c5ac862cef debugger: Add list of input and output registers.
So the debugger can show them during stepping.
The fmt_* functions now take a PPCDisasmContext instead of just the ctx->instr_str so that they can alter the context.
Some fmt_* functions have an alternate (e.g. fmt_twoop_in for fmt_twoop) to indicate a difference in input/output registers.
The mtsrin and mfsrin instructions use a register to indicate which sr register to use.
The string instructions may affect multiple registers but only the first is included in the list.
Removed some extra blank lines.

Fixes:
lscbx: Add r0 check.
mftb: Do simplified if the spr is illegal. Maybe should do illegal opcode instead?

57e6e90002 Add support for the CUDA_RESTART_SYSTEM command
There are cases where when it's necessary (e.g. given uninitialized NVRAM,
the Beige G3 with the 10.2 install CD inserted will update the boot
device and restart to boot from it).

Restart support was done by wrapping the ppc_exec function in a loop and
checking for a restart power off reason. We also need to disconnect all
event listeners, since they will be recreated when the machine is
re-initialized.

67bd47f11f ppcopcodes: Fixes for bcctr(l)?.
Add MPC601 variants. Variants that decrement and test the ctr are invalid bon't don't appear to trigger an exception. The manual says MPC601 can decrement the counter. Other CPUs do not decrement the counter but will branch based on the value.

177098c957 debugger: Fix interrupt signal.
Typing Control-C in Terminal app causes an interrupt signal that should enter the DPPC debugger but this only worked once since the signal handler never returned. Even if the signal handler reenabled the signal somehow, it calls enter_debugger recursively which is strange since the earlier calls to enter_debugger would never return.

Now the signal handler just sets a flag (power_on) which can be used to exit any loop (emulator loops, stepping loops, disassembly loops, dumping loops).

Main always calls enter_debugger now which calls the ppc_exec loop. The power_on flag will exit the ppc_exec loop to return to the debugger. Recursion of enter_debugger is eliminated except for calls to loguru's ABORT_F.

An enum power_off_reason is used to indicate why the power_on flag is set to false and to determine what happens next.
