applypatch changes for patching recovery image
Make some changes needed to applypatch in order to store the recovery
image in the system partition as a binary patch relative to the boot
image:
- make applypatch use shared libraries, so it's smaller. It will
need to be on the main system so it can install the recovery
image. Make an applypatch_static binary for use in recovery
packages (still needed for updating cupcake devices to donut).
- output the results of patching to an in-memory buffer and write
that to the partition; there's no convenient /tmp for us to us.
(This should be basically a no-op in recovery, since /tmp is a
ramdisk anyway.)
