4857a70189 stm32: Improve out-of-bounds check on erase sector index calculation 
Avoid wrapping the sector index, as that could potentially result in
erasing the booloader itself.

Also, move the stm32f4_sector_index() inline into erase_page().

8316d2f0af armcm_boot: Introduce application_check_valid() 
Move application_check_valid() in bootentry.c to armcm_boot.c and make
the check specific to the ARM cortex-m.  On these ARM machines it is
easier to validate the application stack address.

Also rename jump_to_application() to application_jump().

Also rename flash_read_block() to application_read_flash() and move to
armcm_boot.c .
