This is one more step towards making rpm-ostree more powerful in its
quest to be the ultimate *hybrid* image/package system. Package layering
allows us to add packages on top of the base package set received from
the content provider. However, we're not able to remove or replace
packages in the base set itself.
This patch introduces a new `override` command, which is for now nested
under the experimental `ex` command. The `override` command will allow
users to modify the base package set itself. The first implemented
subcommands are `remove` and `reset`.
A stub has been provided for the more useful `replace` subcommand,
though much of the needed logic for that operation are implemented in
this patch as part of the `remove` subcommand.

There's a lot that could be done to improve this; we're not setting a title for
`rollback` etc. But I think in practice right now the "deploy" path (which
includes upgrade/install) etc. is most important.
Re-synthesizing a human readable string here is definitely a bit fragile and
going to be a maintenance pain. One thing I debated is having the client send
its commandline as a string. But that would only work for `/usr/bin/rpm-ostree`,
not e.g. Cockpit.
Anyways for now, this is useful and we can always improve it later.

There are a few different use cases here. First, for layering new packages,
there's no good reason for us to force a reboot. Second, we want some support
for cherry-picking security updates and allowing admins to restart services. Finally,
at some point we should offer support for entirely replacing the running tree
if that's what the user wants.
Until now we've been very conservative, but there's a spectrum here. In
particular, this patch changes things so we push a rollback before we start
doing anything live. I think in practice, many use cases would be totally fine
with doing most changes live, and falling back to the rollback if something went
wrong.
This initial code drop *only* supports live layering of new packages. However,
a lot of the base infrastructure is laid for future work.
For now, this will be classified as an experimental feature, hence `ex livefs`.

`Commit` is useful in cases where one wants to e.g. run `rpm-ostree db diff`.
`StateRoot` however is going to be in the vast majority of cases identical
across deployments.

See: https://github.com/ostreedev/ostree/pull/794
I originally tried to do this ~a year ago in:
https://github.com/projectatomic/rpm-ostree/pull/295
But Micah pushed back at the time. I'd still like to do this
though, since I personally find `OSName` *more* confusing
than `StateRoot`.
One specific rationale I have for making this change is that
I rebased a home server from CentOSAH to FAH - and I feel
it's just saner to see `StateRoot: centos-atomic-host` instead
of `OSName: centos-atomic-host` underneath the fedora refspec.

Add support for --install/--uninstall to upgrade/deploy/rebase by
calling out to UpdateDeployment(). Since it's not released yet, back out
the support for install-local-packages in the options variant for
PkgChange(), and make it instead use UpdateDeployment() as needed.

One interesting note here was that I couldn't use glnx_throw in as many
places as I wanted because EXIT_SUCCESS/EXIT_FAILURE are the exact
opposite of that semantic. It was still convenient to use though as a
short-form for g_set_error().

Following up on the previous commit regarding timestamps - the checksum of the
derived commit isn't very useful. It's not going to be the same between any two
people's systems. What we should show instead is the rpm-md repository
timestamps.
In the short term though, I think omitting this even without the rpm-md
timestamps is better. Less visual clutter.

Currently we propagate the version field from the base to derived,
but the status UI shows the timestamp from the derived commit.
I found this *extremely* confusing when I was trying to reason about the
up-to-dateness of my system. The version and timestamp should be locked
together so we display them consistently.
When we generated the local commit isn't really useful information; conceptually
we have the base timestamp, plus timestamps for the rpm-md repos. We should
display the latter instead.
(This also adds `base-timestamp` and `base-verison` to the JSON; only
the former is new information, but the latter helps us be consistent)

Allow users to directly specify an RPM file on the command-line. The
"packages_added" array of the PkgChange() method can now contain
absolute paths to RPM files.
Grow the origin format to have a new "requested-local" key. This is
similar to the "requested" key, except that the packages are always
installed from cache. The "requested-local" array values also embed the
SHA-256 of the header we expect.
There is now a new "LocalPackages" line in the status. These packages
are a subset of the "packages" element (which are printed as
"LayeredPackages") and represent the packages that are explicitly marked
for installing from cache.
Interesting design choices/notes:
- Just as before, even with foo-1.0-1.x86_64 installed from RPM, a
user can still request "/usr/bin/foo": it will be made dormant. As
soon as foo stops being explicitly layered from the RPM, it will try
to fulfill the request by going to the repos. This allows users to
"pin" a layered package to a certain RPM, and then unpin it.
- The strings/NEVRAs in "requested" and "requested-local" are strictly
distinct. This allows us to be able to tell what the user means
exactly when they do "rpm-ostree uninstall".

This is the culmination of the work paved by the previous commits. We no
longer handle package set mutations in the upgrader, but rather let
clients modify the origin as needed for that. As such, the upgrader is
now completely memoryless. We no longer try to error out if a package is
already in the base and we no longer drop out packages previously
layered packages that are now in the base. *Which* packages actually get
layered is determined during deployment and not coded in the origin.
At an API level, the deployment variant returned (and thus what gets
printed by `status --json`) now has both "packages" and
"requested-packages". The former retains its original semantic: it's the
set of packages that are *actually* layered. The latter contains
everything from the origin, which includes the former set + dormant
packages.
Accordingly, the output of `rpm-ostree status` also now distinguishes
between "RequestedPackages" and "LayeredPackages". Extra: we now quote
provides that contain spaces.

One thing that's very confusing about OSTree is there are two layers -
deployments and the refs/commits. If one does an `rpm-ostree upgrade`, but then
e.g. `ostree admin undeploy 0`, you still have the new revision in the repo.
We don't do a good job of displaying this state, or helping people clean
it up.
Down the line, I also want to better support something like `rpm-ostree pull` to
cache updates explicitly *without* deploying.
This commit just adds a bit of information to the status display. We might want
to have better formatting, but I think this an OK start.

Currently we push for a model where the initramfs is
generated (in non-hostonly mode), and merely replicated.
However, to support a few unfortunate corner cases like dm-multipath which wants
to inject a config file into the initramfs, we need to support regenerating it
client side too.
Down the line, we'll need this to support overriding the kernel too.
This changes things in the core to add the concept of an "empty"
`RpmOstreeContext`. I initially tried skipping it, but that was too much
duplication. We still want all of the core ostree-related logic that lives in
that code too.
The treespec bits barfed if the spec didn't have a `tree/packages` key. It was
simplest to change that to allow it - and because that was the only case where
we errored out in parsing, I dropped the error handling.
There was another place in the upgrader that now needed to be fixed to handle
transitioning from just regenerating initramfs to not.

I kept thinking `^a&s` was sufficient for allocation-free reading
of `as`, but it's not, we need to free the outer buffer. Other
minor cases were using `s` instead of `&s`.

The API for json_generator_to_stream() says:
Return value: %TRUE if the write operation was successful, and
%FALSE on failure. In case of error, the #GError will be filled
accordingly
When in fact, because it just gives back what g_output_stream_write(),
1. it doesn't strictly return TRUE/FALSE, but a full-range uint, and
2. it will return -1 (which is as good as anything > 0 for success
checks) when an error occurs.
Although a simple <= 0 would fix it, let's just be extra strict and also
check for an error.

It's really in-your-face for admins to see `(unsigned)` which originally
was intentional, but in practice right now at least several major
users (Fedora, RHEL) don't enable GPG signatures.
So let's just hide it if not enabled.
Perhaps in the future we should add a `-v` option or something which
would show all of the fields even if not enabled.

Now that the `status` command learned a `--json` option, we can pretty
much avoid parsing human-readable output. The only piece of information
that is missing from the JSON output compared to the output for humans
is *which* deployment we're currently booted in.
This patch fixes that shortcoming by adding a "booted" boolean variant
to the deployment variant.

I really want a command to cancel the running transaction, but as a

With the end goal in mind that I want to optimize for the case
of 1-2 deployments, it's actually a lot simpler to just
nuke the whole current column base.
It just really doesn't make sense with layered packages, and even
before then, I usually found the timestamp and osname columns
redundant.

This patch fixes up errors in the parent commit which added pkg-add.
Some of them are due to the rebase on top of the unprivileged
infrastructure.
- fix compile errors (due to libhif changes after rebase)
- delete duplicate prototype for rpmostree_sysroot_upgrader_deploy
- include allow-older in flags type
- fix change_upgrader_refspec to use g_strdup() (this was causing the
wrong old refspec to be registered)
- in builtin-status.c, check for NULL before joining the packages array
- sysroot-upgrader: fix gtype function names
- roc_context_prepare_for_root(): delete unused param
- assemble_commit(): delete unused param
- RpmOstreeSysrootUpgraderFlags: fix docs
- Fix sysroot property name and add reboot opt

This builds upon the earlier prototype in
https://github.com/cgwalters/atomic-pkglayer
The `.origin` file says for a replicated installation:
[origin]
refspec=local:rhel-atomic-host/7/x86_64/standard
If you then run `rpm-ostree pkg-add strace`, it will result in a new tree with:
[origin]
baserefspec=local:rhel-atomic-host/7/x86_64/standard
[packages]
requested=strace;
Work still remaining here is to teach `rpm-ostree status` and
`rpm-ostree upgrade` about this.

For the columns that can vary in width, check that the minimum width of
the column is at least the length of the column header. Otherwise, we
can run in a situation where some columns are stuck to each other. The
trivial strlen() should be optimized to a constant by the compiler.
Encountered a couple crash scenarios:
1) A commit with an invalid timestamp trips an assertion. Instead
show the timestamp as "invalid".
2) If a deployed commit is unsigned, the daemon will not include a
"signatures" array in the deployment's GVariant representation.
The logic for --pretty was assuming the "signatures" array is
always present.
Change the command callback return type to integer, so commands can
return a custom exit status. Usually it should be EXIT_SUCCESS (0)
or EXIT_FAILURE (1).
In the style of ostree's CLI, add some option parsing flags
RPM_OSTREE_BUILTIN_FLAG_NONE
RPM_OSTREE_BUILTIN_FLAG_LOCAL_CMD
and extend rpmostree_option_context_parse() to handle the --sysroot and
--peer options and return an OstreeSysroot proxy object (unless the flag
RPM_OSTREE_BUILTIN_FLAG_LOCAL_CMD is passed).
If g_dbus_connection_get_unique_name() returns a name, we're connected
to a message bus. Otherwise we're connected directly to a peer.
Remove redundant "out" parameters from DBus helper functions.
In pretty mode (--pretty), print signatures for each listed deployment.
Otherwise, just print signatures for the booted deployment at the end to
preserve the tabular formatting of the deployment list.
We currently have an internal-only library, but the sources for it are
in the same dir as the app. For future work on a public shared
library, we'll need a clearer source structure.
Start by just renaming the app files into `src/app/`, and the internal
private library into `src/libpriv/`, with the appropriate
`Makefile.am` changes.
