URL encoded Targetnames

Assume target names are URL encoded with '%' as the special character.

Any sequence of '%' followed by two bytes in the target name will be replaced
with the byte that the second two bytes represent in hexadecimal.

Example
iqn.ronnie.test%3A1234
will be translated to iqn.ronnie.test:1234
