
configure script.  This is the reason for the Kconfig.host file introduced
in the previous patch. Whenever a file in default-configs/*.mak used
$(...) to refer to a config-host.mak symbol, this is replaced by a
Kconfig dependency; this part must be done already in this patch
for bisectability.

5f71eac06e Makefile, configure: Support building rST documentation
Add support to our configure and makefile machinery for building
our rST docs into HTML files.

Building the documentation now requires that sphinx-build is
available; this seems better than allowing half the docs to
be built if it is not present but having half of them missing.
(In particular it means that assuming that distros configured with
--enable-docs they'll get a helpful error from configure telling
them the new build dependency.)

b76806d4ec authz: delete existing ACL implementation
The 'qemu_acl' type was a previous non-QOM based attempt to provide an
authorization facility in QEMU. Because it is non-QOM based it cannot be
created via the command line and requires special monitor commands to
manipulate it.

The new QAuthZ subclasses provide a superset of the functionality in
qemu_acl, so the latter can now be deleted. The HMP 'acl_*' monitor
commands are converted to use the new QAuthZSimple data type instead
in order to provide temporary backwards compatibility.

8953caf3cd authz: add QAuthZPAM object type for authorizing using PAM
Add an authorization backend that talks to PAM to check whether the user
identity is allowed. This only uses the PAM account validation facility,
which is essentially just a check to see if the provided username is permitted
access. It doesn't use the authentication or session parts of PAM, since
that's dealt with by the relevant part of QEMU (eg VNC server).

Consider starting QEMU with a VNC server and telling it to use TLS with
x509 client certificates and configuring it to use an PAM to validate
the x509 distinguished name. In this example we're telling it to use PAM
for the QAuthZ impl with a service name of "qemu-vnc"

 $ qemu-system-x86_64 \
     -object tls-creds-x509,id=tls0,dir=/home/berrange/security/qemutls,\
             endpoint=server,verify-peer=yes \
     -object authz-pam,id=authz0,service=qemu-vnc \
     -vnc :1,tls-creds=tls0,tls-authz=authz0

This requires an /etc/pam/qemu-vnc file to be created with the auth
rules. A very simple file based whitelist can be setup using

  $ cat > /etc/pam/qemu-vnc <<EOF
  account         requisite       pam_listfile.so item=user sense=allow file=/etc/qemu/vnc.allow
  EOF

The /etc/qemu/vnc.allow file simply contains one username per line. Any
username not in the file is denied. The usernames in this example are
the x509 distinguished name from the client's x509 cert.

  $ cat > /etc/qemu/vnc.allow <<EOF
  CN=laptop.berrange.com,O=Berrange Home,L=London,ST=London,C=GB
  EOF

More interesting would be to configure PAM to use an LDAP backend, so
that the QEMU authorization check data can be centralized instead of
requiring each compute host to have file maintained.

The main limitation with this PAM module is that the rules apply to all
QEMU instances on the host. Setting up different rules per VM, would
require creating a separate PAM service name & config file for every
guest. An alternative approach for the future might be to not pass in
the plain username to PAM, but instead combine the VM name or UUID with
the username. This requires further consideration though.

This is a simple move of Python code that wraps common QEMU

By treating that code as a real Python module, we can more easily:
 * reuse code
 * have a proper place for the module's own unittests
 * apply a more consistent style
 * generate documentation

56f41de737 vhost-net-user: add stubs for when no virtio-net device is present
hw/net/vhost_net.c needs functions that are declared in net/vhost-user.c: the
vhost-user code is always compiled into QEMU, only the constructor
net_init_vhost_user is unreachable.  Also, net/vhost-user.c needs functions
declared in hw/virtio/vhost-stub.c even if no virtio device exists.

Break this dependency.  First, add a minimal version of net/vhost-user.c,
with no functionality and no dependency on vhost code.  Second, #ifdef out
the calls back to net/vhost-user.c from hw/net/vhost_net.c.

While at it, this patch fixes the CONFIG_VHOST_NET_USE*D* typo.

96566d09aa configure: improve usbfs check
The current check to test if usbfs support should be compiled or not
solely relies on the presence of <linux/usbdevice_fs.h>, without
actually checking that all definition used by Qemu are provided by
this header file.

With sufficiently old kernel headers, <linux/usbdevice_fs.h> may be
present, but some of the definitions needed by Qemu may not be
available.

This commit improves the check by building a small program that
actually tests whether the necessary definitions are available.

In addition, it fixes a bug where have_usbfs was set to "yes"
regardless of the result of the test.

e633a5c661 configure: Avoid non-portable 'test -o/-a'
POSIX says that it is better to use &&/|| and two separate test
invocations than it is to try and use -a and -o (in fact, there
are some tests that are inherently ambiguous to parse if the
user passes in corner-case input like "(").

Since we cannot guarantee which shell runs configure, we cannot
rely on -o/-a always following bash's parser rules.

The machine description we send is being (silently) thrown on the floor
by GDB and GDB silently uses the default machine description, because
the xml parse fails on <feature> nested within <feature>.
Changes to the xml in qemu source code have no effect.

In addition, the default machine description has fs_base, which fails to
be retrieved, which breaks the whole register window.  Add it and the

d99e97e691 configure: Add a proper check for openpty() in libutil
On Linux (and maybe some BSDs), we require libutil for the openpty()
function. However, this library is not available on some other systems, so
we currently use a fragile if-statement in the configure script to check
whether we need the library or not. Unfortunately, we also hard-coded a
"-lutil" in the tests/Makefile.include file, so this breaks the build on
Solaris, for example (see buglink below). To fix the issue, add the "-lutil"
to "libs_tools" in the configure script instead, then this gets properly
propagated to the tests, too.
And while we're at it, also replace the fragile if-statement in the confi-
gure script with a proper link-check for the availability of this function.

SDL1.2 was deprecated in the 2.12.0 release with:

  commit e52c6ba341
  Author: Daniel P. Berrange <berrange@redhat.com>
  Date:   Mon Jan 15 14:25:33 2018 +0000

    ui: deprecate use of SDL 1.2 in favour of 2.0 series

    The SDL 2.0 release was made in Aug, 2013:

      https://www.libsdl.org/release/

    That will soon be 4 + 1/2 years ago, which is enough time to consider
    the 2.0 series widely supported.

    Thus we deprecate the SDL 1.2 support, which will allow us to delete it
    in the last release of 2018. By this time, SDL 2.0 will be more than 5
    years old.

99e1a93bbf configure: LM32 Milkymist Texture Mapping Unit (tmu2) also depends of X11
Commit 5f9b1e3506 remove the dependency between OpenGL and X11.
However the milkymist-tmu2 device do require X11.
When using SDL, the configure script sets need_x11=yes, so the X11
flags are populated to the makefiles.
When building without SDL, X11 is not pulled and populated, leading
to a link failure:

    LINK    lm32-softmmu/qemu-system-lm32

Enforce the X11 dependency when the LM32 target is built.
This will allow us to build QEMU without SDL.

d339d766d1 qemu-io: Add generic function for reinitializing optind.
On FreeBSD 11.2:

  $ nbdkit memory size=1M --run './qemu-io -f raw -c "aio_write 0 512" $nbd'
  Parsing error: non-numeric argument, or extraneous/unrecognized suffix -- aio_write

After main option parsing, we reinitialize optind so we can parse each
command.  However reinitializing optind to 0 does not work on FreeBSD.
What happens when you do this is optind remains 0 after the option
parsing loop, and the result is we try to parse argv[optind] ==
argv[0] == "aio_write" as if it was the first parameter.

The FreeBSD manual page says:

  In order to use getopt() to evaluate multiple sets of arguments, or to
  evaluate a single set of arguments multiple times, the variable optreset
  must be set to 1 before the second and each additional set of calls to
  getopt(), and the variable optind must be reinitialized.

(From the rest of the man page it is clear that optind must be
reinitialized to 1).

The glibc man page says:

  A program that scans multiple argument vectors,  or  rescans  the  same
  vector  more than once, and wants to make use of GNU extensions such as
  '+' and '-' at  the  start  of  optstring,  or  changes  the  value  of
  POSIXLY_CORRECT  between scans, must reinitialize getopt() by resetting
  optind to 0, rather than the traditional value of 1.  (Resetting  to  0
  forces  the  invocation  of  an  internal  initialization  routine that
  rechecks POSIXLY_CORRECT and checks for GNU extensions in optstring.)

This commit introduces an OS-portability function called
qemu_reset_optind which provides a way of resetting optind that works
on FreeBSD and platforms that use optreset, while keeping it the same
as now on other platforms.

Note that the qemu codebase sets optind in many other places, but in
those other places it's setting a local variable and not using getopt.
This change is only needed in places where we are using getopt and the
associated global variable optind.

7be41675f7 configure: Force the C standard to gnu99
Different versions of GCC and Clang use different versions of the C standard.
This repeatedly caused problems already, e.g. with duplicated typedefs:

 https://lists.gnu.org/archive/html/qemu-devel/2018-11/msg05829.html

or with for-loop variable initializers:

 https://lists.gnu.org/archive/html/qemu-devel/2019-01/msg00237.html

To avoid these problems, we should enforce the C language version to the
same level for all compilers. Since our minimum compiler versions is
GCC v4.8, our best option is "gnu99" for C code right now ("gnu17" is not
available there yet, and "gnu11" is marked as "experimental"), and "gnu++98"
for the few C++ code that we have in the repository.

a442fe2f2b sdl: add support for high resolution window icon
Modern desktop environments can render icons at very large sizes,
especially with high DPI screens. Providing a 32x32 pixel bitmap is
nowhere near sufficient anymore.

When displayed in GNOME shell the QEMU icon looks awful, having been
scaled up to at least x4 its base size. This is compounded by the fact
that the BMP file doesn't do transparency, so while we've removed white
pixels, we still have anti-aliased nearly-white pixels which make the
logo look appalling on black backgrounds.

Loading a high resolution PNG icon addresses both problems, but requires
use of the extra SDL2_image library.

The icon associated with a GtkWindow is just a hint to window managers
and not all of them will honour it. Some will instead want to show the
icon listed by the .desktop file. The desktop file is located based on
the application ID, which is set using g_set_prgname. QEMU has not
historically provided a desktop file or set its app ID, so it got a
broken icon in GNOME shell, which is now fixed.

The accepted standards for desktop applications declare that application
logos / icons should be installed under $prefix/share/icons, so use this
directory location.

Pre-rendered icons are provided at the standard sizes expected for GUI
applications, along with the scalable SVG, to ensure maximum portability.

The PNGs are rendered from the SVG using inkscape, however, this is not
wired up into the default make rules to avoid requiring inkscape as a
mandatory tool in build systems / developer workstations.

2e33c3f848 configure: Only build the s390-ccw bios if the compiler supports -march=z900
We want to build our s390-ccw bios with -march=z900 so that it also
works with the oldest s390x CPU that we support with TCG. However,
Clang on s390x does not support -march=z900 anymore, so we can not
use this compiler to build the s390-ccw bios. Thus add a proper test
to the configure script to see whether the compiler is usable.

755ee70ff7 configure: keep track of Python version
Some functionality is dependent on the Python version
detected/configured on configure.  While it's possible to run the
Python version later and check for the version, doing it once is
preferable.  Also, it's a relevant information to keep in build logs,
as the overall behavior of the build can be affected by it.
