Because the reporting of battery state is inconsistent between different
models, the device's battery state was not correctly processed in GB.
For at least the firmware on the Xiaomi Watch S1 Active, the charger
state is broadcast through a separate message from the message
containing the battery level. Even though the battery level was
requested by GB upon receiving this broadcast, the charger state got
discarded as it was expected to also be included in the result of the
subsequent request.
This patch changes the name of the `Charger` message to `DeviceState`
and includes more fields that may be presented by some device models.
Furthemore, the broadcast is cached so that the charger state can be
processed from this cache instead of the battery level response message.
Exceptions raised while handling actions in the device's support class
may result in the DeviceCommunicationService crashing as a whole and not
being started again until the user forces GB to make a connection by
pressing the device from the list.
This change is made, because Xiaomi devices make use of proto2 messages,
where optional fields cannot be set to null values as that will make it
throw NPEs.
This will prevent uncaught exceptions that occur during the
parsing of activity data from breaking up the activity fetching
chain and causing the task to never get completed.
The activity parser may return null pointers in case the version
of the data structure is not supported. Not checking for null here may
result in the activity fetching task may never complete and cause
further communication with the device to grind to a halt.
The Xiaomi Watch S1 Active does not send some fields that have
been declared as `required`, which results in those messages
not being processed at all.
We should use NFKD instead of NFD since we are flattening to US-ASCII
afterwards anyway. This allows various Unicode characters which would
end up as a question mark to be represented by their compatibility
decomposition. This applies to e.g. ligatures (e.g. U+FB01 LATIN SMALL
LIGATURE FI will now be replaced with plain fi instead of a question
mark), and also the U+00A0 NO-BREAK SPACE [NBSP] to be replaced by
a normal space instead of a question mark.
