  MYNEWT-329
  MYNEWT-354
  STM32f407 discovery board BSP
  mbedtls; use smaller version of SHA256.
  boot; boot loader does not need to call os_init() anymore, as bsp_init() has been exported.
  boot; app does not need the dependency to mbedtls
  slinky; time-based waits must use OS_TICKS_PER_SEC.
  bootutil; adjust unit tests to work with status upkeep outside sys/config.
  bootutil; was returning wrong image header in response when swithing images. Add boot_set_req() routine for unit test use.
  boot/bootutil; remove debug console use from bootloader.
  bootutil/imgmgr; output of boot now shows the fallback image.
  imgmgr; automatically confirm image as good for now.
  bootutil; add 'confirm' step, telling that image was confirmed as good. Otherwise next restart we'll go back to old image.
  bootutil; make status element size depend on flash alignment restrictions.
  boot, imgmgr; return the slot number for test image.
  bootutil; move routines reading boot-copy-status from loader.c to bootutil_misc.c.
  boot; return full flash location of status bytes, instead of just offset.
  boot; don't use NFFS or FCB for keeping status. Interim commit.
