We need casts not just on input but on output, in order to make sure
only the correct bits are visible.

For the macro versions of hton/ntoh, use casts everywhere.

Tweak the hton/ntoh macros so that they are true constants if the
input is a constant expression; this makes them usable in the
preprocessor.

Automatically reformat com32/include/netinet/in.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.

Beginnings of higher-level functions for PXE support.  For now, only
pxe_get_cached_info() is actually supported.
