I'd say to do this in two steps: a) moving the definitions of the current be32toh/etc to a new src/guestfs-byteswap.h (internal), making use of it b) add the proper definitions needed on Mac OS X Thanks, -- Pino Toscano

The byteorder detection macro for the rijndael algorithm doesn't work for systems that are building for multiple architectures, such as Darwin. This was the change that was needed to rijndael.c to get the macros building properly in such a situation. It seems to be a little more reliable than the existing system.

virtio 1.0 makes all memory structures LE, so we need APIs to conditionally do a byteswap on BE architectures. To make it easier to check code statically, add virtio specific types for multi-byte integers in memory. Add low level wrappers that do a byteswap conditionally, these will be useful e.g. for vhost. Add high level wrappers that will (in the future) query device endian-ness a...
