High-frequency files increasingly use a block size of over 4608B, which
means we need larger buffers to decode them. However, larger buffers no
longer fit in IRAM on less-capable devices, hurting performance for
"normal" file playback.
On our slowest devices (M68K and PP-based devices), this is not worth
the tradeoff as they will likely not have enough CPU oomph to decode and
downmix these files in realtime.
S5L87xx-based devices have the raw performance to do this, so we decided
to err on the side of wider file compatibility at the cost of some
performance.
All other devices are unaffected.

By switching them from (const void* volatile*) to (void* volatile*)
The 'const' bit was causing GCC>4 to optimize away writes to those
addresses when compiled with -Os, badly breaking the interrupt handler.

Clarifies presumably intentional fall-through for
PF_TRACKLIST and fixes unwanted behavior of
PF_TRACKLIST while scrolling, which may have
started playback instead of showing the track list.

When you're using a "large" screen device, and the message doesn't need
to scroll, parts of the previous mesage are left behind.
Work around this by explicitly clearing the messgage with a loooong
blank string.

It is particularly stack-heavy (>1.25K, >2.25K with 32-bit unicode)
Its only caller was font_load_ex() but that can be called recursively
which _really_ blew up the stack.

cRSID natively renders its output as a 16bit mono stream. There's no
reason to not use it as-is, and save a bunch of CPU cycles in the
process.

By default STMP3700 launches from negative edge for capture on positive edge.
If we leave DPL (bit 13 of reg 0x13) to 0, it will be captured on falling edge,
resulting in a potentially undefined behavior. Some make sure LCD captures on
rising edge. Alternatively we could change the dotclk polarity in VDCTRL0.

We've received multiple reports from users of 6th gen iPods where we
fail to find any mountable partition. A user was able to supply an MBR
dump, which showed that the "type" listed for parition 0 was set to 0x00
(ie "unused"), leading us to (correctly) completely ignore that entry.
However, it looks like the stock firmware ignores the type and
unconditionally uses the first entry even if it's nominally "invalid"
So, to deal with this, always try to mount partition 0 if it is not one
of the two "extended partition table" types. If that speculative mount
succeeds, we now treat it as type 0x0c (Fat32 w/LBA) internally.
Note that this will not allow the partition to be mountable over USB, as
the MBR is still incorrect, leading the host OS to ignore the partition.
Further complicating things, the stock Apple firmware always constructs
a fake MBR to hand to the host!
To prevent user confusion with these devices, we may consider faking the
MBR too; alternatively we could correct the MBR and write it back to
disk, perhaps via a debug menu option.

musl doesn't unload shared objects when we dlclose() the handle. This means
it also never re-initializes them if we try to re-launch.
This means that global state is persisted across invocations instead of
being wiped. Until we come up with a proper workaround we can apply
globally, have the textviewer clean up the important global state when
it exits.

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
* on-screen keyboard
* font manipulation, caching, rendering, and generation
* VFAT code parses and generates utf16 dirents
* WIN32 simulator reads and writes utf16 filenames
Note that this patch doesn't _enable_ >16bit unicode support; a followup
patch will turn that on for appropriate targets.
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.
Needs testing on:
* windows simulator (16bit+32bit)
