Clean up fpu_extern.h; only a function public to external is fpu_emulate().

Other functions are private to fpu_*.c and therefore live in fpu_emu.h.

Also, drop needless forward struct declarations.

NFC.

static-fy fpu_execute().

static-fy fpu_[ixsd]tof(). NFC.

Make fpu_explode() and fpu_implode() take uint64_t and uint64_t *,
instead of register number, respectively. NFC.

static-fy fpu_fto[ixsd](). NFC.

Fix fcti{w,d}{,z}.

- Treat 64-bit integer correctly for fctid{,z}.
- Respect round mode specified by FPSCR[RN].

XXX
- Set FPSCR[FR] and [FI] appropriately.
- Also set FPSCR[FPRF]?
- fctid{,z} traps on powerpc32 (confirmed on 603e and G4).

u_int64_t --> uint64_t. No binary changes.

Add support for PPC FP emulation to BookE.
Pass a ksiginfo_t to fpu_emulation so it can give more detailed
info on signals.

Fix the sync with head I botched.

Remove (the now non-compiling) support for 128bit FP emulation, which
isn't needed for PowerPC anyway.

Add a port to IBM's PPC405GP Reference Board (the "walnut")
by Eduardo Horvath and Simon Burge of Wasabi Systems.

IBM 4xx series CPU features:
 - New pmap and revised trap handler.
 - Support on-chip timers, PCI controller, UARTs
 - Framework for on-chip ethernet and watchdog timer.
General PowerPC features:
 - Add in-kernel PPC floating point emulation
 - New in{,4}_cksum that is between 1.5 and 5 times faster than the
   old version depending on CPU type.
General changes:
 - Kernel support for generic dbsym-style symbols.
