Modified files:
lib/libc/stdio fseek.3 fseek.c stdio.c
Log:
1) Disallow negative seek as POSIX require for fseek{o} (but not for lseek):
"[EINVAL] ... The resulting file-position indicator would be set to a
negative value."
Moreover, in real life negative seek in stdio cause EOF indicator cleared
and not set again forever even if EOF returned.
2) Catch few possible off_t overflows.
