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)

characters less than the first diacritic in the symbol table (0x300)
return false after checking the MRU table
we gain some performance by eliding the function call all together if less than first diacritic

a new slot gets added but it is set to 0 and an entry gets discarded
instead set it to the last entry read

REMOVED FROM ALL NATIVE BOOTLOADERS:
finish removing the text scrolling
pare down printf to a minimal subset (%c %s %l %d %u and %x(%p))
remove diacritic and rtl language support

is_diacritic is used for pretty much all of the text display sizing
Timing here matters, so important it uses a
priority buffer in order to cut down on searching the database.
This patch is verified functionally equlivalent but
saves 80 bytes and is ~20% faster for the clip+ I tested it on
Several things were done:
Optimizing the copy loop for the priority buffer
Globbing some operations together
but the main one has to do with the database structure its self
--
Rather than a bit packed struct it combines the lower 8 bytes into
one value [info] and uses flags to access the values instead

- Move diacritic.c to firmware/common
