adding (weak definitions to) stubs for some of the pthread
functions. If the threads library is linked in, the real
pthread functions will pulled in.
Use the following convention for system calls wrapped by the
threads library:
__sys_foo - actual system call
_foo - weak definition to __sys_foo
foo - weak definition to __sys_foo
Change all libc uses of system calls wrapped by the threads
library from foo to _foo. In order to define the prototypes
for _foo(), we introduce namespace.h and un-namespace.h
(suggested by bde). All files that need to reference these
system calls, should include namespace.h before any standard
includes, then include un-namespace.h after the standard
includes and before any local includes. <db.h> is an exception
and shouldn't be included in between namespace.h and
un-namespace.h namespace.h will define foo to _foo, and
un-namespace.h will undefine foo.
Try to eliminate some of the recursive calls to MT-safe
functions in libc/stdio in preparation for adding a mutex
to FILE. We have recursive mutexes, but would like to avoid
using them if possible.
Remove uneeded includes of <errno.h> from a few files.
Add $FreeBSD$ to a few files in order to pass commitprep.

telldir positions. This will allow (future) locking on a
per-DIR basis (for MT-safety). For now, this change does
the following:
o Remove the hash table from telldir.c. Recode to use queue
macros.
o Remove 'const' from 'telldir(const DIR *)'.
o Remove 'register' variables as suggested in a recent
thread.

a NULL argument. Some programs change the contents of the argv
array, typically to remove some special arguments. They shorten
argv by storing a NULL where an argument pointer used to be. Such
programs core dumped if they called setproctitle(), because it
would try to apply strlen() to a NULL pointer.

on freebsd, but is somewhat risky practice (and causes trouble when
porting to other OS's).
