I am not much closer to really fixing -p mode but I committed a patch
that make it work for -m0 (stored) files without spawning unrar. I also
found a 15% boost for LE systems with no alignment requirement. Also
fixed a memory leak in set_salt().

I also changed rar2john to pick best candidate from RAR file: Prefer
stored files over compressed, and prefer smaller files over larger.

Like Rich said, 7z might be the best code to use for inflating. But like
all other alternatives I've found, it's object oriented code. This slows
me down considerably, possibly to the point I'll give up :(
