- make mod_info_html_cmd_string() thread safe

- fix minor buffer overrun in mod_info_html_cmd_string() (it would only
hammer a \0 up to 5 bytes past the end of the buffer... nothing big)

- mod_info_load_config() switched to use getword_conf() just like the real
config parsing routines

- replace a bunch of ap_snprintf()/rputs() pairs with rprintf() for more
efficiency
