Infrastructure tweaks to allow having both an Elf32 and an Elf64 executable handler in the kernel at the same time. Also, allow for the exec_new_vmspace() code to build a different sized vmspace depending on the executable environment. This is a big help for execing i386 binaries on ia64. The ELF exec code grows the ability to map partial pages when there is a page size difference, eg: emulating 4K pages on 8K or 16K hardware pages. Flesh out the i386 emulation support for ia64. At this point, the only binary that I know of that fails is cvsup, because the cvsup runtime tries to execute code in pages not marked executable. Obtained from: dfr (mostly, many tweaks from me).

Add CTASSERT()'s to check that the sizes of our replicas of the 32 bit structures come out the right size. Fix the ones that broke. stat32 had some missing fields from the end and statfs32 was broken due to the strange definition of MNAMELEN (which is dependent on sizeof(long)) I'm not sure if this fixes any actual problems or not.
