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.

interface was based on a draft version of POSIX whereas the final
(1996) version of POSIX specified that the error is returned.
While I'm here, fix getlogin_r so that it works for more than just
the first time it's called.

quitting every time. The way to free a CIRCLEQ was to loop until
the current == current->head, but the way to free a TAILQ is to loop
until current->head == NULL.
In any case, the CORRECT way to do it is a loop of TAILQ_EMPTY() checks
and TAILQ_REMOVE()al of TAILQ_FIRST(). This bug wouldn't have happened
if the loop wasn't hard-coded...
There may be more bugs of this type from the conversion.
