New port of mpg123.

[QuzarDC]

Perhaps a better alternative for mp3 backend than #104 as it's not bound by integer math.

Needs examples.

mpg123-stream.zip

works fine, here is an example.

Getting a weird issue, if I change my mpg123 example to read from /pc over bba it fails, but /rd and /cd work fine with my example and with DCSinge.

I get this error message, i added in some logging code that shows I can access the file over /pc just fine.
DCSinge mpg123 snd_stream test
START exits.

If you have a serial cable might try over that to be sure it's not the generic /pc vfs. Quite sure though that it's a side effect of this: KallistiOS/KallistiOS#1176 Where dcload-ip doesn't play well with audio dma.

Yeah good chance it is related to #1176

Yeah I have my original one from 20 years ago(Lik Sang rip), but no serial port on my computer, unfortunately.

I redid my example and got /pc working, by creating my own file reader and seeker implementation using fs_open/read/seek/close , it seems to work as a cdi as well from emulator :)

    err = mpg123_replace_reader_handle(g_mpg,
                                       kos_reader_read,
                                       kos_reader_seek,
                                       kos_reader_cleanup);

mpg123-stream-V2.zip

so not sure if you want to pull that into the internals implementation of the new kos-ports mpg123, or not you can add my example if wanted.
