Replace copied (from rsync) checksum code by adler32() from zlib
The weak checksum code that is included in libglusterfs has initialy been copied from the rsync sources. Instead of maintaining a copy of a function, we should use a function from a shared library. The algorithm seems to be Adler-32, zlib provides an implementation. The strong checksum function has already been replaced by MD5 from OpenSSL. It is time to also remove the comments about the origin of the implementation, because it is not correct anymore.
