Rework delta struct and modify code accordingly

Start to move the delta struct away from an assumed package name scheme and
towards something that is package (or even filename) agnostic. This will
allow us much greater flexibility in the usage of deltas (maybe even sync
DBs some day) as well as allowing code outside of delta.h/delta.c to be much
cleaner with less of a need for snprintf() calls.
