this proofs insanely troublesome. because of the way the filetransfer
portal works we need to open() paths before sending them to the portal,
this however means open() on our fuse-redirected paths which behind the
scenes is actually a remote stat() to determine the file type. this is
insanely expensive and just will not ever work for more than a couple of
files.

for the time being we'll disable fuse redirection unless explicitly
opted into via KCOREADDONS_FUSE_REDIRECT so it can still be tested.

CCBUG: 457529

We want to get rid of this executable, because we also get rid of the underlying service types.
Most places except some small Plasma stuff and Konqueror have already been ported away from it.

Also, the executable file would not be co-installable, because it is not versioned.

We require CMake 3.16 since quite a while

The CI image issue is solved now

This removes code duplication.

Host tooling is still installed as KF5 for compatibility with KF5 Qt6 builds

KEmoticons is gone in KF6. Instead add a basic smiley to Unicode emoji
replacement based on the old KEmoticons code, so the corresponding feature
in KTextToHtml still works.

For the moment we have to support using the tooling for both KF5 and KF6, so temporarily revert to the old naming until the infrastructure side of this is figured out

Also temporarily relax the version check for the tooling to allow building KF5 and KF6 against the same host tools

master is for Qt6-based development now

Qt5 development continues in the 'kf5' branch

Otherwise the process errors out in unexpected ways, this way we know
what's going on and offer an alternative that is sound to some extent.
