ABI changes:
  Add d_type to struct dirent
  Fix f_files/f_ffree bug in struct statfs (they are always ino64_t)
  Adjust struct statfs or remove statfs/fstatfs outright
    Implement statfs[64] in terms of statvfs[64]
      Use sysfs to translate fsname into fstype

ptrace details:
  /proc/PID/{as,ctl,status,sigact,psinfo}
  PTRACE_PEEK, PTRACE_PEEKDATA: pread(as)
  PTRACE_PEEKUSR: user_t
  PTRACE_POKETEXT, PTRACE_POKEDATA: pwrite(as)
  PTRACE_POKEUSR: user_t
  PTRACE_CONT:
  PTRACE_KILL:

  ctl is managed via PC* constants (e.g. PCSTRACE)
    write command (long) followed by struct

These are solaris extensions that we should implement:
  _sharefs
  _cladm (sys/cladm.h)
  exportfs, nfs_getfh, nfssvc [SYS_nfssys] (sys/nfssec.h) [maybe not]
  lgrpsys
  gethomelgroup
  _ttyname_dev
  pthread_rwlock_reltimedrdlock_np
  pthread_rwlock_reltimedwrlock_np

Insert into headers:
  resolvpath (unistd.h)
  issetugid (unistd.h)
  getvmusage (sys/vm_usage.h)
  str2sig, sig2str (signal.h)
  sigsend, sigsendset (signal.h)
  getexecname (stdlib.h)
  lltostr, ulltostr (stdlib.h)
  fdwalk, closefrom (stdlib.h)

INVALID_NOT_TERMINATED_TD_P expects to succeed on terminated threads

More __builtin_expect's

More clocks in pthread_condattr_setclock

Use timer_* syscalls

Fix forward.c to include mutex_* and thr_main
  thr_main should return -1 when libpthread.so is not linked in
