[PATCH v3 0/5] fix segment fault when parse args

[Chengwen Feng]

The rte_kvargs_process() was used to parse key-value (e.g. socket_id=0),
it also supports to parse only-key (e.g. socket_id). But many drivers's
callback can only handle key-value, it will segment fault if handles
only-key. so the patchset [1] was introduced.
    
Because the patchset [1] modified too much drivers, therefore:
1) A new API rte_kvargs_process_opt() was introduced, it inherits the
function of rte_kvargs_process() which could parse both key-value and
only-key.
2) Constraint the rte_kvargs_process() can only parse key-value.

This patchset also include one bugfix for kvargs of mvneta driver.
