More shrinkage, a bit for ramdisks but mostly for static binaries:

- wrap with #ifndef NO_LOG_BAD_DNS_RESPONSES libc code that uses
  p_class() and p_type() for diagnostics, then add that define to
  libstub to avoid pulling in res_debug_syms.o
- split rcmd() and ruserok() into separate files, as nothing uses both
- split readdir_r() to its own file
- split syslog_r() from syslog(), as the latter needs localtime(); many
  binaries no longer need to pull in all the time code after this; switch
  from usleep() to nanosleep() while we're at it

(The profit of analysis of -Wl,-M,--cref output)

Chops 888kB from /bin and /sbin on i386
