All memory allocation and deallocation are accompanied by functions from cplhash.c.
Each time any memory is allocated, an entry is made into a hash table, storing the address.
Each time memory is freed, this entry is removed again. Reallocation uses both procedures.
Function mem_init() initializes the setup.
Function mem_delete() frees all memory with addresses still found in the hash table.
