Merge CT_CCL and CT_STRING handling before we add %m.
Also fix an accidental scanf/wscanf difference.
Add currently-disabled tests for questionable behavior noticed during
code review that isn't a regression, but should be fixed later.

Strictly, POSIX says "If a '-' is in the scanlist and is not the first
wide character, nor the second where the first wide character is a '^',
nor the last wide character, the behavior is implementation-defined",
but it seems unreasonable for swscanf to interpret `a-c` differently
from sscanf. Make ours behave the same as each other by making swscanf
work the same as sscanf.

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.)

The parsefloat routines -- which let us pass NaNs and infinities on to
strto(f|d|ld) -- come from NetBSD.
Also fix LP64's strtold to return a NaN, and fix all the architectures
to return quiet NaNs.
Also fix wcstof/wcstod/wcstold to use parsefloat so they support hex
floats.
Lots of new tests.
