Remove the write handler only if there are no longer objects in the output queue AND if the static buffer is empty. This bug was the cause of a possible server-stop-responding-to-client bug under some specific work load. Thanks to Pieter Noordhuis for spotting and fixing it.

Auto rewrite integer overflow fixed. Thanks to Gaurav for finding it (see issue 602 on google code), and Pieter Noordhuis for tracing it.

prepareForShutdown() fixed for correctness regarding what to do with AOF and RDB persistence on exit.

Added a 'runtest' script that is responsible to check if Tcl is available and run the test. This is invoked from Makefile as well.

top level Makefile now just a proxy. Doing make clean inside src now does a full clean including deps, not just Redis source. Thanks to Pieter for the top level Makefile proxy trick.

Take a pointer to the relevant entry of the command table in the client structure. This is generally a more sounding design, simplifies a few functions prototype, and as a side effect fixes a bug related to the conversion of EXPIRE -1 to DEL: before of this fix Redis tried to convert it into an EXPIREAT in the AOF code, regardless of our rewrite of the command.

don't process EXPIRE with negative TTL or EXPIREAT with time in the past if we are a slave too (see http://groups.google.com/group/redis-db/browse_thread/thread/5a931fefb88b16d5). Also propagate it as DEL.

They will be expired (and a DEL will be logged) after the loading is done
instead.

childrens -> children in INFO output field names. This is a backward incompatible change, but really a minimal one.
