Log Message:
Updated mpg123 to 1.25.5.

1.25.5
------
- Avoid another buffer read overflow in the ID3 parser on 32 bit platforms
  (bug 254).

1.25.4
------
- Better configure checks for i?86-apple-darwin (bug 253).
- libmpg123:
-- Prevent harmless call to memcpy(NULL, NULL, 0).
-- More early checking of ID3v2 encoding values to avoid bogus text being
   stored.

1.25.3
------
- libmpg123:
-- Better checks for xrpnt overflow in III_dequantize_sample() before each
   use, avoiding false positives and catching cases that were rendered
   harmless by alignment-enlarged buffers.
