Modified files:

include stdio.h
Added files:
lib/libc/gen fmtcheck.3 fmtcheck.c
Log:
Add fmtcheck(), a function for checking consistency of format string
arguments where the format string is obtained from user data, or
otherwise difficult to verify statically.
Example usage:
printf(fmtcheck(user_format, standard_format), arg1, arg2);
checks the format string user_format for consistency (same number/order/
type of format operators) with standard_format. If they differ,
standard_format is used instead to avoid potential crashes or security
violations.
