* Removed some legacy files that were
compiled, but not used anywhere.
* Cleaned-up ImageManager and
FontManager implementations, trying
to use RAII wherever possible.
* Fixed minor bugs in Font.cpp
implementation.
* Removed unused includes.
* Other minor cleanups and refactors.
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.

Split module-utils into smaller components for better dependency
management. Fix many dependencies throughout the project.

Add proper catch2 support:
- add catch2 as a submodule
- add cmake function to add test easily
- discover each test in test binary
- remove copies of catch.hpp
- do not try to process tests for rt1051
Do not test internals of utf8, only public interface (nasty bugs could
occur otherwise).
