Security update for flatpak, libostree, xdg-desktop-portal, xdg-desktop-portal-gtk

This update for flatpak, libostree, xdg-desktop-portal, xdg-desktop-portal-gtk fixes the following issues:


Update to version 2020.8

- Enable LTO. (bsc#1133120)

- This update contains scalability improvements and bugfixes.
- Caching-related HTTP headers are now supported on summaries and signatures, so that they do not have to be
re-downloaded if not changed in the meanwhile.
- Summaries and delta have been reworked to allow more fine-grained fetching.
- Fixes several bugs related to atomic variables, HTTP timeouts, and 32-bit architectures.
- Static deltas can now be signed to more easily support offline verification.
- There's now support for multiple initramfs images; Is it possible to have a "main" initramfs image and a
secondary one which represents local configuration.
- The documentation is now moved to
- Fix for an assertion failure when upgrading from systems before ostree supported devicetree.
- ostree no longer hardlinks zero sized files to avoid hitting filesystem maximum link counts.
- ostree now supports `/` and `/boot` being on the same filesystem.
- Improvements to the GObject Introspection metadata, some (cosmetic) static analyzer fixes, a fix for
the immutable bit on s390x, dropping a deprecated bit in the systemd unit file.
- Fix a regression 2020.4 where the "readonly sysroot" changes incorrectly left the sysroot read-only
on systems that started out with a read-only `/` (most of them, e.g. Fedora Silverblue/IoT at least).
- The default dracut config now enables reproducibility.
- There is a new ostree admin unlock `--transient`. This should to be a foundation for further support
for "live" updates.
- New `ed25519` signing support, powered by `libsodium`.
- stree commit gained a new `--base` argument, which significantly simplifies constructing "derived"
commits, particularly for systems using SELinux.
- Handling of the read-only sysroot was reimplemented to run in the initramfs and be more reliable.
Enabling the `readonly=true` flag in the repo config is recommended.
- Several fixes in locking for the temporary "staging" directories OSTree creates, particularly on NFS.
- A new `timestamp-check-from-rev` option was added for pulls, which makes downgrade protection more
reliable and will be used by Fedora CoreOS.
- Several fixes and enhancements made for "collection" pulls including a new `--mirror` option.
- The ostree commit command learned a new `--mode-ro-executables` which enforces `W^R` semantics
on all executables.
- Added a new commit metadata key `OSTREE_COMMIT_META_KEY_ARCHITECTURE` to help standardize
the architecture of the OSTree commit. This could be used on the client side for example to
sanity-check that the commit matches the architecture of the machine before deploying.
- Stop invalid usage of `%_libexecdir`:
+ Use `%{_prefix}/lib` where appropriate.
+ Use `_systemdgeneratordir` for the systemd-generators.
+ Define `_dracutmodulesdir` based on `dracut.pc`. Add BuildRequires(dracut) for this to work.


Update to version 1.8.0:

- Ensure systemd rpm macros are called at install/uninstall times for systemd user services.

Without it, files or dirs can be selected, but whatever is done with or in them, will not have any effect
- Fixes for `%_libexecdir` changing to `/usr/libexec`

- Update to version 1.10.2 (jsc#SLE-17238, ECO-3148)

`.desktop` file to gain access to files on the host system.
- Fix memory leaks
- Documentation and translations updates
- Spawn portal better handles non-utf8 filenames
- Fix flatpak build on systems with setuid bwrap
- Fix crash on updating apps with no deploy data
- Remove deprecated texinfo packaging macros.
- Support for the new repo format which should make updates faster and download less data.
- The systemd generator snippets now call flatpak `--print-updated-env` in place of a bunch of shell for better
login performance.
- The `.profile` snippets now disable GVfs when calling flatpak to avoid spawning a gvfs daemon when logging in via ssh.
- Flatpak now finds the pulseaudio sockets better in uncommon configurations.
- Sandboxes with network access it now also has access to the `systemd-resolved` socket to do dns lookups.

and `--env=FOO=` now sets FOO to the empty string instead of unsetting it.
- The spawn portal now has an option to share the pid namespace with the sub-sandbox.
- This security update fixes a sandbox escape where a malicious application can execute code outside the sandbox by
controlling the environment of the "flatpak run" command when spawning a sub-sandbox (bsc#1180996, CVE-2021-21261)
- Fix support for ppc64.
- Move flatpak-bisect and flatpak-coredumpctl to devel subpackage, allow to remove python3 dependency on main package.

- Fix flatpak run handling of userns in the `--device=all` case
- Fix handling of extensions from different remotes
- Fix flatpak run `--no-session-bus`
- `FlatpakTransaction` has a new signal `install-authenticator` which clients can handle to install authenticators

- Now the host timezone data is always exposed, fixing several apps that had timezone issues.
- There's a new systemd unit (not installed by default) to automatically detect plugged in usb sticks with
