* Drops support for mocking the frontlight setting internally which may
cause incorrect in-memory values.
* Adds new supported value for `KOBO_LIGHT_ON_START` (-2), which sets
'Kobo eReader.conf' as the source to update `settings.reader.lua`'s
brightness setting on startup, thus using the value from it
indirectly.
* Adds the `KOBO_SYNC_BRIGHTNESS_WITH_NICKEL` configuration variable
which updates 'Kobo eReader.conf' every time the brightness setting is
changed within koreader.
* Fixes missing call to save brightness when modifying via two-finger
swipe.
Closes#1523.
_checkTasks first get number of tasks in the stack and does a numeric
for loop to go through each task. The problem is a task might call
schedule or unschedule, which will reorder tasks in the stack. This will
invalidate many of the table indexes used in the for loop.
This patch turns the task stack into an ordered queue, so _checkTasks
only pops one item out of the queue each time instead of setting up a
for loop at the beginning. This should avoid the race condition
mentioned above.
Making sure to always show up to date info.
Also fix the battery polling cache invalidation logic to actually
work?
Should make it behave properly on devices where we handle resuming
ourselves.
Currently only tested on Ubuntu-touch emulator with framework
ubuntu-sdk-14.10 for armhf.
The ubuntu-touch port is binary compatible with the Kobo port
major changes in this PR are:
1. rename the emulator device to sdl device since both the emulator
and the ubuntu-touch target use libsdl to handle input/output.
2. ubuntu-touch app has no write access to the installation dir so
all write-outs should be in a seperate dir definded in `datastorage`.
And also probably prevent a crash when trying to enable WiFi there.
We really shouldn't even show the WiFi stuff on some of these old
devices, but at least now it doesn't crash ;).
