Support resuming block based OTAs

Browse source

Add support for transfer list version 3, which allows us to
verify the status of each command and resume an interrupted
block based OTA update. Notes on the changes:

 - Move the previous BlockImageUpdateFn to a shorter and
   reusable PerformBlockImageUpdate, which can be used also
   in BlockImageVerifyFn for verification.

 - Split individual transfer list commands into separate
   functions with unified parameters for clarity, and use
   a hash table to locate them during execution.

 - Move common block reading and writing to ReadBlocks and
   WriteBlocks to reduce code duplication, and rename the
   readblock and writeblock to less confusing read_all and
   write_all.

The coding style of the new functions follows the existing
style in the updater/edify code.
