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.

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.

fb0396923f Fix dma STORE_QUAD and LOAD_QUAD.

When fetching DMA command, return whether the DMA command is writable.
For LOAD_QUAD, pass the address of the DMA command to xfer_quad.

d08b486db0 Fix keyboard events occasionally being dropped
AdbKeyboard would copy the event into its own fields and set the

However, if a subsequent event was received before ADB polling, the
previous event would be overwritten and lost.

Fix this by maintaining a queue of events, so that we can return
everything since the last poll.

Besides generating KeyboardEvents in the SDL event handler and
returning the key state in the register 0 reads of the AdbKeyboard
device, we also needed to generalize the ADB bus polling a bit. We now
check all devices that have the service request bit set, instead of
hardcoding the mouse.

The SDL key event -> ADB raw key code mapping is based on BasiliskII/
SheepShaver's, but cleaned up a bit.

e011d86742 amic: don't reset cur_buf_pos if we've drained the DMA buffer
Otherwise if pull_data is called again, it will think that it still
has data available in the buffer (rem_len will be non-zero) and
random data at the buffer location will be returned.

This manifested itself as noise being played back in the JS
implementation of the SoundServer. The cubeb implementation was not
affected because it stops polling once it's told it has no more
data in the buffer. Both approaches are valid (the JS version pads
data with silence), and the DMA buffer should support both.

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.

637844269f atapicdrom: Implement sector areas for Read CD.
The disk cache is unchanged. data_ptr continues to be only used for the user data sector area for each block. The other sector areas (synch, header, etc.) are filled in while reading.

has_data and get_data exist as a way to bypass data_ptr for parts of the transfer outside the user data sector area of each block. The default behaviour is defined in atabasedevice and is overridden by atapicdrom for the Read CD command. atapicdrom has a flag doing_sector_areas to control the behavior of the get_data method. When the flag is true, the sector_areas, current_block, and current_block_byte are used for selecting the correct data from one of the sector areas. The Read CD command initializes those variables. xfer_cnt remains the total number of bytes to be transferred and is now not necessarily the same as the number of disk image blocks read into the disk cache.

lba_to_msf is used to fill in the header. The values was not verified using a real CD.

Mac OS X just cares about the Mode in the header. For now, only the synch and header and user data areas are filled in. The other areas read as all zeros.

439509b408 Fix New World NVRAM limits calculations.
It was possible to corrupt New World nvram using dingusppc setenv command.

- setenv must call get_config_vars to set data_length so that it can calculate free space.
- data_length represents the number of bytes taken by nvram variables including the terminating null for the value (name, '=', value, '\0'). Previously, it did not include the terminating null.
- The list of variables and values ends at a '\0' or at pos == 4096 bytes. Previously, data_length wouldn't get set if pos >= 4096.
- Allow setenv to create new nvram variables.
- Since data_length now represents the total number of used bytes, free_space now represents the actual free space, so use > free_space (instead of >= free_space) to determine insufficient space.
- While parsing nvram variable name, do not read beyond 4096 bytes.
- Use a different error message for each problem that can occur while parsing nvram variable name.
