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.

enable kqueue/kevent only for Mac OS X 10.6.x as it seems that 10.5.x has a broken implementation of this syscalls.

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.
