Fix formatting.

Add strndup(3) to libc.

$MidnightBSD$

Correct misleading documentation.

Add NetBSD efun(3) functions...

esetfunc, easprintf, efopen, ecalloc, emalloc, erealloc, estrdup, estrlcat, estrlcpy, evasprintf

Some code in the tree already includes this such as fsck and rcorder. This will make NetBSD code porting easier.  Note our libutil uses libutil.h instead of util.h.

As discussed on freebsd-threads@freebsd.org, a libpthread bug exists that this patch by Peter Edwards Corrects.

Here is a summary:

I've a problem when a process uses:
       libpthread
       detached threads
       mixed bound/unbound threads
       suspended threads  (a la pthread_resume_np())

whereby some newly created suspended threads don't get scheduled.
I think I've tracked it down, so if someone could review the
reasoning, I'd be grateful.

Newly launched threads have a "struct pthread" that may be allocated
from a freelist of GCed threads. Apparently, when detached threads
enter the GCed list, they can still have the "active" flag set on
them. Later, this causes problems when this thread is recycled and
resumed, because _thr_setrunnable_unlocked() doesn't add it to a
run queue.

thr_cleanup can be called either from the bound-threads scheduler,
or the unbound scheduler. One callsite clears "active", "needswitchout",
and "lock_switch" to zero before the call. The other callsite just
clears "check_pending". I think these flags are all either bound-thread
or unbound-thread specific, and that there was an unintended
assumption that the thread would remain with the same "boundedness"
after being recycled, which isn't neccessarily the case. (Or another
way - the idea was that there was no need to clear the "active"
flag on a bound thread, as its only used for unbound threads, but
a GCed bound thread might be recycled into an unbound thread)

Given that, it seems correct to clean up the thread the same way
for both cases, and just move that code into thr_cleanup.

Only catch SIGINFO when LIBPTHREAD_DEBUG is defined in the environment.

Eliminate a race condition in timed waist (cv, mutex, sleeps).

Don't forget to init a TAILQ before using it.

Allocate a thread's tcb last so it is easier to handle failures to malloc() siginfo.

Include needed headers obtained through pthread.h
