ARMv7-M has hardware division, so it doesn't require __div0
or any support functions for 32-bit division.

the YPR1 apparently can do voltage or percent measure
I'm pretty sure its missing logic for disksafe and shutdown,
perhaps the device takes care of it for you?
hopefully someone with the device notices the issue
(perhaps due to a older battery needing capacity tweaked)

when battery_bench is run
exports a file in the rockbox directory called 'battery_levels.default'
if the user wants their own levels they can rename the file battery_levels.cfg
and it will be loaded at boot

GCC 9.5 issues a -Wmisleading-indentation warning due to an extra
semicolon at the end of the while loop. It does seem unintentional
since the loop is a busy wait, so remove the semicolon.

The "charging" status is apparently "charging needed" as it
is asserted even when power is not being supplied. So first check
to see if USB is connected, and if so, then check the "charging" status.

On PATA, we'd cap our transers at UDMA2 if the device reported that an
80 pin cable wasn't detected, but SATA devices do not perform this test.
So alter the check to only apply on PATA devices, so that SATA devices
can run at full UDMA speeds.

On these older iPods, power was not being shut down completely, which led to a backfeed situation leading to decreased battery life and some stability issues.
This was particuarly apparent when using SD card adapters that do not
respect the ATA power management commands (ie all of them), as they never enter a low-power state on their own.
With this change, there are reports of battery life exceeding 20 hours of continuous playback (~30% increase with CF cards, 3x improvement with SD cards) and appears to resolve intermittent wakeup stability issues with SD adapters.

Use AXP2101's egauge battery percent level if available (hw4 units).
If not available (_battery_level() will return -1 on hw1-hw3 units),
fall back to voltage battery level.
Also fix logic in axp2101_battery_status()

If I'm interpreting the git history correctly,
the config file for Zen Vision was at some point
inadvertently replaced with one for the
Zen Vision:M.
This deletes the currently unused creativezv.h,
and moves its contents into zenvision.h.
The config files appear to be identical except for
CREATIVE_ZV vs CREATIVE_ZVM define, different
keypads (CREATIVEZVM_PAD vs CREATIVEZV_PAD) and
BOOTFILE_EXT (zv vs zvm), a different model name
and number, as well as different LCD dimensions
and DPI.
The buttonmap still seems to require adjustment.

Improve ADC behavior, add correct conversion
for die temperature, add readout of EGauge to debug screen.
Add delay to give ADC time to get a good reading. Initial reading
may still be 1-3% optimistic, which is probably ok.
EGauge appears to be pretty good, but no great need to convert
to using it either.

This enables smooth resizing of the window using a
fixed aspect ratio, instead of snapping into the
correct aspect ratio only when the resize operation
has finished, by using an SDL event filter that gets
events delivered during the resize operation
(whereas SDL_PollEvent blocks until done on macOS).

On Windows, we need to prevent the event thread

SDL 2 lets us take advantage of a fixed logical resolution,
where the renderer scales content up or down automatically.
Relative mouse motion is also affected by renderer scaling
by default (see SDL_HINT_MOUSE_RELATIVE_SCALING).
If window zoom has been enabled from the command line,
set scaling quality to "nearest pixel sampling" instead
of "best" to allow pixel peeping.

Tested on Linux, MacOS, and Windows.
On MacOS and Windows, we constrain the window's aspect
ratio by adjusting the size when responding to resize
events.
On Linux, I've not found a way to do so, that doesn't
result in fairly stuttery behavior and weird jumpy
behavior of the resize handle, possibly depending
on your window manager. So, black bars are displayed
around the content.
Maybe someone, at some point, finds a way.
(SDL3 seems to have SDL_SetWindowAspectRatio)
When the window is in fullscreen, black bars are
display necessarily, of course, on all systems,
unless the player GUI has exactly the same aspect
ratio as the screen...
