Improve the way that an elf image activator for an alternate word size is included in the kernel. Include imgact_elf.c in conf/files, instead of both imgact_elf32.c and imgact_elf64.c, which will use the default word size for an architecture as defined in machine/elf.h. Architectures that wish to build an additional image activator for an alternate word size can include either imgact_elf32.c or imgact_elf64.c in files.${ARCH}, which allows it to be dependent on MD options instead of solely on architecture.

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).
