Add the capability to display summary statistics to pg_xlogdump.
The new --stats/--stats=record options to pg_xlogdump display per
rmgr/per record statistics about the parsed WAL. This is useful to
understand what the WAL primarily consists of, to allow targeted
optimizations on application, configuration, and core code level.
It is likely that we will want to fine tune the statistics further,
but the feature already is quite helpful.
