make sys/procfs.h mostly work on most archs these structures are purely for use by trace/debug tools and tools working with core files. the definition of fpregset_t, which was previously here, has been removed because it was wrong; fpregset_t should be the type used in mcontext_t, not the type used in ptrace/core stuff.

initial commit of the arm port this port assumes eabi calling conventions, eabi linux syscall convention, and presence of the kernel helpers at 0xffff0f?0 needed for threads support. otherwise it makes very few assumptions, and the code should work even on armv4 without thumb support, as well as on systems with thumb interworking. the bits headers declare this a little endian system, but as far as i can tell the code should work equally well on big endian. some small details are probably broken; so far, testing has been limited to qemu/aboriginal linux.

begin sys/user.h and sys/reg.h fixes for ports aside from microblaze, these should be roughly correct for all archs now. some misc junk macros and typedefs are missing, which should probably be added for max compatibility with trace/debug tools.
