c1255f7f47 [display] Refactor to avoid implicit framebuffer allocation. 
Preparation to allow other images to be presented to the display.
Separate definitions of display and image formats.
display_get_info no longer provides a framebuffer.
display_get_framebuffer allocates a framebuffer for convenience.

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.

caec70a21b [dev][arm_gic] fix warning in arm64 by adding arm/arm64 specific iframe code 
It's all in service of a LTRACEF, but it's one I use commonly enough to debug
stuff that it's probably worth it. No actual overhead, except what's already
in the first level handlers.

47e06a3f34 [dev][interrupt][arm_gic] Call sm_handle_fiq from platform_fiq 
If WITH_LIB_SM is set, call sm_handle_fiq instead of sm_handle_irq
from platform_fiq. This is needed to allow sm_handle_irq to wake up
a thread instead of switching back to ns from the interrupt handler.

f0fad1590b [init][smp] have secondary init run in arch code up to threading, and complete in secondary thread 
-move the per-cpu initialization of the gic and cortex-a9 timer into an init hook.
  This removes the hard coded call in arm/arch.c
-make sure the timer initialization happens in the pre-threading callback, in case
  a secondary init hook needs the timer.
