From: Abhishek Kumar <abhishekkumar8222@xxxxxxxxx>
In a preparatory step, let's return timestamp_t values from
commit_graph_generation(), use timestamp_t for local variables and
define GENERATION_NUMBER_INFINITY as (2 ^ 63 - 1) instead.
We rename GENERATION_NUMBER_MAX to GENERATION_NUMBER_V1_MAX to
represent the largest topological level we can store in the commit data
chunk.
With corrected commit dates implemented, we will have two such *_MAX
variables to denote the largest offset and largest topological level
that can be stored.
