 * RedisModule_Callc, etc implementations, that allow Redis better control and
 * reporting over allocations per module.
 *
 * You should include this file in all c files AS THE LAST INCLUDED FILE
 *
 * This only has effect when when compiling with the macro REDIS_MODULE_TARGET
 * defined. The idea is that for unit tests it will not be defined, but for the
 * module build target it will be.
