This is now in xdg-desktop-portal. We keep a version of the document
portal dbus XML so that we avoid weird build dependencies.
Flatpak itself is technically not dependent on the document portal,
but it is very much recommended that you use it.
Closes: #1398
Approved by: alexlarsson
Many flatpak commands only work on *.flatpak or *.flatpakref files, so
the bash auto completion showing every file is distracting and
unnecessary. This commit makes flatpak only show relevant files when
possible by using the "-G globpattern" compgen option.
This adds --forbid-read, --forbid-write, --forbid-delete and
--forbid-grant-permissons options to flatpaks document-export
command, to let it revoke permissions on exported documents.
