OpenBLT shared params (#4417)
* OpenBLT: linker file: use last 16 bytes of ram for shared area

This area is used for communication between FW and OpenBLT.

* OpenBLT: startup: invalidate only DFU breadcumb from startup code

Same location (but different seed) is used for shared param's
signature in OpenBLT.

* OpenBLT: enable shared params

* OpenBLT: enable hooks

If 0x01 is stored in shared param idx=0, then stay in OpenBLT forever.

* Jump to OpenBLT: store proper shared param when OpenBLT is requested

TODO: calculate and store CRC too!

* OpenBLT: move shared_params to start of RAM

* Bootloader: Allocate 16 bytes at start of RAM for bootloader shared area

* OpenBLT: shared_params: reuse same .c and .h file for main application

* OpenBLT: shared_params: enable CRC check

* OpenBLT: no need to manualy set breadcumb before reset

* Revert "OpenBLT: startup: invalidate only DFU breadcumb from startup code"

This reverts commit 6b064714b953560227ae53e38355332cf9f46f7f.

* OpenBLT: guard for builds without OpenBLT

* OpenBLT: reboot to OpenBLT on CAN request with ID=0x667 and DLC=2

* config: options to enable OpenBLT on CAN interfaces

* OpenBLT: comments

Openblt (#3430)
* Makefile: define BOOTLOADER=1 for linker in case of OpenBLT too

This will reserve first 32K of flash for bootloader.

* OpenBLT: include into build

* board: subaru eg33: add OpenBLT board code

* board: subaru eg33: use OpenBLT

* Board: Subaru EG33: OpenBLT: reuse HAL and CMSIS from OpenBLT submodule

* Board: Subaru EG33: OpenBLT: reuse linker file from OpenBLT too

* OpenBLT for MRE

* OpenBLT: MRE: adjust LD memory map for smallest variat of MCU on MRE

* OpenBLT: enable for MRE

* OpenBLT: disable CRC check of user application

This allows us to use DFU tool to flash main application too.

* hex2dfu: fresh binary for linux

* OpenBLT: extract common part of OpenBLT makefiles to openblt.mk

* OpenBLT: enable CRC check of user application for MRE and EG33

CRC (actually just a summ) of few first vectors is stored at 0x1c
offset. This is reserved vector for Cortex-M3, M4 and M7

* common_make: append OpenBLT CRC to dfu files

This should allow to use DFU to do main application update when
when OpenBLT is used as bootloader. hex2dfu will store same
styled CRC as OpenBLT expects to see in user app.

* OpenBLT reorganization

Move common stuff to hw_layer/ports/

* OpenBLT: proteus

* Proteus: enable OpenBLT for F4 and F7

Compilation tested only
