fenv(3) support for hppa
--
use unsigned over uint32_t so that this file works without stdint.h
being included before hand.
fixes mknative-gcc problems, and likely others.
--
Properly separate fenv.h and ieeefp.h by moving all fenv defines
over to the former.
Now that they are decoupled, make rounding modes match the hardware bits.
--
Simplify, now that rounding mode defines match the hardware bits.
