Implemented realloc(), and changed the semantics of malloc(0) to allow
...
for realloc(0) being a valid way to free memory.

We don't actually have a stdio.h header file. Our printf() functions are
...
defined in vsprintf.h. (This may change, since vsprintf.h is a
non-standard name, but for now it's the one to use.)
There should be no need to include vsprintf.h just for DBG() statements,
since include/compiler.h forces it in for a debug build anyway.

Removed incorrect comment; malloc() is inefficient only when the
...
alignment and size are both powers of two, and there's no way to
specify an alignment through the malloc() interface anyway.

Now passes trivial tests. free_memblock() needs neatening up.

Updated memory allocator to improve support for unaligned or partially
...
aligned blocks.
Moved header to include/malloc.h, since we now also provide the
POSIX-like malloc()/free() pair.
Not yet tested.
