There shouldn't be any need to export `MAX_DEV_NAME_LEN` from the unixlib (just define it in `coreaudio.c`).

Have a look how the alsa driver does this.  Basically move `dev_name` to the end of the struct, and allocate enough space in `AUDDRV_GetAudioEndpoint()` once you know the length of the device name.
