vsprintf: fix bug in negative value printing
Sitsofe Wheeler found and bisected that while unifying the vsprintf format decoding in: fef20d9: vsprintf: unify the format decoding layer for its 3 users The sign flag has been dropped out in favour of precise types (ie: LONG/ULONG). But the format helper number() still needs this flag to keep track of the signedness unless it will consider all numbers as unsigned. Also add an explicit cast to int (for %d) while parsing with va_arg() to ensure the highest bit is well extended on the 64 bits number that hosts the value in case of negative values.
