4035b6ee7d Improve wording describing the behavior of the attributes argument, and 
add reference to pthread_attr(3), as requested in PR 42871. The text
added is different from but based on a suggestion by Matthew Mondor.

ebe1a1a443 Use a list with the mutex type. Note, from the standard, that recursive 
mutexes should be avoided when condition variables are used.

f395ce5a84 Use similar markup than in pthread_mutex_init(3) etc. with the initializer 
macro. Improve wording slightly.

years ago, but if there are better ones, please feel free to add those.)

85ddadbfdc Don't just look only at the first element in the deadqueue to find lwp's 
to reuse, because if we lose the race with the kernel we are never going
to reuse any elements. Look in the whole list instead.
XXX: should be pulled up to 5.x

61cac435e4 - Convert from makecontext() -> _lwp_makecontext(). 
- Rely on _lwp_makecontext() to set up the thread identity register.
  This is not currently done (a bug), nor does libpthread use the
  threadreg yet. I'm doing this so it the code can be used by the
  person working on TLS to verify that their threadreg code is working.

8b5179c21c Add CAVEATS section: 
Due to limitations in the current pthread implementation, makecontext(3)
and sigaltstack(2) should not be used in programs which link against
libpthread (whether threads are used or not).

Wording from drochner@ and ad@

Bump date for man pages.

Add note in libpthread/README so it's not forgotten to update the man
pages when the problem is fixed.

f1c955a1b2 Fix the comparision function used by the red-black tree global thread list 
implementation:
-don't return a difference, this can overflow
-don't try to substract typed pointers which don't belong to the
 same object, this gives undefined results

This fixes instabilities of programs which use more than a handful
of threads, eg spuriously failing pthread_join().

7de9da978b Revert the _lwp_ctl which is causing problem. I did test this locally,

5c670ea686 - Make the threadreg code use _lwp_setprivate() instead of MD hooks. 
XXX This must not be enabled by default because the LWP private mechanism
  is reserved for TLS. It is provided only as a test/demo.

  XXX Since ucontext_t does not contain the thread private variable, for a
  short time after threads are created their thread specific data is unset.
  If a signal arrives during that time we are screwed.

- No longer need pthread__osrev.

- Rearrange _lwp_ctl() calls slightly.
