Martino Facchin 4c901d3f9f [AVR] Discover newer bootloader at runtime 
Replaces #4280, only checks for the bootloader once

Tested with Hoodloader2, should work with every LUFA-derived bootloader released after 2014 (.apitable_signatures section must be placed at end of the flash)

BootloaderAPITable.S :

.global BootloaderAPI_Signatures
BootloaderAPI_Signatures:

    .long BOOT_START_ADDR ; Start address of the bootloader
    .word 0xDF00 ; Signature for the CDC class bootloader
    .word 0xDCFB ; Signature for a LUFA class bootloader

makefile:

BOOT_API_LD_FLAGS    += $(call BOOT_SECTION_LD_FLAG, .apitable_signatures,  BootloaderAPI_Signatures,  8)
