Remove the wacky notion of "roots" and "root paths" (those things that
look like "FOO:some/path" instead of just "/foo/some/path"). Let each
device specify its own table of available partitions and how to mount
them (needed for devices that use both MTD/yaffs2 and EMMC/ext4
partitions).

Recovery itself no longer needs to access all these partitions;
manipulation of them is done by the updater binary. This is a small
first step towards removing roots entirely.
