In some cases, the system wasn't able to turn off
because the GUI service got stuck. The device
was still working in the background. The cause
was an empty queue in DrawCommandQueue which
hang the GUI worker.
The interface was modified and synchronization
mechanism was removed.
The thread no longer waits in dequeue().
Also changed the worker to close in the right
way the logger worker.
1. Implement partial refresh.
2. Implement refresh canceling mechanism.
3. Refactor some parts of the gui and display code.
ad 1.
- Detect parts of the screen changed since last update and merge them
into bigger regions. These regions defines parts of the context sent
to the display.
- Refresh the region covering all of the parts since this is the most
time consuming part and the size of the refreshed region doesn't
change the time much.
- Refresh the whole screen if deep refresh is requested and previously
fast refresh was used. This is needed to prevent unwanted artifacts
in some cases.
ad 2.
- Separate display update and refresh logic.
- Divide image display message handling into two handlers, one updating
and other one refreshing the screen.
- Add cancel refresh message and use it to cancel refresh during update.
- Store sum of refresh regions gathered during updates to refresh them
all at once at the end.
* Dependencies between service-gui and service-eink
have been correctly defined.
* System close routine was replaced with the sequential one
which should solve many bell issues.
* It also fixes BH-1406 and BH-1442.
* Fixed some weird CMake issues in module-audio and
several other modules.
* Fixed service-gui closing routine
* Removed unneeded messages/states from service-gui/eink.
* Enhanced app-mgr closing routine. Fixed closing action handling.
Split module-utils into smaller components for better dependency
management. Fix many dependencies throughout the project.

Add new window to allow convenient display and globally
change used color intensities for design and testing purposes.
Changes were introduced to Renderer as well as GUI service
to allow global change of used color scheme.
When using list, screen is deep refreshed each
time the color is changed.
Known issues:
Item focus borders (top,bottom) with changed black intensity
may not render properly, however it doesn't obscure the
target functionality.
* allow workers to run independently from service
* change worker to use FreeRTOS wrapper Queue class instead of
freeRTOS native queues
* fix bug disallowing to destruct worker that have never ran
* fixed worker bad state transition to Running state
* EGD-3585 SerwiceGUI and ServiceEink initial cleanup
* moved code to one function per message handling
* removed dead code from comments
* added Service.cpp demangling to debug messages for clear output
* added Response value to return messages to `connect()`
* Timers now are Application thread safe
* Timers now have consistent API independend of Application (no more c style timers)
* Timers can have either: callback or override onTimer() method - this
way we can create more complicated timers or just use existing ones
* gui::Timer added via adapter class GuiTimer to decouple sys::Timer
with gui::Timer
* Fixed race in wrapper
* Updated docs
* fixed using std and cpp_freertos and DataReceivedHandler hidden in Application.hpp
