Backport fsync queue compaction logic to all supported branches. This backports commit 7f242d880b5b5d9642675517466d31373961cf98, except for the counter in pg_stat_bgwriter. The underlying problem (namely, that a full fsync request queue causes terrible checkpoint behavior) continues to be reported in the wild, and this code seems to be safe and robust enough to risk back-porting the fix.
