Fix progress estimate by fixing checkpoint data

The number of transactions since the last checkpoint block was set to
over 100K, but there were no checkpoint blocks other than genesis,
and the timestamp of last checkpoint block was incorrect as well. These
led to the progress indicator always being very close to zero.

This adds checkpoint blocks rougly every 10K blocks and corrects the
other metadata.
