Michael Paquier c776550e46 Change stat_lock.wait_time to double precision
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.
