* src/mes.c (assoc_string, car, cdr, list, null_p, eq_p, values, acons,
length__, length, error, append2, append_reverse, reverse_x_, assq,
assoc): Move to ...
* src/core.c: New file.
* build-aux/configure-lib.sh (mes_SOURCES): Add it.
* simple.make (MES_SOURCES): Likewise.
* build-aux/snarf.sh: Likewise.
