PlasmoidHeader was probably based on T.Frame because of a mistake. T.Frame doesn't do anything different from T.Pane and PlasmoidHeader was duplicating the function of T.ToolBar's position property with the location property.
Instead of checking for existance and then getting the value. Look it up
once and use the value if avaliable.
This saves us one hash look-up per execution which can be considerable,
especially in the case of findElementRect.
CMake's FindOpenGL internally handles EGL only correctly when GLVND is
available. This might not the case on embedded systems and actually it
is not necessary when EGL::EGL is found.

The intent behind this code seemingly was that KGlobalAccel would
update the shortcut of the QAction but that is not the case. This
leads to our config going out of sync when global shortcuts are
changed from the oustide (the kcm) and resetting on next start
since we set shortcuts with NoAutoLoading.

I was looking into why there is so much time spent here for the logout
greeter that only has buttons. It seems like we were querying the cache
file every time even though we already have separate code that checks
whether our information is valid.
As I started looking into it, ::loadImageFromCache was %25 of the CPU
time. After this patch it's short of 1%.

The explicit version checks are not needed anymore, the plugins are
installed into a specific namespace for each major version. Also the
plasma-frameworks API is stable during the lifetime of a major version.
In **general**, variables in `if()` commands should not be expanded
"by hand" before use, because substitution occurs before the `if()`
command is parsed: in practice that means that a command like
if(${A} STREQUAL "A")
can expand to (depending on the value of A being empty, "B" or "A")
if( STREQUAL "A")
if(B STREQUAL "A")
if(A STREQUAL "A")
Then the `if()` command is processed, leading to:
- a syntax error
- comparing the value of variable B against string "A"
- comparing the value of variable A (it's "A" because that
is what `${A}` expanded to) against string "A"
This is explained in section *Variable Expansion* of the documentation
of the `if()` command, but keeps tripping people up.
The K_EXPORT_PLASMA_DATAENGINE_WITH_JSON expects a JSON file. But
considering that nobody complained about this and it has been broken for
years we can get rid of it.
The mechanism was used to make those files accessible to
KServiceTypeTrader, but that is not used anymore by KPackage.
KPackage can already handle JSON files for all its functionality,
consequently there is no reason to enforce having desktop files.
It messes with QtQuick Layouts in various ways and experience from
PlasmaComponents 2 has shown that giving `Label` any kind of explicit
size is just asking for trouble.
This reverts commit a4e4156a47.
And simplify code:
* Add constant for the max number of events that can be displayed at the
same time
* Use std::min to simplify a bit the code
* Rename nextIndex to addedEventCount
