Remove some unused utility functions.

* purple_escape_js was used for WebKit stuff, now gone.
* purple_ipv6_address_is_valid was removed earlier and the prototype was
accidentally left in.
* purple_markup_extract_info_field was used for MSN and Yahoo, now gone.
* purple_str_binary_to_ascii seems to be from MSN and/or Yahoo.
* purple_uts35_to_str was used for MSN, now gone.
