This commit attempts to fix one of the items in nodejs#4641, which was to remove a TODO comment from env.h regarding the naming of the ares_task_t struct. Also, the struct ares_task_list was renamed to node_ares_task_list following the same reasoning that is does not belong to the c-ares API.

malloc(0) and realloc(ptr, 0) have implementation-defined behavior in that the standard allows them to either return a unique pointer or a nullptr for zero-sized allocation requests. Normalize by always using a nullptr. - Introduce node::malloc, node::realloc and node::calloc that should be used throught our source. - Update all existing node source files to use the new functions instead of the native allocation functions.

Change `Malloc()/Calloc()` so that size zero does not return a null pointer, consistent with prior behavior.
