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.

7b4d513e22 videoctrl: Add change resolution support.
PDM defaults to 640x480.
If you set --mon_id to MacRGB12in then it would draw 512x384 inside a 640x480 window.
If you set --mon_id to Multiscan20in then it would try to draw 832x624 inside a 640x480 window and crash.
If you set the Monitors control panel to switch multiscan display from 640x480 to 832x624 and  restart then it would crash.
Now it will correctly change the window size every time the mode changes.

8 bits at Offset 2 is PLL_DATA. If we don't modify PLL_DATA, then insert the current value of PLL_DATA into the value that will be read from ATI_CLOCK_CNTL.

214c61669a videoctrl: Add pixel_format.
pixel_format is different than pixel_depth.
pixel_format depends on the GPU. A GPU might have multiple formats for the same depth.
We store this in videoctrl so that we can detect changes in pixel_format like we do for pixel_depth and active_width and active_height.

fb0396923f Fix dma STORE_QUAD and LOAD_QUAD.
When fetching DMA command, make sure to convert little endian fields to host endianness (i.e. don't use memcpy).
When fetching DMA command, return the host address of the DMA command for LOAD_QUAD. Maybe this address should be cached whenever this->cmdptr changes?
When fetching DMA command, return whether the DMA command is writable.
For LOAD_QUAD, pass the address of the DMA command to xfer_quad.
Always log unexpected DMA command values.
Write full 32-bit value for LOAD_QUAD.
Write reqCount to resCount.

54bda0ea95 pci: Change pci_conv_rd_data unaligned.
pci_conv_rd_data can be used to handle unaligned or 64-bit accesses in mmio regions if it's modified to include the next 32-bit value.
For pci config accesses, grackle repeats the 32-bit value. bandit uses a seemingly random number for the next 32-bit value, but we'll make it work like grackle.
