* editfns.c (Fformat): Fix several integer overflow problems.
For example, without this change, (format "%2147483648d" 1) dumps
core on x86-64 GNU/Linux. Use EMACS_INT, not size_t, for sizes,
since we prefer using signed values, and EMACS_INT will be big
enough soon, even on 32-bit hosts. Also, prefer EMACS_INT to int
for sizes. Don't assume that pI is either "l" or ""; it might be
"ll" or "I64". Check for width and precision greater than
INT_MAX, as this can make sprintf go kaflooey. (Bug#8668)
