There's TLS space used for unknown errno values, and a call to printf
shouldn't clobber that. No-one will ever hit this in real life, but
since it's easily fixed...

libc had some -Wimplicit-fallthrough warnings. They all seem to be
benign. We're trying to enable this flag globally, so we need to
annotate these breaks here.

We've ignored %n for a long time, but that's dangerous too because it
makes it unclear whether the corresponding pointer argument should be
supplied or not.
Remove the ambiguity by just rejecting %n outright.

Just trivial use of macros.
The %s/%ls case in __find_arguments was backwards in the wide copy of
the code, but not problematically so because all pointers are the same
size anyway.

Android is UTF-8. Don't make everyone pay to convert UTF-8 to ASCII just
so we can recognize '%'. With UTF-8 we can just strchr forwards.

Add missing __find_arguments error checking to the wide variant to match
the regular one.
Also replace various char/wchar_t differences with the macro.

Fix the 'j' (intmax_t/uintmax_t) length qualifier in the wide
variant. (With new tests that fail without this fix.)
Fix a typo in the wide support for intmax_t*, which isn't testable because
%n is disabled on Android (and will be removed in a later cleanup pass).
Also move the public vfprintf/vfwprint functions into stdio.cpp.

This patch switches to C++ (in anticipation of needing it later), removes
a little duplication (via a macro for now), and ensures uniform support
for %C/%lc and %S/%ls between regular and wide (with new tests).
Since it's so hard to debug problems in printf (as the time I've wasted
already today will testify), that's all I want to do in this change. The
other 500 lines of diff can wait...
(Also merge "floatio.h" into "local.h" now all the users are in forked
code.)
