support for ext4/EMMC in target_files and OTA generation
Move the image sizes into a more generic key-value file. Make them
optional. Add additional key/value pairs describing what kind of
filesystem the device uses. Pass new fs-type-related arguments in
edify scripts when mounting and reformatting partitions.
Don't include all the init.*.rc files from the regular system in
recovery -- they aren't needed, and break recovery on some devices.
