/*
* This is a central memory allocation place for the Toolbox core module.
* A doubly-linked list of all allocated blocks is kept (maybe remove this
* if using too much memory!).
* To enable debugging of memory allocation, the calling functions should be
* compiled without -ff, so that fn names are in the code area. Compile
* this code with -DDEBUG_MEMORY.
* Memory tracing is turned on by setting the letter 'm' in the central
* debug string (got by calling debugging('m')).
*
* Calling code will always call the debugging versions eg
* b = memory_allocate (1024, &fn, "some extra info");
* Macros ensure the debugging code is removed.
