Memcached 1.6.21

Bugfix and community contribution release. As usual most fixes are for the new \ 
proxy code, along with a lot of community contributed tests for proxy.

A data corruption issue for extstore was fixed. Requires overriding item_age to \ 
a low number of seconds and re-writing the same keys frequently.

Fixes a meta protocol ms bug introduced in 1.6.20 with the s flag being returned \ 
when only asking for the c (cas) flag.

Memcached 1.6.19

Many fixes and new features for the Proxy feature. Rest are small fixes or code \ 
cleanups to the cache daemon. If you're trying out the Proxy code, please \ 
upgrade or continue to track the next branch.

If you use the lru_crawler metadump hash command, specifically the hash mode, \ 
there is a fix for potential slowdowns.

-Werror is no longer the default when compiling. Add --enable-werror to restore \ 
the feature.
