This commit moves all first-party code developed for this project from lib/
to shared/, so that lib/ now only contains third-party code.
The following directories are moved as-is from lib to shared:
lib/libc -> shared/libc
lib/memzip -> shared/memzip
lib/netutils -> shared/netutils
lib/timeutils -> shared/timeutils
lib/upytesthelper -> shared/upytesthelper
All files in lib/embed/ have been moved to shared/libc/.
lib/mp-readline has been moved to shared/readline.
lib/utils has been moved to shared/runtime, with the exception of
lib/utils/printf.c which has been moved to shared/libc/printf.c.

I was puzzled by why the dictionary words were sorted by length.
It was because TextSplitter sorted its parameter, instead of a copy.
This doesn't affect encoding size, but does affect the encoding NUMBER
of the found words. We'll deliberately restore sorting by length next,
for other reasons, but not by spooky action.
Try to accurately measure the costs of including a word in the dictionary
vs the gains from using it in messages.
This saves about 160 bytes on trinket_m0 ja, the fullest translation
for that board. Other translations on the same board all have savings,
ranging from 24 to 228 bytes.

As the CircuitPython grows, it may at some point no longer be possible
to squeeze it on some of the flash-less SAMD21 boards, so it would be
good to have the option of shrinking the filesystem size on per-board
basis. This change allows to define CIRCUITPY_INTERNAL_FLASH_FILESYSTEM_SIZE
inside the board's mpconfigborard.h file.
Changes are:
- update axTLS from 2.1.3 to 2.1.5
- os_port.h is now provided by the user of the library
- PLATFORM_RNG_U8 can be defined for get_random
- fix -fsanitize=undefined diagnostics

1. Check for correct error values from dma_claim_unused_channel.
2. Introduce a .stereo flag for simplicity.
3. Clarify PWM carrier frequency choice.
4. Start introducing quiescent audio value. Still need to ramp up/down.
5. Redo audio stop logic a bit.
6. Fix (unrelated) displayio dependency things.
There is still an interference problem between other DMA users and audio. Still debugging this.
To reduce the number of calls to mp_hal_stdout_tx_strn and improve the
overall throughput of printing data. This implementation is taken from
ports/stm32/mphalport.c.
