* Fix flash writes that don't end on a sector boundary. Fixes#2944
* Fix enum incompatibility with IDF.
* Fix printf output so it goes out debug UART.
* Increase stack size to 8k.
* Fix sleep of less than a tick so it doesn't crash.
Length was stored as a 16-bit number always. Most translations have
a max length far less. For example, US English translation lengths
always fit in just 8 bits. probably all languages fit in 9 bits.
This also has the side effect of reducing the alignment of
compressed_string_t from 2 bytes to 1.
testing performed: ran in german and english on pyruler, printed messages
looked right.
Firmware size, en_US
Before: 3044 bytes free in flash
After: 3408 bytes free in flash
Firmware size, de_DE (with #2967 merged to restore translations)
Before: 1236 bytes free in flash
After: 1600 bytes free in flash
This pulls all common functionality into `shared-bindings` and keeps
platform-specific code inside `nrf`. Additionally, this performs most
validation in the `shared-bindings` site.
The only validation that occurs inside platform-specific `common-hal`
code is related to timeout limits that are platform-specific.
Additionally, all documentation is now inside the `shared-bindings`
directory.

With this patch, the exception can now be caught:
import microcontroller
import watchdog
import time
wdt = microcontroller.watchdog
wdt.timeout = 5
while True:
wdt.mode = watchdog.WatchDogMode.RAISE
print("Starting loop -- should exit after five seconds")
try:
while True:
time.sleep(10)
# pass # This also works for a spinloop
except watchdog.WatchDogTimeout as e:
print("Watchdog Expired (PASS)")
except Exception as e:
print("Other exception (FAIL)")
print("Exited loop")
This prints:
Starting loop -- should exit after five seconds
Watchdog Expired (PASS)
Starting loop -- should exit after five seconds
Watchdog Expired (PASS)
Starting loop -- should exit after five seconds
Watchdog Expired (PASS)

The previous setting of `1` meant that the bluetooth system couldn't be
used when the watchdog timer was enabled.

As part of the reset process, save the current tick count to an
uninitialized memory location. That way, the current tick value will be
preserved across reboots.
A reboot will cause us to lose a certain number of ticks, depending on
how long a reboot takes, however if reboots are infrequent then this
will not be a large amount of time lost.

For `microcontroller.reset()`, don't manually call NVIC_SystemReset().
Instead, call the `port_reset()` in case the port wants to do any
cleanup.

This finishes the rework of the exception handler, which is once
again stored inside the watchdog timer module.
This also implements a `watchdog_reset()` that is used to disable the
RAISE watchdog, if one is enabled.

Check to see if the current exception is a Watchdog exception, if it's
enabled. This ensures we break out of the current sleep() if a watchdog
timeout hits.

This adds an exception to be raised when the WatchDogTimer times out.
Note that this currently causes a HardFault, and it's not clear why it's
not behaving properly.
