Overflow errors are range errors

* etc/NEWS: Mention this.
* doc/lispref/errors.texi (Standard Errors):
Document overflow-error, which was formerly undocumented.
It is a range error, not a domain error.
* src/data.c (syms_of_data): overflow-error and (undocumented)
underflow-error are subtypes range-error, not domain-error.
This fixes bugs in timezone-time-from-absolute and in
erc-ctcp-reply-PING.
