This adds an adapted version of the adler32 algorithm from tinf/zlib
which will be necessary to support ZLIB deflate streams in the future.

The nightly manual builds previously only included targets that were
marked as "stable" -- The M3K and Q1 are not because they lack rbutil
integration, but we would like to provide the manual builds regardless.

Includes installation instructions and a description of Rockbox's
limitations versus the original firmware. Some things are still
missing, notably screenshots for the Q1. The M3K image also needs
to be updated to include the 'select' button.

The funny thing is that the memset() for the field in question was
redundant, as the overall inquiry structure was memset(0) already.

Since battery_bench is a TSR (terminate & stay resident) plugin it
cannot allocate the plugin buffer -- various parts of the Rockbox
core make use of it as temporary storage space. The buffer was used
for stack space so this generated false 'Stkov' panics when one of
those in-core users overwrote the buffer.
The default stack size of 1kb is a bit small, so use 4x the default
size to be on the safe side.
This also fixes a minor issue where trying to view OS stack usage
while battery_bench was running would cause audio dropouts, due to
scanning the possibly huge stack with IRQs disabled.

Since this is a TSR plugin, it is not safe to use the plugin buffer.
Convert to using static buffers instead.

- Make the argument const since it's not actually mutated
- Actually return the size of the buffer used since this is what it
was supposed to do (although no existing callers cared anyway)

The code is explcitly relying on twos complement numerical represntation
so this just shuts up the compiler and static analysis warnings.

What works:
- LCD: 16-bit RGB565
- all buttons, including scrollwheel
- SD Card
- Battery level and charging/not charging status
- USB
- audio
- sample rate switching
- HP / LO detect, with "safe" fixed LO volume -
LO volume will only be put to user-defined max volume
if headphones are not present.
- rtc
- Plugins build, tried a couple and they seem OK
- Bootloader, installable to nand via usbboot
What doesn't work:
- Dual Boot
- power on/off has intermittent, low volume audio click
(sometimes it's completely silent, sometimes there's
a click)
- Audio uses 16-bit volume scaling, so clicking/popping
is pretty bad at lower volumes - need 32 bit volume
scaling, 24 bit I2S data
- USB HID keys not yet defined
- no jztool support
Unknowns:
- Stereo Switch pins: Direction select, AC_DC
(probably not even hooked up)
- What is the actual purpose of the Stereo Swtich?
- How does the bluetooth module connect?
"Someday" stuff:
- get LCD working at higher bit depth
- Bluetooth

This relies on a macro, CRC32R_FAST, to select which version to
compile with. In tests the fast version is 2x faster at the expense
of requiring 960 more bytes for the lookup table. For now the default
is the space optimized version but in the future I would like to enable
this for ports where we can afford the extra storage and/or memory
requirements.

- Audio playback works
- Touchscreen and buttons work
- Bootloader works and is capable of dual boot
- Plugins are working
- Cabbiev2 theme has been ported
- Stable for general usage
Thanks to Marc Aarts for porting Cabbiev2 and plugin bitmaps.
There's a few minor known issues:
- Bootloader must be installed manually using 'usbboot' as there is
no support in jztool yet.
- Keymaps may be lacking, need further testing and feedback.
- Some plugins may not be fully adapted to the screen size and could
benefit from further tweaking.
- LCD shows abnormal effects under some circumstances: for example,
after viewing a mostly black screen an afterimage appears briefly
when going back to a brightly-lit screen. Sudden power-off without
proper shutdown of the backlight causes a "dissolving" effect.
- CW2015 battery reporting driver is buggy, and disabled for now.
Battery reporting is currently voltage-based using the AXP192.

Debounce logic now handles both removal and insertion and verifies
the detection is stable for 100ms before taking any action.
This solves the bootloader "file not found" issue on the Shanling Q1.
It seems a false removal event was generated, causing the filesystem
to be automatically unmounted. Probably this is due to some transient
noise at boot. Delays didn't solve the problem, probably because the
bogus hotplug event was queued, and normal mdelay() would simply delay
event delivery.
