When running OpenWrt inside an LXC container no shell is opend as LXC
defaults to a virtual /dev/console.
This patch allows to enter a shell after starting the container via
`lxc-start`, without it is only posible to access a shell on tty1 via
`lxc-console`.

CONFIG_BINFMT_MISC allows it to add support for new executable formats
to the kernel from user space, the kernel will then detect for example a
java binary and call the java execution program automatically. I am not
aware that this feature is used in OpenWrt and this could be used to
exploit something. Deactivate it for all targets for now.

It was previously added in 546fced, which was part of "intel-microcode:
load as early as possible" series.
Unfortunately the conditionals added to GRUB config caused error on boot,
because on sysupgrade, bootloader is not updated and is left with old
features/modules. Since this module is needed for early microcode load
and transition to this needs to be done step by step, enable the test
module now, so that every newly created image has it already embedded.

This adds initial support for kernel 4.19 to the x86 target.
The patches and the kernel configurations were copied from kernel 4.14
and then refreshed.
The legacy and the genode target will not support PAE any more because
they use a CPU type which does not support PAE, the generic sub target
still supports PAE.

This refreshes the kernel configuration for kernel 4.14.
First this was run for the legacy target:
make kernel_oldconfig
Then for all targets including the legacy target this was run:
make kernel_oldconfig CONFIG_TARGET=subtarget
The option CONFIG_104_QUAD_8 was added to the generic configuration
because it would have been automatically removed.

This makes it possible to use different sub target configurations for

any more.
