Use recallocarray() to avoid leaving detritus in memory when resizing
buffers. We don't bother doing this for objects containing pointers,
but focus on controllable data.

After read errors, fgetln(3) sometimes succeeded (returning non-NULL)
and failed (setting errno and ferror(3)) both at the same time.
That's a bad idea in general, and here in particular since
returning partial lines was neither reliable (sometimes, you
got NULL anyway) nor predictable (almost always, the line would
be truncated long before the actual read error).
Instead, on read failure, fail properly and always return NULL.
Issue found in a discussion with Andrey Chernov <ache at freebsd dot org>
who finally agreed to move FreeBSD into the same direction.
The fix is joint work with and OK by millert@.

Add framework for resolving (pun intended) libc namespace issues, using
wrapper .h files and asm labels to let internal calls resolve directly and
not be overridable or use the PLT. Then, apply that framework to most of
the functions in stdio.h, string.h, err.h, and wchar.h. Delete the
should-have-been-hidden-all-along _v?(err|warn)[cx]? symbols while here.

Fix the handle locking in stdio to use flockfile/funlockfile
internally when and where required. Macros in <stdio.h> are updated
to automatically call the underlying functions when the process is
threaded to obtain the necessary locking. A private mutex is added
to protect __sglue, the internal list of FILE handles, and another
to protect the one-time initialization. Some routines in libc that
use getc() change to use getc_unlocked() as they're either protected
by their own lock or aren't thread-safe routines anyway.
