35ebee0e40 [merge] branch 'heapswitch' 
This picks up the major work of allowing multiple heap implementations
and enable dlmalloc as an alternate heap to the simple existing one
(now called 'miniheap').

Also added a novm page allocator for memory management on systems too small
or missing an mmu to have a vm. Not much more than a simple bitmap allocator
that the heap pulls from. Allows for other heaps and/or users of physical
memory to coexist and span multiple banks of memory.

3b2d7a268b [make] remove the need for a module to manually add $(LOCAL_DIR)/include to the global include path 
Pretty much every module in the system was already doing it, so do it
automatically.

36c7735533 [libc][stdio] cleanup printf definition and clients 
Move implementation to stdio.c to sit next to the other
stdio definitions that use the debug output functions. Keep
the declaration of it, though, in printf.h to sit next to
sprintf, etc.

Don't include printf.h directly in other places, rely on stdio.h
to properly pull in these functions.

2ae06216b1 [libc] fix printf edge case with signed leading digits 
Fixes specific case as in printf("%03d\n", -2), which
would put the sign digit after the leading zeros.

Make sure the sign bits are before any leading zeros or spaces.

Add test case for this.

-Change INCLUDES -> GLOBAL_INCLUDES
-Remove -I prefix
