Make the default $init value for incrWithInit() be $value. This is far less suprising and also makes the operation easier to replicate without conflicts. Make decr() definitions more explicit since various cache drivers do not handle negative incr() values (e.g. memcached). Change-Id: I2b8d642656cc91c841abbd7a55d97eba101b027a
