WATCH will now consider touched keys target of EXPIRE command after the WATCH is performed, but not before

Fixed MONITOR output for consistency: now integer encoded values are also formatted like this: "3932"

networking related stuff moved into networking.c

moved more code

more work on layout of source code

SDS instantaneuos memory saving. By Pieter and Salvatore at VMware ;)

cleanly compiling again after the first split, now splitting it in more C files

moving more things around... work in progress

splitting more

Sets split

Hash split

replication split

even more splitting

more splitting

minor change

Fixed deps in makefile and mkreleasehdr.sh script to really take advantage of the new trick to avoid recompilation of redis.c on git sha1 or dirty status change
