The midifile library used by the playmidi1 program dates from 1989, and
used pre-ANSI function definitions and prototypes. GCC 15 now defaults
to C23 where () means the same as (void) in prototypes, which causes
type mismatch errors.
Update the code to use ANSI function definitions and prototypes, so
it'll compile happily as anything from ANSI C to C23. This revealed that
playmidi1's do_tempo had the wrong argument type, so correct that as
well.

It's a fast fix. The better way is to fix midifile.h or remote this example

config.h may contain defines like _FILE_OFFSET_BITS which influence
the system wide include files (off_t types, open -> open64 function
usage etc.).

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.

OK, the attached is the patch to alsa-driver and alsa-lib.
It will really violate the source/binary compatibility as
I wrote :-p
It includes:
- change of event data for accessing Timer Port
- new middle-level functions for sequencer in alsa-lib
- some comments / fixes
The test programs in alsa-lib (playmidi1, aconnect, aseqnet)
were rewritten to use the new functions above.
I included also a patch to pmidi-1.2.2.
