Refactor some code related to backend statistics
This commit changes the way pending backend statistics are tracked by
moving them into a new structure called PgStat_BackendPending, removing
PgStat_BackendPendingIO. PgStat_BackendPending currently only includes
PgStat_PendingIO for the pending I/O stats.
pgstat_flush_backend() is extended with a "flags" argument to control
which parts of the stats of a backend should be flushed.
With this refactoring, it becomes easier to plug into backend statistics
more data. A patch to add information related to WAL in this stats kind
is under discussion.
