http_uri:decode equivalent in uri_string module

[Loïc Hoguin]

After using uri_string:normalize(URI, [return_map]) or equivalent, there 
are very few %HexHex left to decode. For example, the path will only 
have %2f left and it should be trivial to do the final decode after 
you've split the path into a path segment. It's a similar situation for 
the other fragments. The function string:replace/4 is probably enough 
for these cases.

In a related PR https://github.com/erlang/otp/pull/2492 we have 
discussed this and the result was to improve the documentation. I don't 
know if it's done yet.

If you still need a general decode function, Cowlib's cow_uri and cow_qs 
still have them. Other third party projects probably do as well.

Cheers,
