pgsql: pgstat: rename some pgstat_send_* functions to pgstat_report_*.

pgstat: rename some pgstat_send_* functions to pgstat_report_*.

Only the pgstat_send_* functions that are called from outside pgstat*.c are
renamed (the rest will go away). This is done separately from the - quite
large - shared memory statistics patch to make review easier.
