* src/aiff.c src/w64.c src/wav.c
Do not return a header parse error when the log buffer overflows.
Continuing parsing works even on files where the log buffer does overflow.
This avoids a bug on some weirdo WAV (and other) files.
* src/common.h src/sndfile.c
Remove SFE_LOG_OVERRIN error and its associated error message.
