Essentially, this is a literal copy of the code in sys/compat/cloudabi64, except that it now makes use of 32-bits datatypes and limits. In sys/conf/files, we now need to take care to build the code in sys/compat/cloudabi if either COMPAT_CLOUDABI32 or COMPAT_CLOUDABI64 is turned on. This change does not yet include any of the CPU dependent bits. Right now I have implementations for running i386 binaries both on i386 and x86-64, which I will send out for review separately.
