Fix const usage in iri.c

Browse Source 
* src/iri.c (remote_to_utf8): Do not qualify with const the output pointer.
(do_conversion): Use the provided input parameter as const.
(idn_encode): casts to remote_to_utf8 parameters are no longer needed.
* src/iri.h: Adjusted remote_to_utf8 prototype.
* src/url.c: It is no longer necessary to cast new_url to const char.
