CPUID functions were apparently broken when made PIC-safe; clean up
and fix.

Do the actual idling in protected mode.  This both allows PM code a
more efficient interface, but also handles bugs in HVM implementations
which don't handle HLT in real mode.

Automatically reformat com32/include/sys/cpu.h using Nindent.

Do this for all files except HDT, gPXE and externally maintained
libraries (zlib, tinyjpeg, libpng).

Introduce a new "COM32R" format, which is exactly like COM32 except
that they contain position-independent code.  Therefore, the core can
load them at any sufficiently aligned address; by protocol select 4K
as the alignment.

<sys/cpu.h> already has most of the CPUID inlines, put them all there.
<cpuid.h> still have structures for the code that really should be
librarized at some point.
