2eb32a4369 [style] mass reformat all the non external code to 4 space indents 
Ran everything through scripts/codestyle.space, which uses astyle
to generally follow K&R style.

Biggest non whitespace change is pulling brackets down on function
declarations, which I'm pretty ambivalent about, but astyle insists
on taking a stance

491e47fbc6 [linker] align special sections on native pointer bounary 
This fixes a bug in x86-64 where it was trying to default align
input sections on 16 byte boundaries, which was screwing up the
padding between structures.

114a350e55 [linker] align all the special sections on 8 byte boundaries, remove x86-64 hack 
A bit overkill for 32bit machines, but aligning all the special data structures
on 8 byte boundaries removes any special case for 64bit machines.

0e1ce411ba [make] add ability to set EXTRA_LINKER_SCRIPTS in modules 
This allows for individual modules to extend the main linker script,
primarily to add their own sections to interate over.
Remove the main shared_* linker scripts.

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.

2809f91084 [app][loader] Load blobs and run elf via tftp into SDRAM 
Introduces two commands:
   load any <filename>
   load elf <filename>

Then from another system in the network you can:
   tftp -i <ip-addr> put <filename>

Which for the 'any' case just loads the file into DRAM and for the 'elf'
case it parses the file and if correct it spawns a thread to run the
entrypoint.

ac406077ae [app][inetsrv] add tftp server. 
Only allows writting files. Needs a per-file handler to be wired and
provisionally has a test handler wired to "tftp_test.txt" which prints
the crc32 of the complete file pushed via
   tftp -i 192.169.0.xx tftp_test.txt

Some error conditions are yet to be fully handled.
