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).

benchmarking with different number of LRANGE elements. Ability to change the glue output buffer limit by #define

support for writev implemented but currently ifdef-ed in order to understan why I can't see the improvements expected. Btw code provided by Stefano Barbato

appendfsync parsing in config file fixed. If you benchmarked Redis against different appendfsync options is time to try again ;)
