35173b1fce Partially revert 1.110: Use makecontext again until the problems with 
_lwp_makecontext are solved.

49931fb2d8 Restore PTHREAD__ASM_RASOPS for alpha (from _context_u.S), that was 
lost in previous cleanup.

ok by ad@.

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, 
I guess not well enough.

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.

18e73e1ebe Replace semid_t with intptr_t. No function change. This is a libc/kernel 
private interface and so the name change should not affect any third

struct mcontext != struct reg on sh3.

844fcfc979 make PTHREAD__COMPAT=1 
Builds a libpthread that can be dropped into a NetBSD 2/3/4 chroot.

This makes threading work in the chroot when using a NetBSD 5 kernel, no
other modifications required.
