Mainly focus on files that use BSD 3-Clause license.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

It helps to remove _fcntl() call from _ftello() and optimize seek position
calculation in _swrite().

NetBSD, OpenBSD, and Android's Bionic all number the clauses 1 through 3,
so follow suit to make comparison easier.

case of a file descriptor we can't handle, clear the FILE structure's flags

them. Thus, any fd whose value is greater than SHRT_MAX is handled
incorrectly (the short value is sign-extended when converted to an int).
An unpleasant side effect is that if fopen() opens a file and gets a
backing fd that is greater than SHRT_MAX, fclose() will fail and the file
descriptor will be leaked. Better handle this by fixing fopen(), fdopen(),
and freopen() to fail attempts to use a fd greater than SHRT_MAX with
EMFILE.
At some point in the future we should look at expanding the file descriptor
in FILE to an int, but that is a bit complicated due to ABI issues.

plain regular files, i.e. files with __SOPT flag set. Fix it, so ftell(stdout)
always returns the same as lseek(1, 0, 1) now.
NOTE: this bug was in original stdio code

__swrite() and __sseek() to higher level. According to funopen(3) they all
are just wrappers to something like standard read(2), write(2) and
lseek(2), i.e. must not touch stdio internals because they are replaceable
with any other functions knows nothing about stdio internals. See example
of funopen(3) usage in sendmail sources f.e.
NOTE: this is original stdio bug, not result of my range checkin added.

Add a lock to FILE. flockfile and friends are now implemented
(for the most part) in libc. flockfile_debug is implemented in
libc_r; I suppose it's about time to kill it but will do it in
a future commit.
Fix a potential deadlock in _fwalk in a threaded environment.
A file flag (__SIGN) was added to stdio.h that, when set, tells
_fwalk to ignore it in its walk. This seemed to be needed in
refill.c because each file needs to be locked when flushing.
Add a stub for pthread_self in libc. This is needed by flockfile
which is allowed by POSIX to be recursive.
Make fgetpos() error return value (-1) match man page.
Remove recursive calls to locked functions (stdio); I think I've
got them all, but I may have missed a couple.
A few K&R -> ANSI conversions along with removal of a few instances
of "register".
$Id$ -> $FreeBSD$ in libc/stdio/rget.c

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.

just use _foo() <-- foo(). In the case of a libpthread that doesn't do
call conversion (such as linuxthreads and our upcoming libpthread), this
is adequate. In the case of libc_r, we still need three names, which are
now _thread_sys_foo() <-- _foo() <-- foo().
Convert all internal libc usage of: aio_suspend(), close(), fsync(), msync(),
nanosleep(), open(), fcntl(), read(), and write() to _foo() instead of foo().
Remove all internal libc usage of: creat(), pause(), sleep(), system(),
tcdrain(), wait(), and waitpid().
Make thread cancellation fully POSIX-compliant.

points. For library functions, the pattern is __sleep() <--
_libc_sleep() <-- sleep(). The arrows represent weak aliases. For
system calls, the pattern is _read() <-- _libc_read() <-- read().
