libgnutls: Fixed "no_renegotiation" alert handling at incorrect timing.
The server sending a "no_renegotiation" alert in an unexpected timing,
followed by an invalid second handshake was able to cause a TLS 1.3
client to crash via a null-pointer dereference. The crash happens in the
application's error handling path, where the gnutls_deinit function is
called after detecting a handshake failure (#1071).

The ControlValue structure is currently defined with a 16-bit hole
(causing unaligned access to the numElements_ field, though that's a
separate topic).
This structure has a static assertion to ensure that its size does not
change without due care, as it forms part of our ABI and is used in
Serialisation between the pipeline handlers and IPA components.
The m68k architecture is the only target which fails this assertion,
which is likely because it can pack the structure more efficiently,
producing a different binary size.
This is likely an area we will tackle before stabilising our ABI, but
until then, disable m68k builds as libcamera is not expected to be
supported on this target.

Extract from bug report:
"In usb_modeswitch Makefile dispatcher-script, dispatcher-dynlink and
dispatcher-statlink are .PHONY targets. The result is that sources are
compiled also when install targets are called.
USB_MODESWITCH_INSTALL_TARGET_CMDS calls $(MAKE) which is a call to
parallel make eg. make -j9. So the install phase can install empty
usb_modeswitch binary (happened once) if the compiler have just cleared
the binary and install command installs it before compiler writes the
binary. USB_MODESWITCH_INSTALL_TARGET_CMDS should call $(MAKE1)."
Instead of disabling parellel install, use install-common target instead
of install-{dyn,stat}link targets. Indeed, the dynamic or static
usb_modeswitch_dispatcher binary will be built by
all-with-{dyn,stat}link-dispatcher targets, there is no need to rebuild
it during the install step

Currently, the libselinux package sets the CONFIG_DEFAULT_SECURITY_SELINUX
kernel option. However, as of kernels >= 5.1, this option is superseded in
favor of the CONFIG_LSM option, a comma-separated list of LSMs the kernel
should initialize in order.
As the previous behavior of this package sets the kernel's default and only
LSM to initialize to SELinux, it is safe to set this string to just selinux.
If the user wants additional LSM's, they may do so with a custom kernel config.

Allow users to provide custom SELinux modules to be part of the final
policy. A new configuration variable is added, pointing to list of
directories containing the custom modules.
SELinux modules do require a metadata.xml file to be well integrated
in the refpolicy build. If this file isn't provided, it will be
automatically created.
For now, this option requires the extra modules to be directly into
the BR2_REFPOLICY_EXTRA_MODULES directory, and subfolders aren't
supported. They may never be, as having subfolders could introduce
issues when two different modules have the same name (which isn't
supported by the refpolicy).

The refpolicy is configured to use a monolithic build, compiling all the
available modules (whether they're 'base' or 'modules' ones) in the
binary policy. The result is a quite big SELinux policy, with a lot more
rules than what would be needed in a Buildroot image.
Refactor the refpolicy build configuration to enable less modules by
default. To achieve this, all the modules marked as being part of the
'base' policy are kept but all the modules marked as being only
'modules' are disabled. Then a static list of modules (in addition to
the already selected 'base' ones) are enabled. The result is a much
smaller refpolicy: tests showed a reduction of the binary policy from
2.4M to 249K (~90% smaller).
This minimal set of SELinux modules should allow to boot a system in
enforcing mode in the future. It currently does not work, not because
extra modules are needed, but because of required changes within the
selected modules.
This patch would break backward compatibility as the refpolicy will no
longer have all the modules provided by the project, but only those
selected. This should not be an issue as this configuration was not
suitable directly for a real system. Modifications had to be done. If we
still find out later that this is an issue for someone, we'll have the
ability to mimic what was done previously thanks to other mechanisms
(such as providing the upstream policy as a "custom" policy location).

Set the SELinux file security contexts using setfiles when generating
root filesystem images.
Without such security contexts created at build time, they need to be
setup at first boot by running the restorecon utility on the target.
This has two drawbacks:
- You have to special case the first boot, which cannot be done in
enforcing mode, and will have to run restorecon, then reboot.
- You cannot support read-only filesystems.
By setting up the security contexts at build time, we can have a
filesystem image that is immediately ready to boot an SELinux system
in enforcing mode, including if the root filesystem is read-only.

This version is based on the OpenBSD Mg, but with more features, one of
which being the no-ncurses/termcap support, which heavily reduces the
