Modified Files:
        src/sys/kern: kern_event.c

Log Message:
>From tedu at openbsd:

kevent validates that ident is a valid fd by getting the file. one sad
quirk: uint64 to int32 truncation can lead to false positives, and then
later in the array sizing code, very big mallocs panic the kernel.
add a check that the ident isn't larger than INT_MAX in the fd case.
