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.

Impact: should deal with memory holes more gracefully

Right now, if we find a memory hole, we simply don't use the memory
beyond that point.  This makes it possible for com32 modules to
use that memory.  After this, we should be able to add relocation
support to allow loading when the memory at 1 MB is unavailable.

Some versions of gcc barf if we have hash-style comments in files when
-std=gnu99 is used.  Remove from assembly files that are subject to
being assembled that way.
