a941836a4d Add support for specifying properties of dynamically-registered devices via the command line
The previous approach of traversing the machine and its device tree
at startup to register CLI11 options was not working for dynamically
registered devices like PCI cards. This meant that options like
gfxmem_size or mon_id from the video cards could not be set.

Switch to instead registering in MachineFactory a hook function that
provides CLI flag values. We can call it when registering any property,
whether at startup or dynamically.

e1849a2bfd dbdma: Schedule interpret_cmd.
Have the entire dbdma program executed by scheduling each iteration in the CPU loop.
This is done only for devices that use the dbdma program to drive data input/output (has_data_callbacks) rather than have the device drive the dbdma program.

e7eb1c8a66 Fix PCI interrupts and add devices.
- Use interrupt source instead of IRQ ID in the IrqMap.
- Add a get_interrupt_controller method to mirror the set_interrupt_controller method.
- Have PCI hosts use pcihost_device_postinit to add PCI devices. This was moved from bandit's device_postinit and allows for duplicate devices by appending the slot to the registered device name.
- Fix interrupts of Pippin.

Fix interrupts of cmd646
- Make it work like other PCI devices.
- IntDetails is built into the pcibase base class.
- IntDetails is initialized by calling pci_interrupt.
- pci_interrupt checks the "enable interrupts" flag before doing an interrupt.

Merge pull request #120 from mihaip/upstream-deterministic
Add a deterministic execution mode

f65f9b9845 Add a deterministic execution mode
Adds support for a --deterministic command-line option that makes
repeated runs the same:
- Keyboard and mouse input is ignored
- The sound server does a periodic pull from the DMA channel (so that
  it gets drained), but only does so via a periodic timer (instead of
  being driven by a cubeb callback, which could arrive at different
  times)
- Disk image writes are disabled (reads of a modified area still
  work via an in-memory copy)
- NVRAM writes are disabled
- The current time that ViaCuda initializes the guest OS is always the
  same.

This makes execution exactly the same each time, which should
make debugging of more subtle issues easier.

To validate that the deterministic mode is working, I've added a
periodic log of the current "time" (measured in cycle count), PC
and opcode. When comparing two runs with --log-no-uptime, the generated
log files are identical.

27d389c36a debugger: Erase prompt when repeating command.
Enterring a blank command continues the disassembly or stepping for one instruction. Erasing the prompt saves one line in the console so the disassembly doesn't appear double spaced. I don't know if the terminal control sequence works in Windows.

c6116fcc88 grandcentral: pass Curio DREQ state to its DMA channel.
Bit 5 of the channel status register of the SCSI0 DMA channel
reflects the DREQ signal from Curio.
The old SCSI API still used in some Macintosh applications
- most notably HD SC Setup and Drive Setup - relies on this API
and that signal to be implemented.

34e0ba84f1 Add AppleJack controller support, based on AdbMouse
All AppleJack controllers start in mouse emulation mode, behaving exactly like
ADB mice. Only upon receiving a Listen command on register 3 with handler ID
0x46 does the AppleJack switch protocols, albeit such a change consisting merely
of expanding register 0's buffer size to 4 bytes. In this state, the first 2
bytes remain defined as they are for an ADB mouse; the additional 16 bits carry
the respective states of each of the AppleJack controller's remaining 11 buttons
out of a possible supported 16.

For backward compatibility, honor both mouse clicks and shoulder button presses
on the host when considering the state of the emulated trigger buttons.

d23f21b391 sdl: handle gamepad events
Add new GamepadButton enum with bits corresponding to AppleJack button bits.
Both the AppleJack controller and the SDL GameController coincidentally define
one d-pad, two shoulder buttons, four face buttons, and three system buttons.
This makes mapping modern game controllers to the AppleJack straightforward.
