5e62671b2f changes for cross build on FreeBSD box. 
- rename some macros and types defined in runetype.h.
 - move declarations of some global symbols to rune.h from runetype.h.
 - make sure the target sources use rune.h and mklocale use runetype.h.
I tested them on FreeBSD-4.6.2 box (./build.sh -m i386 tools).

75e29ba505 some changes around mklocale: 
- clean up cpp directives.
- stop including rune.h from mklocale.
- stop using _BSD_RUNE_T macro.  instead, use int32_t directly in runetype.h.
- move _DEFAULT_INVALID_RUNE to runetype.h.
These were for historical reason on porting rune from FreeBSD,
but it seems that these are no longer reasonable but troublesome
under the current NetBSD build system.
additionally:
- runetype.h -> locale/runetype.h in mklocale, because this might conflict
  to FreeBSD's one.

f60f35f3ab Don't acquire __environ_lock around exec*() calls; nothing requires 
that these calls be thread-safe with respect to the environment, and it
causes serious problems for threaded applications which call vfork() and
exec*() (including indirectly, via popen() or system()).

Acquire and release __environ_lock in the parent in popen() and system() to
play safe and provide the child with a stable environment.

__environ_lock should also have an atfork() handler; still under development.

65ec6ba6e7 Fix lib/20558: 
A dynamically linked program invokes the rtld cleanup routine via
an atexit handler.  This rtld cleanup routine invokes _fini() for
shared libraries, which in-turn invoke __cxa_finalize() with their
DSO handle.  By luck, this happens to work okay for non-threaded
programs, but for a threaded program, this leads to deadlock (sometimes
manifested as an assertion failure, if the program didn't actually
create any threads).

Fixed by teaching __cxa_finalize() that it can be recursively invoked,
adjusting the handler list manipulation accordingly.

(found by... running the regress test!)
* clean up punctuation.
* create a proper frame for the child fn that follows the o32 calling
  conventions.  In particular, leave 4 stack slots that the child
  fn can write on, put the GP above them, and invoke .cprestore
  properly in light of the child fn arg area.  (realized it was a
  problem upon inspection, verified using the regress test compiled
  -O0.)

351f7a02f1 looks like nobody ever seriously tried the _REENTRANT version of this 
code (which, uh, seems the default for a fresh build)...  it wasn't
setting up v1 properly (the instruction to set up v1 was after the
return jump, in "reorder" code...  i.e.  after the end of the function).
That would break error returns from 64-bit syscalls (e.g. checks
in dd and who knows what else) to see if input or output are pipes.
It looks like the non-_REENTRANT version was broken (on the nathanw-sa
branch) in rev 1.9.2.1 and fixed in 1.9.2.2, but the _REENTRANT version
was never fixed, and the broken bits were merged back on to the trunk.

69367db47f Do a similar tuneup on pthread_cond_signal() and

6cca91fc86 Mutex tuneup. 
* Use a double-checked locking technique to avoid taking
   the interlock in pthread_mutex_unlock().

 * In pthread_mutex_lock() and pthread_mutex_trylock(), only store the
   stack pointer, not the thread ID, in ptm_owner. Do the translation
   to a thread ID in the slow-lock, errorcheck, and recursive mutex
   cases rather than in the common path.

 * Juggle where pthread__self() is called, to move it out of the fast path.

Overall, this means that neither pthread_self() nor
pthread_spin[un]lock() are used in the course of locking and unlocking
an uncontested mutex. Speeds up the fast path by 40-50%, and
eliminates about 98% of spinlocks used by a couple of large threaded
applications.

(Still a GET_MUTEX_PRIVATE() in the fast path... perhaps the type
should be in the main body of the mutex).

new enough and nothing in the tree uses barriers so I'm going to let it

fe8e8dad4a More signal rearranging: 
- Signal handlers now simply continue executing the current thread,
   rather than trying to put themselves back on the queue that they came
   from, which was rather fragile. As a result, all callers of
   pthread__block() must be prepared to handle spurious wakeups.

 - When a signal arrives for a thread that is blocked in the kernel,
   note this in another field in pthread_st and set a flag. Process the
   signal and set up the trampoline for the handler *after* the thread
   unblocks, so that both the trampoline and the returned state from
   the kernel are preserved.

 - Factor out some code into a pthread__deliver_signal() routine;
   the signal-taking code in pthread_sigmask() should be able to use this
   soon.

This is still gross, and there are still some terrible MP issues lurking here,
but progress crawls along.

bcbbc4f87e SH5 libc ucontext/lwp support. 
Untested for now, until I get the libpthread stuff done and
an SA userland built.

7dc01dbfab Add some threadlib stubs that are used by X: 
* thr_create() (stub in libc aborts)
* thr_exit() (stub in libc calls exit())
* thr_yield() (stub in libc does nothing)

Also make the libc thr_self() stub not abort.

XXX Should we add thrattr_*() stubs for setting the detach-state?

9b29af3e07 Remove the dummy stack attr routines -- best to catch broken applications 
and fix them to use the proper feature test instead (as has already been
done with the openldap package).

439830cb08 Always allow includes to be installed. This makes it easier for 
people to get straggling ports bootstrapped (pthread.h is required
in order to build libc).

branch.

Ok'd by thorpej.

Closes my PR 19930.
