It has only a couple GB of onboard flash storage with no storage
driver in Rockbox. It hasn't seen any meaningful development since
its initial commit, it's not on the build farm, and the bootloader
build is broken by other refactoring.

I feel this is probably unlikely to be called with a NULL pointer
for cachep but being that we are already doing the check why not
guard file_cache_reset as well

Similar to the native port, the hosted port benefits from
adding a -1 dc bias to the PCM data. This prevents almost
all clicking artifacts.

An oversight on my part meant that setting channel balance to
100% L or 100% R would mute both channels - this logic will
prevent that.

A small negative offset seems to silence all
play/pause clicking on the PCM5102A.
Also adding PCM soft muting, and muting the headphone amp
when the headphones are detected as removed. This has been
tested to not cause any unintended side effects on the
line out.
Also confirmed the numerical dB values are (approx.) correct.

This will eventually be used by the ZIP module and other things
that support DEFLATE based streams.

According to backtrace(3) man page, the string returned from
backtrace_symbols() contains the return address so we shouldn't
need to print it ourselves.

Overflow is due to a hidden assumption in create_datetime_filename()
and create_numbered_filename() where buffer must be >= MAX_PATH bytes.

* It had a (read) buffer overflow when dumping the stuff on the back half of the buffer
* a highly questionable code construct was nuked

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

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.

I'm not happy with the proliferation of filter-roll-off options
but I don't have a less ugly solution.

- 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.

This adds code sufficient to extract files to available storage given a
suitable root directory to extract to. It works on an already open zip
handle and also supports chain-loading a secondary callback in the event
that integration into the process is desired.

Do not introduce any change for M:Robe 500 as it uses the two LCD frames
in non-obvious way.
Sansa Connect and Creative ZVM use only single front framebuffer.
Place TTB at DRAM end to minimize memory loss due to alignment.
Reserve as little as possible memory for the LCD frames.
On Sansa Connect this change extends audio buffer by 858 KiB.

This eliminates the dependence on a special struct since we were only
using the modtime anyway. But it no longer fits any known standard APIs
so I have converted it to our own extension instead. This can still be
adapted to existing hosted APIs if the need arises.

This streamlines the boot code a bit and reduces target specific
boilerplate. The clock init hack used by the bootloader has been
"standardized" and works for the main Rockbox binary now, so you
can boot rockbox.bin over USB without special hacks.
