Add support in the soup and curl fetchers to send the `If-None-Match`
and `If-Modified-Since` request headers, and pass on the `ETag` and
`Last-Modified` response headers.
This currently introduces no functional changes, but once call sites
provide the appropriate integration, this will allow HTTP caching to
happen with requests (typically with metadata requests, where the data
is not immutable due to being content-addressed). That should reduce
bandwidth requirements.

Add G_IO_ERROR_PARTIAL_INPUT to the list of error codes caused by
transient networking errors which lead us to retry the request. When
attempting to install the spotify flatpak you often get the error
message "Connection terminated unexpectedly" and the download of the deb
file fails. In this case, libsoup is setting G_IO_ERROR_PARTIAL_INPUT
and sometimes a subsequent download attempt is successful, so we should
treat it as transient.
Ideally we would behave as wget does in this case and retry the download
picking up where we left off in the file rather than starting over, but
that would require changes to libsoup I think.
Sadly this patch does not fix the flatpak installation of spotify in the
face of such errors, because flatpak doesn't use libostree to download
extra data, but presumably it's possible we could encounter such an
error pulling from an ostree repo, so the patch is still correct.
Use GIOErrorEnum as the return value for
_ostree_fetcher_http_status_code_to_io_error(), to avoid an
implicit cast from GIOError.

Rather than wrapping each instance of `sd_journal_*` with
`HAVE_SYSTEMD`, let's just add some convenience macros that are just
no-op if we're not compiling with systemd.

Use the same G_IO_ERROR_* values for HTTP status codes in both fetchers.
The libsoup fetcher still handles a few more internal error codes than
the libcurl one; this could be built on in future.

Allow network requests to be re-queued if they failed with a transient
error, such as a socket timeout. Retry each request up to a limit
(default: 5), and only then fail the entire pull and propagate the error
to the caller.
Add a new ostree_repo_pull_with_options() option, n-network-retries, to
control the number of retries (including setting it back to the old
default of 0, if the caller wants).
Currently, retries are not supported for FetchDeltaSuperData requests,
as they are not queued. Once they are queued, adding support for retries
should be trivial. A FIXME comment has been left for this.

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

We added a `.dir-locals.el` in commit: 9a77017d87
There's no need to have it per-file, with that people might think
to add other editors, which is the wrong direction.

Currently in Fedora we don't sign summaries, and every use of
`rpm-ostree` would emit to the journal an error when we failed
to fetch it.
Fix this by having `OSTREE_FETCHER_REQUEST_OPTIONAL_CONTENT` tell the fetcher
not to journal 404 errors. While fixing this, we had a mix of two booleans vs
the flags; fix things so we consistently use the flags in the fetcher and pull
code.
Closes: #1004

Particularly when HTTP requests fail, I really want a lot more information.
We could theoretically stuff it into the `GError` message field, but
that gets ugly *fast*.
Using the systemd journal allows us to log things in a structured fashion.
Right now e.g. rpm-ostree won't be aware of this additional information,
but I think we could teach it to be down the line.
In the short term, users can learn to find it from `systemctl status rpm-ostreed`
or `journalctl -b -r -u rpm-ostreed`, etc.
One thing I'd like to do next is log successful fetches of e.g. commit objects
as well with more information about the originating server (things like the
final URL if we were redirected, did we use TLS pinning, what was the negotiated
TLS version+cipher, etc).

The previous commit introduced a single low level API - however,
we can do things in a more optimal way for the curl backend if
we drop the "streaming API" variant. Currently, we only use
it to synchronously splice into a memory buffer...which is pretty
silly when we could just do that in the backend.
The only tweak here is that we have an "add NUL character" flag that is
(possibly) needed when fetching into a membuf.
The code here ends up being better I think, since we avoid the double return
value for the `_finish()` invocation, and now most of the fetcher code (in the
soup case) writes to a `GOutputStream` consistently.
This will again make things easier for a curl backend.
Closes: #636

Conceptually these now lay on top of the core API, and don't reference libsoup.
This is preparation for libcurl porting, but it's also just generally better.
