To be consistent with the behavior of luci-lib-json, an empty Lua table
should be encoded to an empty JSON list, not an empty JSON object.
To still allow encoding empty JSON objects, the usage of anything other
than a number or a string as a key (for example an empty table or a
function) can be used to force encoding as an object:
json.stringify({}) -- "[]"
json.stringify({[{}] = true}) -- "{}"

Previously, the following caused a segmentation fault:
json.stringify({[{}] = true})
This was caused by lua_tostring() returning NULL for anything but
strings and numbers, letting json_object_object_add crash.
This patch makes jsonc ignore all keys which have no string
representation altogether.
