SHUTDOWN now does the right thing when append only is on, that is, fsync instead to save the snapshot.

better handling of non blocking connect on redis-benchmark: EPIPE on read does not print an error message now

some change to redis-sha1.rb utility to make it more robust against non-meaningful changes in the dataset

Fixed daemonization when using kqueue/kevent. Now the server initialization is performed *after* the daemonization

use __attribute__ format in sdscatprintf() when the compiler is GCC. Fixed format bugs resulting from the new warnings.

INFO refactored. Stack trace on memory corruption now dumps the same information as the INFO command

log rebuilding, random refactoring, work in progress please wait for an OK commit before to use this version

Minor TODO change with new expiring algorithm description. New expiring algorithm moved since it'll go in 1.1
