We used 16-bit variables to store the 'character code' everywhere but
this won't let us represent anything beyond U+FFFF.
This patch changes those variables to a custom type that can be 32 or 16
bits depending on the build, and adjusts numerous internal APIs and
datastructures to match. This includes:
* utf8decode() and friends
* font manipulation, caching, rendering, and generation
* on-screen keyboard
* FAT filesystem (parsing and generating utf16 LFNs)
* WIN32 simulator platform code
Note that this patch doesn't _enable_ >16bit unicode support; a followup
patch will turn that on for appropriate targets.
Appears to work on:
* hosted linux, native, linux simulator in both 16/32-bit modes.
Needs testing on:
* windows and macos simulator (16bit+32bit)

Known bugs:
* Native players in 32-bit unicode mode generate mangled filename
entries if they include UTF16 surrogate codepoints. Root cause
is unclear, and may reside in core dircache code.

* Use 16-bit audio output
* More audio tweaks (mute on startup, working volume control)
* Treat the rotary input as a scroll wheel (works now)
To-dos:
* Better global keymap (incorporate touchscreen)
* Turn on plugins and define the approximately eight bajillion keymaps
* Still have some audible pops when we turn on, need to figure out why
* Default Cabbiev2 comes off as rather crappy on this device
...I don't know how much work I will do on this thing, as the limited
number of physical controls (and a lack of a line-out) mean I'd never
want to use this thing myself.

The Echo R1 is a new open-hardware music player design, based
on the STM32H743 microcontroller. Schematics and hardware
documentation for it can be found here:

This is an incomplete port. The bootloader can be loaded using
OpenOCD and it can draw to the LCD using SPI. SDRAM is working
but hasn't been extensively tested.

Cortex-M processors don't have an MMU, but can still have caches
that need software management, so on those platforms we don't want
to include the MMU related functions.
While here, remove an outdated section of a comment referring to
deprecated cache maintenance functions which no longer exist.

This is needed to be able to do updates to the OF due to the fact
that the OF reboots when you select "update firmware".
By default, most OF update images do not update the bootloader,
but it is easy to modify them to do so, and they already contain
a uboot.bin binary.
I tested using the Aigo Recovery from our native bootloader and it
sure seems to work fine.
If we patch the OF update images to load our own native bootloader,
this will be doubly necessary for uninstallation.

The Q1 handles firmware updates by unpacking the firmware image
from the player app, then rebooting into the recovery kernel.
The recovery kernel reflashes the player kernel and rootfs with
the unpacked update files on the SD card.
Booting the recovery kernel directly is therefore not useful to
the vast majority of users; remove the option from the recovery
menu and remove the key combo.

It's now possible to install OF updates on a rockboxed Shanling Q1.
Previously these didn't work because the RB bootloader interrupted
the update process.
Updates will proceed as they normally do on a non-Rockboxed Q1,
except at the end of the update you'll reboot to Rockbox instead
of the OF. This is only a minor inconvienience and doesn't affect
the update process.

There is actually no need to parameterize most commands with row
or column cycles, usually the opcode and row/column address width
are linked. When this is not the case we can use raw SFC commands
or define new macros.

Hold "Play" to boot the OF, or boot it from the recovery menu
by holding "Vol. Up". If you had the hosted port installed on your
player before installing the native port, you'll still have to go
through the hosted bootloader.
A couple notes:
- When booting from the menu, the recovery menu disappears, then
reappears before going into the OF.
- You need to hold the play button for like a half second after the
blue light comes on in order to get into the OF.
The recovery appears to be there, but it doesn't seem to be intended
for end users - it just says "Updater V1.1 - Insert TF Pls". I haven't
tested it beyond seeing that it boots, so I'm going to comment it out
for now.

Bad blocks in a kernel flash partition seem to be handled by skipping
ahead to the next block; this is a common bad block management scheme
for simple software like bootloaders (and is the default method for
reading NAND partitions in u-boot).
Extend the uImage flash reader to skip bad blocks while reading.
