1. msync() will take a third argument.
2. remove obsolete xdr_{domainname,mapname,peername} from xdryp.c
3. make __ps_strings extern on setproctitle.c and don't set it to
   a default when it is NULL.
4. make unvis() argument to an int from a char.
5. move timezone() to libcompat
6. move swapon() to libcompat
7. move getdirentries() to libcompat
8. type sanity:
	mode_t: u_int16_t -> u_int32_t
	nlinks_t: int16_t -> u_int32_t
	dev_t: int32_t -> u_int32_t

After all that is committed, libc will go to major version 13, and you'll
*need* to compile and run a new kernel before you build userland.
