depends: create a hostid and buildid and add option for salts
These add very simple sanity checks to ensure that the build/host toolchains have not changed since the last run. If they have, all ids will change and packages will be rebuilt. For more complicated usage (like parsing dpkg), HOST_ID_SALT/BUILD_ID_SALT may be used to introduce arbitrary data to the ids.
