The sequencer API is totally recoded with the style of "encapsulation" in other api. The structure becomes opaque and accessed only via functions. Other changes: - There is no longer group in client and port info. - snd_seq_query_subs_t is renamed to snd_seq_query_subscribe_t. - snd_seq_delete_port takes only the port id argument instead of port_info structure. - snd_seq_input/output_buffer_size are renamed as snd_seq_get_input/output_buffer_size. Similarly snd_seq_resize_input/output_buffer are renamed as snd_seq_set_input/output_buffer_size. - snd_seq_get_named_queue is renamed to snd_seq_query_named_queue. - Sync codes are removed temporarily from API. - Subscription conditions are accessed via the corresponding functions. convert_time is named now as time_update. - snd_seq_get/set_queue_owner are removed. Use snd_seq_get/set_queue_info instead. - Instrument put/get/remove structure is unified as snd_instr_header_t.
