unbreak ieeefp emulation code wrt converting double to unsigned
long ints for alpha. we've got only one instruction (cvttq) to
convert double-t to quadword, and float64_to_int64 did not take
into account the unsigned conversions
therefore, overflow always occured, and half of the unsigned range
(LONG_MAX .. ULONG_MAX) was broken
introduce roundAndPackInt64NoOverflow and float64_to_int64_no_overflow
for softfloat, that works with unsigned integers as well. note
that this will return zero for nan/inf/oflow/uflow, raising exception
flag
perl is happy now
looked over by miod@
tested by naddy@, and by me on nick@'s alpha

First pass at removing clauses 3 and 4 from NetBSD licenses.
Not sure what's more surprising: how long it took for NetBSD to
catch up to the rest of the BSDs (including UCB), or the amount of
code that NetBSD has claimed for itself without attributing to the
actual authors.

IEEE 754 floating point completion code, and implementation of the
FP_C (Floating Point Control Quadword).
From ross@NetBSD. Added a way to disable it with option NO_IEEE,
which appears on the ramdisks to save space. This affects only
programs compiled with -mieee, and what it essentially does is
enabling infinities and NaNs, instead of generating SIGFPE on
division by zero, overflow, etc.
ok art, deraadt
