Large C files

FYI, here are all the C files with over 6k lines:

- 45133 ./interfaces/ecpg/preproc/preproc.c
- 33651 ./backend/parser/gram.c
- 17551 ./backend/parser/scan.c
14209 ./bin/pg_dump/pg_dump.c
10590 ./backend/access/transam/xlog.c
9764 ./backend/commands/tablecmds.c
8681 ./backend/utils/misc/guc.c
- 7667 ./bin/psql/psqlscan.c
7213 ./backend/utils/adt/ruleutils.c
6814 ./backend/utils/adt/selfuncs.c
6176 ./backend/utils/adt/numeric.c
6030 ./pl/plpgsql/src/pl_exec.c

I have dash-marked the files that are computer-generated. It seems
pg_dump.c and xlog.c should be split into smaller C files.
