Fix warnings about:
- redundant declarations
- a local variable shadowing a global function (dlinfo)
- an old-style function definition (with an empty parameter list)
- a variable that is possibly used uninitialized

Replace uses of the GCC __nonnull__ attribute with the clang nullability
qualifiers. The replacement should be transparent for clang developers as
the new qualifiers will produce the same warnings and will be useful for
static checkers but will not cause aggressive optimizations.
GCC will not produce such warnings and developers will have to use
upgraded GCC ports built with the system headers from r312538.

we need to include it in -legacy or not. Since the ifdef was removed,
this broke building 10.x and older source trees on -current. Restore
just enough of _WITH_GETLINE to allow these older source trees to
still build and properly omit getline() from their -legacy library.
When adding getline(3) and dprintf(3) into libc, those guards were added
to prevent breaking too many ports.
7 years later the ports tree have been fixed, it is time to remove this
FreeBSDism
While here remove the extra parenthesis surrounding dprintf(3)
I'm still not sure why only Pypy runs into the error with the function
typedefs. Fix it anyway.
Use __ssize_t instead of ssize_t for the types; it's possible for the size_t
type to not be visible if at the wrong POSIX_VISIBLE level.
A final (crossing my fingers) follow-up to r299456.

Despite the private namespace, several broken ports depend on the __off64_t
name for the type. Export it exactly the same way off_t and __off_t are
exported.
A follow-up to r299456.

This function is equivalent to fclose(3) function except that it
does not close the underlying file descriptor.
fdclose(3) is step forward to make FILE structure private.

Whenever <sys/cdefs.h> sets __BSD_VISIBLE to non-zero, it also sets
__POSIX_VISIBLE and __XSI_VISIBLE to the newest version supported.
No functional change is intended.
routines provide write-only stdio FILE objects that store their data in a
dynamically allocated buffer. They are a string builder interface somewhat
akin to a completely dynamic sbuf.

P_tmpdir [OB XSI] Default directory prefix for tempnam().
This macro is used in a lot of places in legacy applications,
and is why we see a lot of programs written for e.g. Linux
store volatile temporary files in /var/tmp and not /tmp.

As C1X is close to being released, there is no need to wrap around a
feature that is already part of C90. Most of these files already use
`const' in different placed as well.
dprintf() is a simple wrapper around another function, so we may as
well implement it. But also like getline(), we can't prototype it by
default right now because it would break too many ports.

getline()) cause issues with ports.

move the definition of the type backing FILE (struct __sFILE) into an
internal header.
- Remove macros to inline certain operations from stdio.h. Applications
will now always call the functions instead.
- Move the various foo_unlocked() functions from unlocked.c into foo.c.
This lets some of the inlining macros (e.g. __sfeof()) move into
foo.c.
- Update a few comments.
- struct __sFILE can now go back to using mbstate_t, pthread_t, and
pthread_mutex_t instead of knowing about their private, backing types.

__sFILE. This was supposed to be done in 6.0. Some notes:
- Where possible I restored the various lines to their pre-__sFILEX state.
- Retire INITEXTRA() and just initialize the wchar bits (orientation and
mbstate) explicitly instead. The various places that used INITEXTRA
didn't need the locking fields or _up initialized. (Some places needed
_up to exist and not be off the end of a NULL or garbage pointer, but
they didn't require it to be initialized to a specific value.)
- For now, stdio.h "knows" that pthread_t is a 'struct pthread *' to
avoid namespace pollution of including all the pthread types in stdio.h.
Once we remove all the inlines and make __sFILE private it can go back
to using pthread_t, etc.
- This does not remove any of the inlines currently and does not change
any of the public ABI of 'FILE'.
