* ci: Use new codecov uploader
The bash uploader is deprecated
Ref: https://about.codecov.io/blog/codecov-uploader-deprecation-plan/
* Collect coverage report using lcov
* Remove branch coverage
There are a lot of hidden branches in the C++ code which doesn't make it
very useful
* build: Add -Wsuggest-override
We should always use the override specifier when overriding virtual
functions. This helps prevent errors when a subclass tries to create a
function with the same name as a virtual function in a super-class but
with a different purpose.
* clang-format
* Upload logs on failure
* Add override to unsupported.hpp
* cmake: Make -Wsuggest-override flag conditional
Each major target of polybar can now be enabled/disabled while
configuring (even polybar itself).
The cmake code specific to each target will only run if the target is
enabled.
This allows us to for example just build the documentation without
having to run all the cmake code related to compilation or having the
polybar dependencies installed (other than sphinx).
