Summary: Review Request: unrar - RAR archive extractor

I spoke via email to Eugene Roshal about this issue. He was unaware that clamav
had used derived code from their implementation in clamav, under the GPL
license, and stated that he did not grant them permission to do so.

He said that the only way he was willing for such code to be used was with a
clause like the following:

"The unRAR sources cannot be used to re-create the RAR compression algorithm, 
 which is proprietary. Distribution of modified unRAR sources in separate form 
 or as a part of other software is permitted, provided that it is clearly
 stated in the documentation and source comments that the code may
 not be used to develop a RAR (WinRAR) compatible archiver."

Unfortunately, such a restriction conflicts directly with the GPL, and is a

This code cannot go into Fedora as is. All RAR v3.x support would need to be
stripped out, before it could be considered. Given that most RAR files are RAR
v3, that severely limits the usefulness of this application.

In addition, we will need to strip the RAR v3 code out of clamav.
