add osmo_quote_str_buf3, osmo_escape_str_buf3

There already are osmo_quote_str_buf() and osmo_quote_str_buf2(), same
for _escape_, but none of them return the snprintf() like string length.
A private function does, publish this in the API.

The returned chars_needed is required to accurately allocate sufficient
size in string functions that call osmo_quote_str/osmo_escape_str. I am
adding such in osmo-upf.git.
