Other statistics views (pg_stat_io, pg_stat_database, etc.) use float8 for all measured-time columns, the new pg_stat_lock standing out as an outlier by using bigint. This commit aligns pg_stat_lock with the other stats views for consistency. Like pg_stat_io, the time is stored in microseconds, and is displayed in milliseconds with a conversion done when the view is queried. While on it, replace a use of "long" by PgStat_Counter, the former could overflow for large wait times where sizeof(long) is 4 bytes (aka WIN32). Bump catalog version.
