Two important fixes to append only file: zero length values and expires. A pretty neat new test to check consistency of randomly build datasets against snapshotting and AOF.

Fixed some subtle bug in the command processing code almost impossible to spot in the real world, thanks to gcov

Changed the reply of BGSAVE and BGREWRITEAOF from +OK to a more meaningful message that makes the user aware of an operation that just started and is not yet finished.

Set the master->slave logical client as authenticated on creation, so that if the slave requires a password replication works anyway

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

a bit more verbose -ERR wrong number o arguments error, now gives info about the command name causing the error

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.

Fixed issued #85 (getDecodedObject: Assertion 1 != 1 failed. While sorting a set), added a smarter assert() function to dump the stacktrace, provided a macro to initalize Redis objects on the stack to avoid this kind of bugs.

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

ifdefs added to use kevent on Free Open and Net BSD as well. INFO and ae.c modified in order to report the multiplexing API in use

Enabled object encoding for multiple keys in MSET. Added a test for memory leaks in test-redis.tcl when running on Mac OS X

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

DEBUG RELOAD implemented, and test-redis.tcl modified to use it to check for persistence consistency.

ae.c now supports multiple polling API modules, even if only ae_select.c is implemented currently. Also adding and removing an event is now O(1).
