Before the patch, a call to rte_kvargs_tokenize() resulted in a call to
strdup() to allocate a modifiable copy of the argument string. This
string was never freed, excepted in the error cases of
rte_kvargs_tokenize() where rte_free() was wrongly called instead of
free(). In other cases, freeing this string was impossible as the
pointer not saved.
This patch introduces rte_kvargs_free() in order to free the structure
properly. The pointer to the duplicated string is now kept in the
rte_kvargs structure. A call to rte_kvargs_parse() directly allocates
the structure, making rte_kvargs_init() useless.
The only drawback of this API change is that a key/value associations
cannot be added to an existing kvlist. But it's not used today, and
there is not obvious use case for that.
