upstream_hash 0.3

[Evan Miller]

Changes in upstream_hash 0.3:

  *) Change: Hashing and failover are compatible with PECL Memcache (based on 
CRC-32).

  *) Change: "hash_method" directive removed.

Note that the hashing algorithm is incompatible with old versions of 
upstream_hash. I thought that the previous "crc32" algorithm was PECL Memcache/
libmemcache compatible, but that turned out not to be the case. Now it really 
is compatible (and the new test suite proves it!).

I removed the old "simple" hash method (as well as the hash_method directive) 
because it offers no benefits or compatibility compared with the new default 
hash method.
