the user supplied buffer. this can be a problem when the user doesn't
supply a full dirent and we corrupt their memory.

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.

readdir_r is not POSIX according to POSIX_SOURCE, bruce says:
> readdir_r() is in the _POSIX_SOURCE section, but is not a POSIX.1-1990
> function. It's POSIX.1-1996 so it should be under a different feature
> test which we don't support yet.
make sure errno is saved so that its contents are cleared unless
necessary.

fixed a minor indentation nit and added a few {}s to make readdir_r
easier on old eyes.

eischen (Daniel Eischen) added wrappers to protect against cancled
threads orphaning internal resources.
the cancelability code is still a bit fuzzy but works for test
programs of my own, OpenBSD's and some examples from ORA's books.
add readdir_r to both libc and libc_r
add some 'const' attributes to function parameters

pointer is 4-byte aligned. On a 64-bit machine it probably should
check that the pointer is 8-byte aligned (eh, Bruce?) 8-)
