snprintf buffer overflow after f42b8e3aac with pipewire versions containing 0e847c97

[haasn]

In pipewire commit 0e847c97 the jack port name size was bumped up to 513 (256+256+\0 byte), which is above the hard-coded limit of 512.

Possible solutions:

1. Reverting the offending commit and simply live with the fact that your toaster running gcc 0.8-pre-alpha will not be able to compile nsm.
2. Switch to using malloc to avoid the issue with dynamically sized arrays.
3. Bump up the hard-coded limit to at least 513 and also add a safety cap to prevent this from buffer overflowing again.

I've just bumped into the same issue. The fix involves the jackpatch.c source only.
