Add an implementation of open_memstream() and open_wmemstream(). These
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.

with the respective regression test.

Implement xlocale APIs from Darwin, mainly for use by libc++. This adds a
load of _l suffixed versions of various standard library functions that use
the global locale, making them take an explicit locale parameter. Also
adds support for per-thread locales. This work was funded by the FreeBSD
Foundation.

Please test any code you have that uses the C standard locale functions!

Add dprintf() and vdprintf() from POSIX.1-2008. Like getline(),
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.

Retire the __fgetcookie(), __fgetpendout(), and __fsetfileno() accessors
as we aren't hiding FILE's internals anymore.

Add __fgetcookie(), __fgetpendout() and __fsetfileno() to the private
name space.

Move all the xprintf-related symbols to FBSDprivate_1.0.

Use C comments since we now preprocess these files with CPP.

Now that libc has fcloseall(), remove _cleanup() from the list
of FreeBSD private symbols.

Add fcloseall() to libc. This removes the need to export _cleanup().
Linux also provides an fcloseall() implementation.

Add _cleanup to the list of stdio FBSDprivate symbols. Some
third party applications use this. This will be removed and
replaced by fcloseall() once libc version is bumped.

Add _res to the list of resolv symbols.
