This was previously done in the component itself, but that was removed
in 711789908b0c6c0f76597596d567fba4ae9151ca (plasma-framework). For the
most part, buttons look better without the old minimum width, but these
buttons here relied on that behavior and do in fact look better with it.
So let's set it manually on these buttons.

The new network plugin has simplified names for the network sensors.

Better to keep the exact semantics when porting stuff, we can change it later
if we want. (Disregarding that I even got the boolean the wrong way around).

We have a situation where some clients drop their old offer before
creating a new one. This means klipper tries to fill in the empty
clipboard at the same time the client posts its new real contents.

This adds in a flag (via a hidden mimetype) that klipper is trying to
replace a null clipboard. If this flag is set and our clipboard is not
null because the client has updated it in the meantime we ignore the
klipper update.

It's a workaround, rather than an ideal fix at a data level, but it
solves the problem in the interim.

Systemd doesn't like values containing escape sequence \033 and a fix
won't be accepted upstream. Users of QT_MESSAGE_PATTERN might have this
set already. The big problem is then we can fail to update important
variables such as DISPLAY which all comes as one big update.

This then makes ksyncdbusenv obsolete as that was the only user of this.

This makes client code easier and faster.
A test is included.

CoreAddons is needed publicly as the public UpdateLaunchEnvJob inherits
from KJob. Plasma is not needed at all.

Right now this functionality is only offered through the context menu,
which of course is not available on touch. This commit adds a simple
toolbutton in the applet's toolbar to show the Energy KCM.

FEATURE: 409107
FIXED-IN: 5.20

Use new SettingStateBinding introduced by frameworks/kdeclarative!4 and
also to support highlight of non default settings

see breeze!12

Only appears in Software Centers I presume.

This fixes a PC3 porting regression introduced with
f55b00fe.

Support for this was added in frameworks/plasma-framework@b7ee6962

So there's no need to roll our own solution anymore.

After much much much VDG discussion, it turned out that we don't
actually want to make the System Tray icons scale with the panel. We
returned to that with 31c7ebe3, but one
element remained: to make the icons automatically become a
two/row/column layout for thick panels, as we had for Plasma 5.19 and
earlier. This commit does that, and in the process simplifies the
configuration UI to show only the two options that we decided make sense:

1. Small icons that become two-row/column for thick panels
2. Auto-sizing icons that match the size of other panel widgets

Number one returns to being the default as it was before, and number two
is available for people/themes that want all icons to match in size.

Using 'IMPORTED_TARGET' with pkg_check_modules requires CMake 3.6.

BUG: 423155

Qt 5.15 introduces a new syntax for connections.

Framework code can't port away due to having to support Qt5.12 which
does not include the new syntax.

This filters out the category.

We should remove this once we depend on Qt5.15 in frameworks.

BUG: 424259

Otherwise fails to build here with 'Unknown CMake command "pkg_check_modules"'.

This requires (though not hard) the code found in
frameworks/knewstuff!23 and the
idea behind this is to clean up KNewStuff's knowledge of entries which
have been deleted without telling KNewStuff about it first. This is a
further step towards fixing the bug below.

CCBUG:417985

After many many many VDG discussions, we decided to shelve the idea of
making system tray icons scale with the panel thickness by default. Too
many people didn't consider it a visual improvement. People who do like
this setting can still enable it here if they want, but it's no longer
the default.

Hopefully fixes the BSD CI where it's not available at build time.

Adapt to API changes

To be used for thumbnails in plasma-desktop and plasma-phone-components

internalId wasn't meant to be used and is deprecated.

BUG: 423953

QDBusConnectionInterface::serviceOwnerChanged is obsolete. It was used
because there was no support for watchin on serviwes usign wildcard.
Starting from Qt 5.14 it is possible, so that using obsolete function is
no longer necessary.

On wayland the concept of an empty clipboard is presented differently.
The case where we're not syncing the clipboard was not guarded
correctly.
