ARFlac C library/port Options

[Omy]

Mostly to do with this thread about ARCue.pl. This is my own port/rewrite to C of the ARFlac.pl script which was in turn based off ARCue.pl. As such then credit must go to the authors of ARCue.pl and ARFlac.pl, although the actual C code is my own work.

Basically, this is a C library (and reference program which uses it) which can be used to check a directory of .flac files against the AccurateRip database. See the thread linked above for discussion of it's limitations.

I did a bunch of work on this and thought I should share. It now shows EAC and AccurateRip CRCs, and has some updates including:
- AccurateRip v2 CRC
- vary first-track offset (try "-o32" for the most common non-zero offset)
- attempts to find matches for different drive offsets and disc masters. This is not well-implemented. The algorithm is brute-force and slow. It looks at the AR offset CRC (from a ten-sector window) and does a sliding-window search for a match.
- calculate AR/EAC values using only one disc in a multi-disc set.
- attempts to handle the "4608 samples" pad problem of early EAC+FLAC.
- fixes the "confidence number" bugs in early versions of same

It runs on Linux/GNU, not sure what would be involved in making it work on Windows.
