rHG21ef5f75edf0: revlog: use "entry_point" phrasing for loading the revlog
Summary

The main entry for the revlog will not necessary be the index, but a small
"docket". So we change the variable names and we move the initialisation of the
index_file and data_file after that first entry point have been read.
