Gabriel F. T. Gomes 726d48ec96 Use read_int in vfscanf
The function read_int, from printf-parse.h, parses an integer from a string
while avoiding overflows.  It is used by other functions, such as vfprintf,
to avoid undefined behavior.

The function vfscanf (_IO_vfwscanf) parses an integer from the format
string, and can use read_int.
