/*
PROGRAM
malloc(), free(), realloc()
AUTHOR

Modified by Ceriel Jacobs, Free University, Amsterdam,
to make it faster
VERSION
$Header$
DESCRIPTION
This is an independent rewrite of the malloc/free package; it is
fast and efficient. Free blocks are kept in doubly linked lists,
list N holding blocks with sizes between 2**N and 2**(N+1)-1.
Consequently neither malloc nor free have to do any searching:
the cost of a call of malloc() (or free()) is constant, however
many blocks you have got.
If you switch on the NON_STANDARD macro (see param.h) every block
costs 2 pointers overhead (otherwise it's 4).

/*
There is an organisational problem here: during devellopment
I want the package divided into modules, which implies external
names for the communication. The only external names I want in
the finished product are malloc, realloc and free. This requires
some hanky-panky.
