support incremental updates of boot image

Modify applypatch to be able to write MTD partitions as well as read
them.  Make applypatch save a backup copy of the contents of an MTD
partition it reads in cache, to be used in case an update is
interrupted while writing back to MTD.  Modify OTA package creation
script to send boot image updates in patch form.
