Remove bitflags from get_chat_msgs() interface

get_chat_msgs() function is split into new get_chat_msgs() without flags
and get_chat_msgs_ex() which accepts booleans instead of bitflags.

FFI call dc_get_chat_msgs() is still using bitflags for compatibility.

JSON-RPC calls get_message_ids() and get_message_list_items()
accept booleans instead of bitflags now.
