When installing a package, we should have /tmp and /cache mounted and
nothing else. Ensure this is true by explicitly mounting them and
unmounting everything else as the first step of every install.
Also fix an error in the progress bar that crops up when you do
multiple package installs in one instance of recovery.

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).
(Cherrypicked from gingerbread w/slight edits.)

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.
