In order to mitigate against Spectre V4, add an option that will, at
boot time, verify if the CPU supports the SPEC_CTRL MSR; if so, it'll
attempt to disable the feature.

Mitigation) of the "Speculative Execution Side Channel Mitigations"
document, version 2, published by Intel: https://goo.gl/nocTcj

- Show the value of each symbol in the jump-to dialog.
- Search names and prompts separately in the jump-to dialog.
Previously, '_BAR$' wouldn't match FOO_BAR if it had a prompt,
because '_BAR$' was matched against the string 'FOO_BAR "prompt"'.
- Show the working directory in save/load dialog boxes. Paths will be
relative to it, and Carles Cufi pointed out that it might not be
obvious.
Also allow ~ to be used to refer to the home directory.
- Implement scroll offset for edit boxes. This makes it clearer when
they're scrolled horizontally.
Piggyback an update of Kconfiglib to the latest version (no functional
changes).

Setting of CONFIG_HEAP_MEM_POOL_SIZE was done in the board defconfig
because open-amp was doing recursive builds and setting it the
defconfig made sure all builds were consistent. However, now that we
don't do recursive builds this will get properly picked by from the
sample specific conf file.

The STM32L4x2 SoCs need to control the isolation of the USB features
from VDDUSB. This is done through the PWR_CR2 bit USV, however the
current code checks for the PWR_CR2_PVME1 bit instead, which is only
available on Cat. 3 devices. This bug is also present int the HAL and
likely copied from there.
Replace the check by PWR_CR2_USV instead.

The STM32L4x2 SoCs need to control the isolation of the USB features

in stm32l4xx_ll_pwr.h wrongly checks for the PWR_CR2_PVME1 bit, which

The STM32L432 SoC has a standard non-OTG USB controller. Add an entry
for it in stm32l432.dtsi and add the corresponding DTS fixup entries.
The controller is kept disabled and should be enabled at the board
level.

USB OTG is currently enable for the whole STM32L4 family, while only a
few of them actually support it:
- STM32L475, STM32L476 and STM32L496 have an OTG controller
- STM32L432, STM32L433 and STM32L452 have an USB controller
- STM32L431, STM32L451 and STM32L471 do not have any USB controller
Fix that by moving the DT entry from stm32l4.dtsi to stm32l475.dtsi
and by adding a #ifdef #endif around the corresponding DTS fixup
entries.

With recent changes to open-amp we can now include and build it directly

Some code was developped around MPU support in ealy stage
of feature introduction. This code was gated under MPU_ENABLE
flag which does not exist and hence code has never been
enabled nor tested.
Since there has been futher MPU development since then, it seems
safer to simply remove that code and associated Kconfig symbols
to avoid that someone starts using it while it was not part of
MPU development track.

Zephyr code routinely assumes conventional ILP32/LP64 integer
behavior, and occasionally relies on it to perform some nice tricks.
This is despite the fact that this behavior (while pervasively adopted
and in use on all architectures we care about supporting) isn't
actually guaranteed by the language standard which allows much looser
semantics than actual exist on hardware.
Put it into the intmath section of this test as a build time thing.
