Fixes the following security issues:
CVE-2016-0749: The smartcard interaction in SPICE allows remote attackers to
cause a denial of service (QEMU-KVM process crash) or possibly execute
arbitrary code via vectors related to connecting to a guest VM, which
triggers a heap-based buffer overflow.
CVE-2016-2150: SPICE allows local guest OS users to read from or write to
arbitrary host memory locations via crafted primary surface parameters, a
similar issue to CVE-2015-5261.
The pyparsing check has been dropped from configure, and the spice protocol
definition is again included, so the workarounds can be removed.

Client/gui support is gone upstream (moved to spice-gtk / virt-viewer), so
add Config.in.legacy handling for them.
Lz4 is a new optional dependency, so handle it.
The spice protocol definition is no longer included and instead used from
spice-protocol. The build system uses pkg-config --variable=codegendir to
find the build time path of this, which doesn't take our STAGING_DIR prefix
into consideration, so it needs some help. The installed protocol
definition will likewise be newer than the generated files, so we need to
workaround that to ensure they are not regenerated (which needs host python
/ pyparsing).

Celt051 is no longer a hard dependency, and opus is a new optional

Python / pyparsing are not needed as the tarball contains the generated

these are used at build time), but we need a small workaround to convince
configure that they really aren't needed.
Alsa-lib is only needed for client support, and the configure script checks

This patch backports two patches that have been sent upstream as a pull
request in order to fix sshd for MIPS64 n32.
The first patch adds support for detecting the MIPS ABI during the
configure phase.
The second patch sets the right value to seccomp_audit_arch taking into
account the MIPS64 ABI.
Currently seccomp_audit_arch is set to AUDIT_ARCH_MIPS64 or
AUDIT_ARCH_MIPSEL64 (depending on the endinness) when openssh is built
for MIPS64. However, that's only valid for n64 ABI. The right macros for
n32 ABI defined in seccomp.h are AUDIT_ARCH_MIPS64N32 and
AUDIT_ARCH_MIPSEL64N32, for big and little endian respectively.
Because of that an sshd built for MIPS64 n32 rejects connection attempts
and the output of strace reveals that the problem is related to seccomp
audit:

In buildroot ffmpeg uses x264 as optional dependency if
BR2_PACKAGE_FFMPEG_GPL is enabled at the same time.
If BR2_PACKAGE_FFMPEG_GPL is disabled and ffmpeg is built without x264
support before x264 itself is build, x264 picks up certain ffmpeg libs
as optional dependency leading to build errors because x264 does not
correctly link statically against ffmpeg.
To avoid a circular dependency and to avoid teaching x264 how to
correctly link statically with ffmpeg we just disable all ffmpeg-
related options.

systemd's configure is looking in $PATH to find utilities that will be
needed at runtime.
Usually, those utilties, when installed on the host, will be found in
the same path they would be present on the target. For example,
/usr/bin/mount on the host would also be /usr/bin/mount on the target,
and all is find.
Except when we need to install a host variant of util-linux, which will
install mount in $(HOST_DIR), in which case systemd's configure would
find that one.
Of course, it is also very well possible that those utilities are not
installed on the host in the same location they would be on the target,
in case a user has manually installed some of those (e.g. in /usr/local/
or in /opt/)
Forcibly set the path to those utilities, as they are expected to be on
the target.
For kexec, we can set it even though we do not depend on it (yet).
systemd will appropriately test it at runtime.
For quota, we point to non-existing files, so as to catch errors at
runtime. It is to be noted that quotacheck is optional, while quotaon
does not seem to be (a service file is always installed, that uses it).
Note: utilties listed in the order they appear in configure.ac

When building with old gcc versions (such as gcc 4.3), the current
version of kmod fails with:
shared/util.c:52: error: expected identifier or '(' before 'do'
shared/util.c:52: error: expected identifier or '(' before 'while'
This is due to a use of the internal assert_cc() macro outside of a
function, while this macro is defined for old gcc versions in a way that
cannot be used outside functions.
This wasn't noticed by the autobuilders because we don't have such old
target compilers. On the host side, we have some autobuilder instances
with such old gcc versions, but host-kmod is only used by the linux
package, which is never tested by the autobuilders.

CVE-2017-1000367 - Potential overwrite of arbitrary files on Linux
On Linux systems, sudo parses the /proc/[pid]/stat file to determine the
device number of the process's tty (field 7). The fields in the file are
space-delimited, but it is possible for the command name (field 2) to
include spaces, which sudo does not account for. A user with sudo
privileges can cause sudo to use a device number of the user's choosing by
creating a symbolic link from the sudo binary to a name that contains a
space, followed by a number.
If SELinux is enabled on the system and sudo was built with SELinux support,
a user with sudo privileges may be able to to overwrite an arbitrary file.
This can be escalated to full root access by rewriting a trusted file such
as /etc/shadow or even /etc/sudoers.
