Fix several warnings for -Wmissing-prototypes (part 2)

* i386/i386/io_map.c: code is unused.
* i386/i386/io_perm.c: include mig prototypes.
* i386/i386/mp_desc.c: Deleted interrupt_stack_alloc since it is not
  used.
* i386/i386/seg.h: Moved descriptor structs to i386/include/mach/i386/mach_i386_types.h
  as that represents the interface types for RPCs.
  Defined aliases for real_descriptor since those are used by the i386 RPCs. Inlined many
  functions here too and removed seg.c.
* i386/i386/seg.c: Removed. All the functions are inline now.
* i386/i386/trap.c: Use static.
* i386/i386/trap.h: Define missing prototypes.
* i386/i386/tss.h: Use static inline for ltr.
* i386/i386/user_ldt.c: Include mig prototypes.
* i386/include/mach/i386/mach_i386.defs: Define real_descriptor_t types
  since those are used in the RPC definition. Now both prototypes and
definitions will match.
* i386/include/mach/i386/mach_i386_types.h: Move struct descriptor
  from seg.h since we need those for the RPC interfaces. Removed include
  of io_perm.h since it generates circular includes otherwise.
* i386/intel/pmap.c: pmap_map is unused. Added static qualifier for
  several functions.
* i386/intel/pmap.h: pmap_update_interrupt declared for non-SMP and SMP.
