cdf4f0e426 In the NOTYET code path when a process forks, the remaining
child thread goes back to system scope rather than process
scope.  This allows an ensuing exec() to actually work.

This change was made a year ago here, but I "forgot" to
commit it :(

e3b0678e20 Clean bound and non-bound pthread structures consistently before
they become candidates for reuse.  Without this fix, some of the
state from a thread structure's previous incarnation could interfere
with its new one. Specifically, a non-bound thread started as
"suspended" (see pthread_attr_setcreatesuspend_np()) might not get
scheduled at all when resumed, as the "active" flag would be set
spuriously.

9dfca48522 Stylize:
o  avoid using a global register variable.
o  redefine struct ia64_tp as a union. We don't have to get to the
   fields themselves. We just need it to be of the right size with
   the right alignment.

657a4c30ac The ucontext is 16-byte aligned, which means that struct tcb is
16-byte aligned. Consequently, struct tcb is a multiple of 16
bytes in size. We need to make sure there's no padding after
struct ppc32_tp. We do this by explicitly adding the necessary
padding in front of it.

7b9c5e1df6 o Remove a cruft prevented libpthread sigaction(2) wrapper to
do its work for SIGINFO.  Always install libpthread signal handler
wrapper for SIGINFO even if user SIG_IGN's or SIG_DFL's it.

SIGINFO has a special meaning for libpthread: when LIBPTHREAD_DEBUG
enviroment variable defined it is used for dumping an information
about threads to /tmp/.

cc69a08fbf Add compatibility symbol maps. libpthread (.so.1 and .so.2)
used LIBTHREAD_1_0 as its version definition, but now needs
to define its symbols in the same namespace used by libc.
The compatibility hooks allows you to use libraries and
binaries built and linked to libpthread before libc was
built with symbol versioning.  The shims can be removed if
libpthread is given a version bump.

3668a2e494 In preparation for a new malloc implementation:
* Add posix_memalign().

  * Move calloc() from calloc.c to malloc.c.  Add a calloc() implementation in
    rtld-elf in order to make the loader happy (even though calloc() isn't
    used in rtld-elf).

  * Add _malloc_prefork() and _malloc_postfork(), and use them instead of
    directly manipulating __malloc_lock.

9105db3d27 For the ``#ifdef NOTYET'' code that allows calling non-async-safe
functions in the child after a fork() from a threaded process,
use __sys_setprocmask() rather than setprocmask() to keep our
signal handling sane.  Without this fix, signals are essentially
ignored in said child and things such as protection violations
result in an endless busy loop.

07adfc3d98 Modify the code path of the ifdef NOTYET part of _kse_single_thread():
o  Don't reinitialise the atfork() handler list in the child.  We
   are meant to call the child handler, and on subsequent fork()s
   should call all three functions as normal.
o  Don't reinitialise the thread specific keyed data in the
   child after a fork.  Applications may require this for context.
o  Reinitialise curthread->tlflags after removing ourselves from
   (and reinitialising) the various internal thread lists.
o  Reinitialise __malloc_lock in the child after fork() (to balance
   our explicitly taking the lock prior to the fork()).

With these changes, it is possible to enable the NOTYET code in
thr_kern.c to allow the use of non-async-safe functions after
fork()ing from a threaded program.
