syslog(3) if we are a priveleged program (sshd, su, etc.).
- Make syslogd open an additional socket /var/run/logpriv, with 0600
permissions.
- In libc, try to use this socket.
- Do not loop forever if we are using this socket (partial backout of 1.31)

the GPT partition on i386 and adm64 as type=gpt, subtype=0 and with the
sname set to the UUID. This prevents sysinstall from bombing out. This
also makes sure the GPT partition shows up in sysinstall so as to avoid
accidental "clobberage".

While I'm here, straighten out a misleading comment about GNU-compatible
sparse file handling.
put DEAD thread on GC list, this closes a race between pthread_join
and thr_cleanup.
2. Introduce a mutex to protect tcb initialization, tls allocation and
deallocation code in rtld seems no lock protection or it is broken,
under stress testing, memory is corrupted.

no userland locks are heald, the dead thread lock can no longer protect
access to it. Therefore, instead of using an if (!dead)...else clause
after walking the active threads list test the thread pointer before
deciding not to walk the dead threads list. If the thread pointer is null
it means it was not found in the active threads list and the dead threads
list should be checked.
2. Do not free the stack of a thread that is not marked dead. This is the
2nd and final part of eliminating the race to free a thread's stack.
