o Add SIM_SIGFPE to sim-signals
...
o Start SIM_SIG* at 64 so that the use of host signal numbers can be
detected and reported.
o Update MIPS simulator to use sim-signal.

Replace global IPC with function argument cia or current instruction
...
address.
Pass cia into calls to sim_engine_stop so that breakpoints et.al. work.

IGEN likes to cache the current instruction address (CIA). Change the
...
MIPS simulator so that correctly writes the value of CIA back int PC
(the global previously used) when the simulation halts.
Fix implementation of DELAY_SLOT and NULLIFY_NEXT_INSTRUCTION macros.

Rewrite the MIPS simulator's memory model so that it uses the generic
...
common/sim-core.
Add support for 3, 5, 6, 7 byte transfers to sim core.

Delete -l and -n options, didn't do anything.
...
Rename option trace to dinero-trace & dinero-file - -t clashed with
common options.
Enable common trace options.

Rewrite sim_monitor (implements read, write, open, et.al. system
...
calls) and sim_open so that they uses the virtual memory data transfer
functions sim_read & sim_write. This eliminates all code (other than
in load_memory & store_memory) that makes assumptions about the
implementation of the underlying memory model.

Add function to fetch 32bit instructions
...
When address translation of insn fetch fails raise exception immediatly.
Use address_word as type of all address variables (instead of unsigned64),
the former is configured as either 32 or 64 bit type.
Always compile fpu code (no #if has fpu)
