[winswitch] [ANNOUNCE] Xpra 2.4.1: minor fixes

[Antoine Martin]

Hi,

This update fixes some regressions in the handling of popup windows (one
recent and one much older), the clipboard code, the session info window
and the NVENC encoder. There are also a fair few build and packaging
related issues. The rest is mostly cosmetic.

There is no urgency to update if you were not affected by those issues.


Release notes:
* fix popup window focus for some Java applications
* fix popup window focus issue (ie: xterm menu)
* fix system tray errors when mmap is disabled
* fix missing system tray under Ubuntu's Unity (DEB dependency issue)
* fix error in debug logging on MS Windows
* fix missing codecs (numpy was blocked from loading)
* fix nvenc compatibility with more python / cython / OS versions
* fix backwards compatibility in keyboard mapping
* fix session info errors when connecting to older servers
* fix default value 'auto' for ssh option, better compatibility
* fix dead code triggering some debug warnings
* fix rare race condition when closing a connection
* fix 'flush' client encoding options parsing
* fix overzealous clipboard sanitization code
* fix missing notification messages
* fix ssh client authentication: try all keys found
* fix version update check
* fix usability issues with GTK3, especially on MS Windows
* fix cython compilation warnings
* fix x264 dependency for Debian Buster
* fix man page typo
* update default DEB build options for newer distributions
* removed outdated DEB dependency on xvidcore
* avoid ethtool warning spam
* use correct headers for building python3 cairo workaround module
