f4084c0544 Bring back nanosleep from the cold.
The addition of the nanosleep syscall was correctly added to
libc/sys/Makefile so that it is renamed as _thread_sys_nanosleep().
This syscall is one of those that libc_r has to re-implement because
the only behaviour is to block the process. So libc_r just ignores the
fact that a nanosleep syscall exists and goes its own way - as it has
done all along .... and now it does again. And now a simple program
can sleep again. Phew.

e91cc88467 Bye bye CPLUSPLUSLIB hack! It's not needed any more.
Don't merge this into -2.2 unless you understand the dependencies on
c++rt0, bsd.lib.mk, and gcc -shared.  I.e., let me do it.

9e19b4c525 Nuke makefiles that duplicate those in libc now that libc is libc_r

7f351fbb21 Use libc makefiles from now on instead of duplicating them in libc_r.
Added Id strings too. It's useful to know who last made a change.

745a12fc30 Make error checking less zealous to handle devices like /dev/null
which don't provide a non-blocking interface.

This is a short term "fix" which changes a half-lose to a half-win.
The thread that accesses a device that does not provide a non-blocking
interface will block for its time slice.

A medium term solution would be to use rfork. A long-term solution
would be some sort of kernel thread/SMP implementation.

Here are the diffs for libc_r to get it one step closer to P1003.1c
These make most of the thread/mutex/condvar structures opaque to the
user. There are three functions which have been renamed with _np
suffixes because they are extensions to P1003.1c (I did them for JAVA,
which needs to suspend/resume threads and also start threads suspended).

I've created a new header (pthread_np.h) for the non-POSIX stuff.

The egrep tags stuff in /usr/src/lib/libc_r/Makefile that I uncommented
doesn't work. I think its best to delete it. I don't think libc_r needs
tags anyway, 'cause most of the source is in libc which does have tags.

also:

Here's the first batch of man pages for the thread functions.
The diff to /usr/src/lib/libc_r/Makefile removes some stuff that was
inherited from /usr/src/lib/libc/Makefile that should only be done with
libc.

also:

I should have sent this diff with the pthread(3) man page.
It allows people to type

make -DWANT_LIBC_R world

to get libc_r built with the rest of the world. I put this in the
pthread(3) man page.  The default is still not to build libc_r.


also:
The diff attached adds a pthread(3) man page to /usr/src/share/man/man3.
The idea is that without libc_r installed, this man page will give people
enough info to know that they have to build libc_r.

5661849d54 keep the libc_r makefiles in step with those from libc
There needs to be a better way of doing this..
preferably we could add another pass to the
normal libc makefiles to do _r versions as well as _p versions

82d29a82b5 Added a new module "uthread_autoinit.cc". This is a small C++ module.
It uses a static constructor to call _thread_init() at program start-up
time.  That eliminates the need for any initialization hooks in crt0.o.

Added a symbol reference in "uthread_init.c", to ensure that the new
module will always be pulled in when the archive version of the library
is used.

In "Makefile.inc", defined CPLUSPLUSLIB, so that the constructor will be
properly invoked in the shared library.

Suggested by: Christopher Provenzano, Peter Wemm, and others.
