only alloc enough space for the path instead of a fixed buffer
round up the path buffer size to slightly more thna the longest
common path length to reduce reallocations

Naming your allocations is more of a debugging feature; it's a
bad idea to abuse this feature for storing some random string.
The font code does exactly that to remember the path used to
load a font, and it's the only code that uses buflib names in
this way.
Store the path inside the font allocation instead as a regular
char array. For simplicity it's MAX_PATH sized, so this'll use
a bit more memory than the buflib name method, maybe 1-2 KiB if
a few fonts are loaded.

replace applicable calls to strlcpy with calls to strmemccpy
which null terminates on truncation
in theory the strmemccpy calls should be slightly faster since they
don't traverse the rest of the source string on truncation
but I seriously doubt there is too much of that going on in the code base

splits on spaces also considers \r\n\f\v\t as mandatory breaks
I'm still working on the strptokspn function
my goal is to use it directly rather than storing the matched char
and modifying the source string with \0 in order to tokenize the output

Several places in the codebase implemented an ad-hoc form of pinning;
they can be converted to use buflib pinning instead.

The Q and K have a slightly different case, but the hardware under the
shell is completely identical.
These models are rebadged versions:
* Hifiwalker H2 (== Q)
* AGPTek H3 (== K)
* Surfans F20 (== K)
Other notes:
* Significant improvements in the shared Hiby-platform launcher/loader
* SD card can theoretically be hot-swapped now
* Support external USB mass storage!
* Some consolidation of Hiby-platform targets
* Some consolidation of plugin keymaps
Todo/known issues:
* Keymaps need to be gone over properly
* Convert to HAVE_SCROLLWHEEL?

NOTES:
- bootloader makefile convert an extra font to be installed alongside the bootloader
since sysfont is way too small
- the toolsicon bitmap comes from the Oxygen iconset
- touchscreen driver is untested
TODO:
- implement audio routing driver (pcm is handled by pcm-alsa)
- fix playback: it crashes on illegal instruction in DEBUG builds
- find out why the browser starts at / instead of /contents
- implement radio support
- implement return to OF for usb handling
- calibrate battery curve (NB: of can report a battery level on a 0-5 scale but
probabl don't want to use that ?)
- implement simulator build (we need a nice image of the player)
- figure out if we can detect jack removal
POTENTIAL TODOS:
- try to build a usb serial gadget and gdbserver

The builtin sysfont does not have an associated buflib_alloc_data
(because it's builtin right?). font_get_{width,bits} accessed a field of
it for all fonts which crashed on some systems but not on mine.
Solution: Move this field to struct font directly.
The cache size calculated was also busted.
Fixes FS#12944 and most likely FS#12938.

The font engine can now perform cache lookups even if the font file is
closed, if the font was disabled with the new font_disable_all() function.
It is highly probable that the lookup succeeds but in the cache-miss case
a blank, full-width glyph will be returned.

Buffers are not allocated and thread is not created until the first
call where voice is required.
Adds a different callback (sync_callback) to buflib so that other
sorts of synchonization are possible, such as briefly locking-out the
PCM callback for a buffer move. It's sort of a messy addition but it
is needed so voice decoding won't have to be stopped when its buffer
is moved.

This fixes errornous pointer addition (+ on a short*), which crashed in some situation.
Fixes FS#12317 and should hopefully get the clips booting again.
Thanks to Jonathan Gordon for spotting the bad pointer arithmetic.

This enables Rockbox to render anti-aliased fonts using an alpha blending method.
The input font bitmaps are 4bit, i.e. 4x larger, but the metadata size stays the same.
A tool, convttf, for converting ttf fonts directly to the Rockbox fnt format is provided.
It has a useful help output, but the parameter that works best is -c1 or -c2 (2 for larger font sizes).
