 At line 75 we make an an an array enough long to contain all urls , but
using as size as many times AV_CAT_SEPARATOR is present on *uri (+1).
 At line 100, instead, we move to the next url (uri += len + strspn()). So,
strings like cat:foo||bar are accepted.

 In the end, we realloc *nodes in order to free all the useless space that
could be allocated due to multiple consecutive AV_CAT_SEPARATOR. But, it's
obviuos that this new size is less than the original size. So, why manage
the case of failure?
