Adds a new warning to memcheck when realloc is used with a size of 0. For a long time this has been "implementation defined" and so non-portable. With C23 it will become UB. Also adds a switch to turn off the error generation and a second switch to select between the most common "implementation" behaviours. The defaults for this second switch are baked in at build time.
