spa: add spa_json_begin_array/object and relaxed versions

Browse source 
Add spa_json_begin_array/object to replace
spa_json_init+spa_json_begin_array/object

This function is better because it does not waste a useless spa_json
structure as an iterator. The relaxed versions also error out when the
container is mismatched because parsing a mismatched container is not
going to give any results anyway.
