f09710a5f7 viacuda: Do shutdown.
Shutdown will enter the debugger or quit depending on the execution mode.
Quit is different from shutdown since it is triggered outside the guest by using the host Quit menu item.

91a8e83f21 main: add more control over logging
Allow the verbosity to be adjusted.

Allow logging to be sent to stderr even when running in interpreter mode.

Allow uptime (time since program start) to be disabled. This makes it
easier to compare logs across successive runs.

50018010c7 Add instruction counters to CPU profiler
Keeps track of instructions (including operands) that are executed,
to see if there are any hotspots that could be optimized or fastpaths
that should be added.

Also adds a mode where CPU profiler data is periodically output, to
make it easier to get at these instruction counts during startup.

fc6a4872d6 Ensure that NVRAM is persisted when exiting the debugger after an abort
The SIGABRT handler is not invoked by the abort() call in the loguru
fatal handler, but either way it's not necessary (it does its own abort).

Switch to explicitly cleaning up the machine object, which as a side
effect in the destructor chain will persist the NVRAM.

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.

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.

35c86ad6bf Clean up #includes
Result of running IWYU (https://include-what-you-use.org/) and
applying most of the suggestions about unncessary includes and
forward declarations.

Was motivated by observing that <thread> was being included in
ppcopcodes.cpp even though it was unused (found while researching
the use of threads), but seems generally good to help with build
times and correctness.

1f7edfdb3b Make Emscripten build not depend on SDL2 or cubeb
While Emscripten has an SDL compabtility layer, it assumes that the
code is executing in the main browser process (and thus has access to
them DOM). The Infinite Mac project runs emulators in a worker thread
(for better performance) and has a custom API for the display, sound,
input, etc. Similarly, it does not need the cross-platform sound support
from cubeb, there there is a sound API as well.

This commit makes SDL (*_sdl.cpp) and cubeb-based (*_cubeb.cpp) code be
skipped when targeting Emscripten, and instead *_js.cpp files are used
instead (this is the cross-platform convention used by Chromium[^1], and
could be extended for other targets).

For hostevents.cpp and soundserver.cpp the entire file was replaced,
whereas for videoctrl.cpp there was enough shared logic that it was
kept, and the platform-specific bits were moved behind a Display class
that can have per-platform implementations. For cases where we need
additional private fields in the platform-specific classes, we use
a PIMPL pattern.

The *_js.cpp files with implementations are not included in this
commit, since they are closely tied to the Infinite Mac project, and
will live in its fork of DingusPPC.

a9fd2453a4 Make assertion messages more visible when we drop into the debugger.
Log output may be sent to a file, ensure that the reason why we're
aborting execution is visible.

5a5ae9fd16 Exit with a non-0 exit code if there are errors
More correct behavior (and makes the Infinite Mac wrapper not close
the emulated Mac, which it does when it thinks there was a graceful
shutdown).
