* Port to meson
* plugin generation script: swtich to meson, update to python3, switch to libpeas, add some extra options, and cleanup
* clean up some build warnings
* kill xed-bugreport.sh with fire: it isn't used anymore, and probably doesn't even work
* update gzip command to avoid warnings on some systems and move appdata.xml to /usr/share/metainfo/ as that's where it's supposed to go now
* POTFILES.in: fix path that changed in the meson port, which was causing makepot to fail
All the the old python plugins have already been removed. Remove a bunch of the
other related cruft since we want to port the plugin system to libpeas
