Luoqi Chen 7a2bb3b800 Some reorganization of sysarch() interface:
1. Move definitions of struct i386_*_args to the header file sysarch.h,
   since they are part of the sysarch API. struct i386_get_ldt_args and
   i386_set_ldt_args were identical, therefore make them into one
   struct i386_ldt_args. Libc should use these definitions as well.
2. Return a more sensible EOPNOTSUPP for unknown operations.
