* Add fast_timer_t that is 16-bit or 32-bit based on architecture
A 16-bit timer will overflow sooner but be faster to compare on AVR.
* Avoid 8-bit timer overflows in debounce algorithms
Count down remaining elapsed time instead of trying to do 8-bit timer
comparisons.
Add a "none" implementation that is automatically used if DEBOUNCE is
0 otherwise it will break the _pk/_pr count down.
* Avoid unnecessary polling of the entire matrix in sym_eager_pk
The matrix only needs to be updated when a debounce timer expires.
* Avoid unnecessary polling of the entire matrix in sym_eager_pr
The matrix only needs to be updated when a debounce timer expires.
The use of the "needed_update" variable is trying to do what
"matrix_need_update" was added to fix but didn't work because it only
applied when all keys finished debouncing.
* Fix sym_defer_g timing inconsistency compared to other debounce algorithms
DEBOUNCE=5 should process the key after 5ms, not 6ms
* Add debounce tests
* Use memcmp to determine if matrix changed.
* Firmware size issues.
* Add documentation for the lack of need of MATRIX_ROW_PINS/MATRIX_COL_PINS, when overriding low-level matrix functions.
* Set bootloader to stm32-dfu for STM32F303
* Set bootloader to stm32-dfu for STM32F0x2
* Set bootloader to stm32-dfu for STM32F4x1
* Set bootloader to stm32duino for sowbug
* Delete redundant bootloader_defs headers
* Add some missing MCU name comments
* Move APM32 dfu-suffix overrides underneath bootloader
* Remove redundant STM32_BOOTLOADER_ADDRESS defines/rules
* add readPort() and some API to 'tmk_core/common/*/gpio.h'
The following macros have been added to gpio.h.
* readPort(port)
* setPortBitInput(port, bit)
* setPortBitInputHigh(port, bit)
* setPortBitOutput(port, bit)
* writePortBitLow(port, bit)
* writePortBitHigh(port, bit)
* add data type 'port_data_t' into gpio.h
* rename qmk_pin to pin

Debian bullseye (testing at the moment, but seems close to release) has
avr-libc 1:2.0.0+Atmel3.6.2-1.1 with some changes taken from the
Atmel-distributed toolchain. In particular, the <avr/io.h> header for
ATmega32A (avr/iom32a.h) now defines the FLASHEND constant as `0x7FFFU`,
and that `U` suffix breaks the firmware size check code, because the
shell arithmetic expansion that is used to calculate `MAX_SIZE` does not
support those C-specific suffixes.
As a workaround, add `-D__ASSEMBLER__` to the C preprocessor invocation
that is used to expand those macros; in this case avr/iom32a.h defines
`FLASHEND` without the `U` suffix, and everything works as it did before
with older avr-libc versions.
The exact same code is present in two places; they are both changed,
even though the code in `tmk_core/avr.mk` is actually never used for
ATmega32A (and the header for ATmega32U4 does not add that `U` suffix to
`FLASHEND` for some reason).
