Sam Spilsbury 002e5eeac6 avahi: Don't complain with g_warning if the daemon wasn't running
This is a normal case when running unit tests in client code
on continuous integration infrastructure. When those tests are
running they will set G_DEBUG=fatal-warnings which will cause
the program to abort if a warning is emitted. Instead, emit
a debug message if the problem was that we couldn't connect to
the daemon.

Matthew Leeds cb3360fca6 lib/repo: Add timestamps to OstreeRepoFinderResult
Currently OstreeRepoFinderResult, a data structure used by pull code
that supports P2P operations, has a hash table mapping refs to checksums
but doesn't include timestamp information. This means that clients have
no way of knowing just from the OstreeRepoFinderResult information if a
commit being offered by a peer remote is an update or downgrade until
they start pulling it. The client could check the summary or the commit
metadata for the timestamps, but this requires adding the temporary
remotes to the repo config, and ostree is already checking timestamps
before returning the results, so I think it makes more sense for them to
be returned rather than leaving it to the client. This limitation is
especially important for offline computers, because for online computers
the latest commit available from any remote is the latest commit,
period.

This commit adds a "ref_to_timestamp" hash table to
OstreeRepoFinderResult that is symmetric to "ref_to_checksum" in that it
shares the same keys. This is an API break, but it's part of the
experimental API, and none of the current users of that (flatpak,
eos-updater, and gnome-software) are affected. See the documentation for
more details on "ref_to_timestamp". One thing to note is the data
structure currently gets initialized in find_remotes_cb(), so only users
of ostree_repo_find_remotes_async() will get them, not users of, say,
ostree_repo_finder_resolve_all_async(). This is because the individual
OstreeRepoFinder implementations don't currently access the timestamps
(but I think this could be changed in the future if there's a need).

This commit will allow P2P support to be added to
flatpak_installation_list_installed_refs_for_update, which will allow
GNOME Software to update apps from USB drives while offline (it's
already possible online).

Marcus Folkesson 6bf4b3e1d8 Add SPDX-License-Identifier to source files
SPDX License List is a list of (common) open source
licenses that can be referred to by a “short identifier”.
It has several advantages compared to the common "license header texts"
usually found in source files.

Some of the advantages:
* It is precise; there is no ambiguity due to variations in license header
  text
* It is language neutral
* It is easy to machine process
* It is concise
* It is simple and can be used without much cost in interpreted
  environments like java Script, etc.
* An SPDX license identifier is immutable.
* It provides simple guidance for developers who want to make sure the
  license for their code is respected

See http://spdx.org for further reading.

Philip Withnall 90680e1b29 lib/repo-finder-avahi: Fix memory corruption of a GVariantIter
A GVariantIter* was being passed to a GVariant format string varargs,
rather than a GVariantIter**. This resulted in memory corruption.

So we can continue to reuse ref_map throughout the function, make it a
GVariantIter* rather than a stack-allocated GVariantIter.

Philip Withnall a1f020ffa4 lib/repo-finder-avahi: Fix a leak in a GVariantIter loop
Use g_variant_iter_loop() rather than next(), since it automatically
handles freeing the child memory each iteration. Previously, we leaked
it for all but the last iteration.

Philip Withnall 69e332a0c0 lib/remote: Store name of remote providing keyring for dynamic remotes
When pulling from a dynamic (peer to peer) remote, the remote’s name is
set to a unique, generated string which doesn’t exist in repo/config. If
doing a non-mirror pull, however, we don’t want to use this name in the
refspecs for newly created or updated refs — we want to use the name of
the remote which provided the keyring for the pull (this will be a
remote from repo/config whose collection ID matches that being used for
the peer to peer pull).

Store both names in OstreeRemote. The name to use for refspecs is stored
as refspec_name, and is typically NULL unless it differs from name.

Philip Withnall 22c1fdfbd3 lib/repo: Change resolve_keyring_for_collection() to return a remote
Instead of returning just the keyring filename, return the entire
OstreeRemote, which has the keyring filename as one of its members. This
will simplify some upcoming changes, and allows slightly improved debug
logging.

Philip Withnall 8c148eb7e1 lib/repo-finder: Emit gpg-verify-summary=false in dynamic remote config
When returning results from finding repos, set gpg-verify-summary=false
in their configs, since any pulls from such remotes will necessarily
involve collection IDs, and hence should be using the unsigned summary
support. In the intended deployment mode for P2P transmission of OSTree
refs, summaries *cannot* be signed, so setting gpg-verify-summary=true
would cause all the pulls to fail.

The unsigned summary support is the move of repository metadata from
the summary file (not spliceable) to the well-known ostree-metadata ref
(spliceable, as it can exist for multiple collection IDs in the same
repository).

Philip Withnall 1672e2eee0 lib/repo: Fix handling of missing summary files when downloading
The API for downloading a summary file can legitimately return NULL for
the summary file contents when it returns TRUE (success). This indicates
an error 404 — the summary file was not found.

Two call sites were not handling that correctly, which was causing later
assertion failures.

Philip Withnall e3d4eeacbc lib/repo-finder: Add Avahi based OstreeRepoFinder implementation
This is a more complex implementation of OstreeRepoFinder which resolves
ref names to remote URIs by looking for refs advertised by peers on the
local network using DNS-SD records and mDNS (Avahi). The idea is to
allow OS and app updates to be propagated over local networks, without
the internet.

It requires an OSTree server and code to generate the DNS-SD adverts in
order to be fully functional — support for this will be added
separately.

Unit tests are included.

Includes fixes by Krzesimir Nowak <krzesimir@kinvolk.io>.
