libostree:

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 [link moved to references]

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 ... [Please see the references for more information on the vulnerabilities]");
