invalid format strings invoke undefined behavior, so this is not a
conformance issue, but it's nicer for scanf to report the error safely
instead of calling free on a potentially-uninitialized pointer or a
pointer to memory belonging to the caller.

check in configure to be polite (failing early if we're going to fail)
and in vfprintf.c since that is the point at which a mismatching type
would be extremely dangerous.

for conversion specifiers, alloc is always set when the specifier is
parsed. however, if scanf stops due to mismatching literal text,
either an uninitialized (if no conversions have been performed yet) or
stale (from the previous conversion) of the flag will be used,
possibly causing an invalid pointer to be passed to free when the
function returns.

this seems to have been a regression from the refactoring which added
the 'm' modifier.

this commit only covers the byte-based scanf-family functions. the
wide functions still lack support for the 'm' modifier.

this brings the wide version of the code into alignment with the
byte-based version, in preparation for adding support for the m
(malloc) modifier.
