This causes the flash loader startup code to fall into the loader when
the application sets the boot address to zero.

altos: Validate boot chain start address2013-05-08T03:16:52+00:00Keith Packardkeithp@keithp.com2013-03-23T09:18:55+00:00urn:sha1:35ef1f17e3efaa6d586ab7bb301f8133d52023b6
If the first block of boot memory has been smashed, and the start
address is bogus, don't bother trying to jump to the
application. This makes the system more resiliant to flash failures,
presuming the loader erases the first block, programs the other blocks
and then finally comes back to program the first block.

Split out code into separate files.
Add support for getting back to boot loader from application.
